Jinghong - Chiang Saen (Thailand, 344 km, cruises 10 hours). The upper Mekong flows through Southern China, Burma and Laos and is now opened to foreigners. We join an express boat for the spectacular daytime journey to the Golden Triangle. We hope to land at a Laotian Aini Village. After our exhilarating boat ride we reach the Golden Triangle region between Burma, Laos and Thailand and disembark at Chiang Saen at 18:00.
--Mekong River:
The Mekong is a river in Southeast Asia. It is the world's 10th-longest river and the 7th-longest in Asia. Its estimated length is 4,909 km (3,050 mi),[1] and it drains an area of 795,000 km2 (307,000 sq mi), discharging 475 km3 of water annually. From the Tibetan Plateau this river runs through China's Yunnan province, Burma, Laos, Thailand, Cambodia and Vietnam. Laos, Thailand, Cambodia and Vietnam established the Mekong River Commission in 1995 to assist in the management and coordinated use of the Mekong's resources. 
In 1996 China and Burma became "dialogue partners" of the MRC and the six countries now work together within a cooperative framework. The extreme seasonal variations in flow and the presence of rapids and waterfalls in this river have made navigation extremely difficult.
--Golden Triangle or Chiang Saen: 
Chiang Saen, just south of the Golden Triangle tourist hell hole, is a quiet and very historic town that sits by the Mekong River and was once an independent kingdom. Archaeological finds in the area have placed development here in prehistoric times. More recent communities have been placed in the region of the 13th to 14th Centuries when one of the sons of King Mangrai, Saen Pu, on his father's orders commenced construction of a walled city with the Mekong River being one of those borders.

 
In the morning you will visit the Doi Tung Botanical Gardens in a beautiful hilltop setting within this notorious region, where the King and Queen of Thailand have encouraged modern crops to replace opium poppies. We visit the Hall of Opium to learn about this crop in a spectacular underground setting. We also visit the Giant Buddha, overlooking the Mekong at Sop Ruak, and the smugglers’ town of Mai Sai on the Thai/Burmese border, where thousands of stalls sell contraband.
After lunch, take the speed boat to Houay Xay Boat (1hour).One stop is made to visit and admire the authentic rural life of hill tribe settlements. Arrive in Houay Xay, cross the Thailand-Laos border, then continue the cruise to Pakbeng (3.5 hours). You will pass areas of un-spoilt forest with little villages along the riverbanks and perhaps the odd elephant or two with his mahout. You are going to visit a fishing village as well. You will arrive in Pakbeng around sunset.
--The Hall of Opium at the Golden Triangle Park houses several sections to be explored and various exhibitions to be contemplated. For example, the 5,600 square-meter Hall of Opium presents An Invitation to the Mysterious World of Opium from Darkness to Light, the history of opium as of 5,000 years ago from its natural properties to its uses. It traces opium's global journey through trade routes in the age of imperialism, culminating in the Opium Wars-an event that disgraced both winners and losers that led to the fall of the Manchu Dynasty. It also features Siamese wisdom in confronting the West and the eventual control of opium problems.
--Ban Houayxay also known as Huay Xai, Houei Sai etc is the capital of the Lao province of Bokèo on the border with Thailand.Ban Houayxay lies on the Mekong River opposite Chiang Khong in Thailand being the northernmost border crossing between the two countries. The two are only connected via ferries. Houayxay is also the endpoint of national road no. 3 which connects China via the border at Boten in Yunnan province and Luang Namtha with Thailand. A bridge to Thailand is scheduled for completion in 2012. 
--Pakbeng
As the halfway point on the Mekong sits midway between Huay Xai and Luang Prabang. As the Mekong was once the only major transport route in the country, Pakbeng developed as an overnight stop for both cargo and passenger ferries. As this route down the Mekong is so spectacular, it remains a popular transport route, and Pakbeng is flourishing. Set in a particularly scenic spot, where the Nam Beng flows into the Mekong (Pak means mouth, and Beng is the name of the river), the town itself doesn't have a lot to offer but a number of guesthouses and restaurants have sprung up catering to backpackers.

Enjoy the sunrise view of Mekong River; take the speed boat to Luang Prabang (5hours). Transfer to hotel for checking, and then you will visit the Pak-Ou caves, where thousands of Buddha statues are stored. Start a city tour visiting Wat Visun, Wat Aham, and the beautiful Wat Xieng Thong, walking along the street, Wat Mai, This afternoon climb Phusi hill to enjoy the view overlooking the city and watch the amazing sunset.

It is the capital of Luang Prabang Province. The current population of the city is about 103,000. The city was formerly the capital of a kingdom of the same name. Until the communist takeover in 1975, it was the royal capital and seat of government of the Kingdom of Laos.
The city is also notable as a UNESCO World Heritage Site.The main part of the city consists of four main roads located on a peninsula between the Nam Khan and Mekong rivers. The city is well known for its numerous temples and monasteries. Every morning, hundreds of monks from the various monasteries walk through the streets collecting alms. One of the major landmarks in the city is a large steep hill on which sits Wat Chom Si.

Today, take a guided tour of Luang Prabang, a UNESCO World Heritage site.  Your guide will pick you up from your hotel after breakfast. Attention: Since buses can not enter into the heart of Luang Prabang, city tour is done by tuk tuk from 10 people (4 people/tuk tuk).

-- Vang Vieng Town
Situated halfway down the long Vientiane to Luang Prabang highway, Vang Vieng has become (for better or worse) the pit stop of Laos. Surrounded by splendid karst scenery and overflowing with activities such as caving and tubing down the river, many weary travellers extend their stay here far longer than originally planned.
For many, Vang Vieng is a highlight of their trip to Laos. If your idea of an ideal night involves scoffing happy pizza and quaffing buckets of lao-lao and coke to a background of infinite Friends episodes, then you're going to absolutely love this place. Vang Vieng has become where backpackers shamelessly indulge in Western food, alcohol, drugs and, yes, American sitcoms. 
The reason this tourist mecca has sprung up is the gorgeous Nam Song river and the magnificent karst mountains lining it. The imposing limestone structures rise up out of the land and run for kilometres, framing the rice fields and lazy river. Stunning at any hour, the mountains are particularly beautiful with the golden pink glow of sunset behind them, the perfect time to sit and have a drink at one of the plethora of riverside restaurants. 

After breakfast we visit around Vang Vieng then keep exclusion trip to Vientiane, on the way we will stop to visit Nam Ngum Lake (Dam) we will take private cruise boat along dam to see local fishermen (lunch on boat) after that we will drive directly to Vientiane on arrival visit Sisaket & Haw Prakeo museum, That Luang Prabang & Sunset at Patuxay Monument (built by China GOV donation) and overnight in Vientiane. 
--Vientiane is the capital and largest city of Laos, situated in the Mekong river. Vientiane became the capital in 1563 due to fears of a Burmese invasion. During French rule, Vientiane was the administrative capital and due to economic growth in recent times, it has become the economic centre of Laos.
The estimated population of the city is 754,000 while the number of people living in the Vientiane metropolitan area (the entire Vientiane Prefecture and parts of Vientiane Province) is believed to be over 730,000. The city hosted the 25th Southeast Asian Games in December 2009 celebrating the 50 years of SEA Games.
The Lao capital of Vientiane sits on the northern bank of the Mekong River facing across to the even sleepier Thai town of Sri Chiang Mai. For many visitors, Vientiane provides the first taste of Lao food, culture and hospitality, and it does not disappoint on any count.Actually pronounced Wiang Jan and translated as City of Sandalwood, the modern name of Vientiane comes courtesy of a bastardised French transliteration. Wiang actually means "fort"  but by all accounts it mustn't have been much of a stronghold, as the original city was overrun on a number of occasions by the Burmese and Chinese, and absolutely flattened by the Siamese (Thais) in 1828, after which the city was abandoned and left to the jungle.
This is one reason why many of the wats in the city are of a relatively young age, and if the road layout strikes you as an inspired affair, thank the French for it -- they laid the whole place out when they oversaw the rebuilding of the city from the turn of the 19th to 20th centuries.

Take the early morning flight from Vientiane to Siem Reap; When you arrival, welcome by tour local tour guide and transfer to check in hotel. 
In the afternoon you will visit "Les Artisans D'Angkor - Chantiers Ecole" the finest Authentic Khmer Arts and Crafts. visit old market that is good local marketin Siem Reap.

While the complex is surely one of the globe's most amazing historical sites, Siem Reap province is also home to an array of other ruins, such as Beng Mealea and Bantaey Srei. So if ancient temple ruins are your thing, this province -- an expansive piece of flat land, covered in rice fields and brush -- must be explored fully. It runs along the north coast of the Tonle Sap, Cambodia's "Great Lake", and north to Oddar Meanchey province. Few visitors get around to the fringes.
The provincial capital of Siem Reap is also a transportation hub, with many people coming through here en route to Phnom Penh, Poipet (the northwest border crossing to Thailand) or by boat to Battambang. Siem Reap's international airport now takes in more tourists daily than the Cambodian capital Phnom Penh. Mass tourism has well and truly arrived to this part of Cambodia.

Banteay Srei or Banteay Srey is a 10th century Cambodian temple dedicated to the Hindu god Shiva. Located in the area of Angkor in Cambodia. It lies near the hill of Phnom Dei, 25 km (15 miles) north-east of the main group of temples that once belonged to the medieval capitals of Yasodharapura and Angkor Thom.[1] Banteay Srei is built largely of red sandstone, a medium that lends itself to the elaborate decorative wall carvings which are still observable today. The buildings themselves are miniature in scale, unusually so when measured by the standards of Angkorian construction. These factors have made the temple extremely popular with tourists, and have led to its being widely praised as a "precious gem", or the "jewel of Khmer art."
--Chau Say Tevoda Temple:
Chau Say Tevoda is a temple at Angkor, Cambodia. It is located just east of Angkor Thom, directly south of Thommanon across the Victory Way (it pre-dates the former and post-dates the latter). Built in the mid-12th century, it is a Hindu temple in the Angkor Wat style. From 2000 to 2009 access was restricted as the temple was under restoration in a project initiated by the People's Republic of China. Chau Say Tevoda reopened in late 2009 and is now fully accessible.
--Banteay Kdei Temple
Banteay Kdei, meaning "A Citadel of Chambers", also known as "Citadel of Monks' cells", is a Buddhist temple in Angkor, Cambodia. It is located southeast of Ta Prohm and east of Angkor Thom. Built in the mid 12th to early 13th centuries AD during the reign of Jayavarman VII (who was posthumously given the title "Maha paramasangata pada"), it is in the Bayon architectural style, similar in plan to Ta Prohm and Preah Khan, but less complex and smaller. Its structures are contained within two successive enclosure walls, and consist of two concentric galleries from which emerge towers, preceded to the east by a cloister.
This Buddhist monastic complex is currently dilapidated due to faulty construction and poor quality of sandstone used in its buildings, and is now undergoing renovation. Banteay Kdei had been occupied by monks at various intervals over the centuries till 1960s.

Visit The Great City of Angkor Thom, which was the last capital of the Great Khmer Empire under the reign of Jayavarman VII. This city is surrounded by a 8 m high wall, each side of the city is 4 km long. It draws a perfect square you access this town through 5 gates; 4 of them represent the cardinal points and the 5th one the Victory Gate was the one leading dir3ectly to the Royal Palace Area.

--Angkor Wat 
Angkor Wat is a temple complex at Angkor, Cambodia, built for the king Suryavarman II in the early 12th century as his state temple and capital city. As the best-preserved temple at the site, it is the only one to have remained a significant religious centre since its foundation – first Hindu, dedicated to the god Vishnu, then Buddhist. It is the world's largest religious building. The temple is at the top of the high classical style of Khmer architecture. It has become a symbol of Cambodia, appearing on its national flag, and it is the country's prime attraction for visitors. 
Angkor Wat combines two basic plans of Khmer temple architecture: the temple mountain and the later galleried temple, based on early South Indian Hindu architecture, with key features such as the Jagati. It is designed to represent Mount Meru, home of the devas in Hindu mythology: within a moat and an outer wall 3.6 kilometres (2.2 mi) long are three rectangular galleries, each raised above the next. At the centre of the temple stands a quincunx of towers. Unlike most Angkorian temples, Angkor Wat is oriented to the west; scholars are divided as to the significance of this. The temple is admired for the grandeur and harmony of the architecture, its extensive bas-reliefs, and for the numerous devatas (guardian spirits) adorning its walls.

--Tonle Sap River
The lake sits only about 15 km south of Siem Reap town. If you take the ferry between Phnom Penh and Siem Reap you will cross the lake and dock at the village of Chong Khneas. There are several ways to see the culture and wildlife of the lake area depending on the amount of time you have and your interest.
Cambodia's Great Lake, the Boeung Tonle Sap (Tonle Sap Lake,) is the most prominent feature on the map of Cambodia - a huge dumbbell-shaped body of water stretching across the northwest section of the country. In the wet season, the Tonle Sap Lake is one of the largest freshwater lakes in Asia, swelling to an expansive 12,000 km2. During the dry half of the year the Lake shrinks to as small as 2500 km2, draining into the Tonle Sap River, which meanders southeast, eventually merging with the Mekong River at the 'chaktomuk' confluence of rivers opposite Phnom Penh. But during the wet season a unique hydrologic phenomenon causes the river to reverse direction, filling the lake instead of draining it. The engine of this phenomenon is the Mekong River, which becomes bloated with snow melt and runoff from the monsoon rains in the wet season. The swollen Mekong backs up into the Tonle Sap River at the point where the rivers meet at the 'chaktomuk' confluence, forcing the waters of the Tonle Sap River back upriver into the lake. 
The inflow expands the surface area of lake more than five-fold, inundating the surrounding forested floodplain and supporting an extraordinarily rich and diverse eco-system. More than 100 varieties of waterbirds including several threatened and endangered species, over 200 species of fish, as well as crocodiles, turtles, macaques, otter and other wildlife inhabit the inundated mangrove forests. The Lake is also an important commercial resource, providing more than half of the fish consumed in Cambodia. In harmony with the specialized ecosystems, the human occupations at the edges of the lake is similarly distinctive - floating villages, towering stilted houses, huge fish traps, and an economy and way of life deeply intertwined with the lake, the fish, the wildlife and the cycles of rising and falling waters. 

After breakfast just enjoy the relaxing morning and 10.00 we check out hotel for the speed boat trip along Mekong River down the way to Vietnam .Visa formalities take about 45 minutes at the border. Continue by river to Chau Doc. Meet our guide and transfer to hotel.
In the rest of the afternoon take a boat to visit the unique farms where fish are bred in wooden cages suspended under floating houses on the river. Continue by boat to visit a village of stilt houses belonging to the Cham minority where colorful traditional textiles are woven on old wooden looms. Return to dry land in time to drive up Sam Mountain for view over the Cambodian border.
Accommodation: Hotel in Chau Doc
--Chau Doc
Bordering Cambodia, An Giang province is best-known for being home to pastel-painted Chau Doc, the closest large town to the Vietnamese/Cambodian border crossing on the Mekong River. Wedged between the Cambodian frontier, Kieng Giang and Can Tho provinces to the south and Dong Thap province to the north, An Giang is a particularly riverine province, with both the Bassac and Mekong Rivers within its boundaries.
The nondescript provincial capital Long Xuyen lies around 50km southeast of the border with Cambodia. Some travellers may find it convenient to pass through here for its transportation connections but there are otherwise few other reasons to stay in the capital.
Chau Doc sits at the junction of a tributary linking the Bassac and Mekong Rivers and the Bassac River itself. An incredibly friendly and bustling little city, it has a colour scheme to match its ambience, with bright pastel hues of green, blue and purple adorning many of the newer shopfronts. If you're arriving here from Cambodia, be prepared for the shock into technicolour paradise. 

We leave hotel early in the morning driving crossing Mekong Delta to Cai Be. From here the group will see the Mekong Delta (“Nine Dragon River Delta). This is special experience of Mekong Delta. We will visit the Candy factory, orchard garden, listen to traditional music and have lunch in the ancient house. We cross the island in the middle of Mekong River by oars boats.
Later in the afternoon, drive to Saigon. Accommodation: Hotel in Saigon
--The Mekong Delta is the region in southwestern Vietnam where the Mekong River approaches and empties into the sea through a network of distributaries. The Mekong delta region encompasses a large portion of southeastern Vietnam of 39,000 square kilometres (15,000 sq mi).[1] The size of the area covered by water depends on the season. The Mekong Delta has recently been dubbed as a 'biological treasure trove'. Over 10,000 new species have been discovered in previously unexplored areas of Mekong Delta, including a species of rat thought to be extinct.

Enjoy a morning drive through typical southern Vietnamese countryside to Tay Ninh Province to visit Cao Dai, a local sect of Buddhism, and join a memorable noon daily ceremony of the Cao Dai followers.
After lunch time back to a historic site of the Vietnam War - the Cu Chi Tunnels, an incredible underground network constructed by the local people and guerillas to survive the war against the American explosive attacks. We can even crawl a part inside the tunnel to understand the living of Vietnamese shoulders during the wartime. Drive back to Saigon in the afternoon, check in hotel and relax. Accommodation: Hotel in Saigon
--Cu Chi Tunnels
The tunnels of Cu Chi are an immense network of connecting underground tunnels located in the Cu Chi district of Ho Chi Minh City (Saigon), Vietnam, and are part of a much larger network of tunnels that underlie much of the country. The Cu Chi tunnels were the location of several military campaigns during the Vietnam War, and were the Viet Cong's base of operations for the Tet Offensive in 1968.
The tunnels were used by Viet Cong guerrillas as hiding spots during combat, as well as serving as communication and supply routes, hospitals, food and weapon caches and living quarters for numerous guerrilla fighters. The tunnel systems were of great importance to the Viet Cong in their resistance to American forces, through which they secured American withdrawal from Vietnam and ultimate military success.
