Pakse serves as the logical third destination after experiencing Vientiane and Luang Prabang. This city of approximately 90,000 residents sits at the confluence of the Xe Don and Mekong rivers in southern Laos, functioning as the capital of Champasak Province. Founded by French colonizers in 1905 as an administrative center, Pakse lacks the architectural heritage of Luang Prabang but provides access to the Bolaven Plateau, pre-Angkorian temples, and the Four Thousand Islands region. The city operates primarily as a transit hub where travelers arrange onward journeys rather than as a destination for extended stays. Direct flights from Vientiane take 90 minutes on Lao Airlines, while buses cover the 677 kilometers in 10 to 12 hours on Route 13. The Japanese-funded Pakse International Airport opened in 2009 and handles limited international connections to Bangkok and Siem Reap alongside domestic routes.
Wat Phou stands 40 kilometers southwest of Pakse near the town of Champasak. This Khmer Hindu temple complex predates Angkor Wat by at least two centuries, with construction beginning in the 5th century and continuing through the 12th century. The site received UNESCO World Heritage designation in 2001. The temple originally honored Shiva before conversion to Theravada Buddhist use in the 13th or 14th century. The main sanctuary sits at the top of a 100-meter climb up the lower slopes of Phou Kao mountain, with water channels carved into bedrock feeding ceremonial ponds below. Stone lintels show Hindu deities including Vishnu, Shiva, and Krishna, while Sanskrit inscriptions date various structures. The lower pavilions, causeway, and baray reservoir follow the mountain-temple cosmology seen in later Angkorian architecture. February hosts an annual three-day festival coinciding with Makha Buxa that draws pilgrims from across southern Laos and Thailand. Songthaew trucks depart Pakse's morning market for Champasak town between 8:00 and 15:00, covering the distance in one hour for 25,000 kip. From Champasak, tuk-tuks reach the temple entrance in 15 minutes.
The Bolaven Plateau rises east of Pakse to elevations between 1,000 and 1,350 meters, creating microclimates cooler than the Mekong lowlands by 5 to 10 degrees Celsius. French colonists established coffee plantations here in the early 1900s, and arabica and robusta coffee remain the primary cash crops across the plateau's approximately 10,000 square kilometers. The town of Paksong serves as the plateau's commercial center, located 50 kilometers from Pakse via Route 23. Multiple waterfalls punctuate the plateau's edges where rivers drop from the basalt highlands to lower elevations. Tad Fane Waterfall splits into twin streams plunging 120 meters into a forested gorge within Dong Hua Sao National Protected Area. The waterfall runs strongest from July through November during and immediately after the monsoon season. Tad Yuang drops 40 meters in a single curtain accessible via a short trail from the road, with a pool deep enough for swimming during high-water months. Coffee farms throughout the plateau offer tours showing processing from cherry to roasted bean, with the harvest occurring from November through February. Motorcycle loops covering the plateau's waterfall circuit, coffee farms, and ethnic villages typically require two to three days from Pakse. Guesthouses in Paksong and near major waterfalls provide basic accommodation between 60,000 and 120,000 kip per night.
Si Phan Don, the Four Thousand Islands, occupies the Mekong River where it spreads across a 14-kilometer width near the Cambodian border, 140 kilometers south of Pakse. The river fractures around permanent and seasonal islands, with the largest inhabited islands being Don Khong, Don Det, and Don Khon. The area supported fishing communities for centuries before French colonizers built a railway and bridge connecting Don Det and Don Khon in 1897 to bypass the Khone Phapheng Falls, transporting goods between steamboats operating above and below the rapids. Remnants of the narrow-gauge railway and a rusted French locomotive remain on Don Khon. The Irrawaddy dolphin population in the Mekong near Don Khon numbered approximately 80 individuals as of a 2020 survey conducted by the World Wildlife Fund, down from an estimated 200 in 1997. Early morning boat trips departing between 6:00 and 7:00 from Don Khon increase sighting probability, though dolphins range across several kilometers and sightings are not guaranteed. Khone Phapheng Falls, 15 kilometers southeast of Don Khon, ranks as Southeast Asia's largest waterfall by volume, with the Mekong dropping 21 meters across multiple cascades spanning nearly 10 kilometers during peak flow. The falls prevent upstream navigation, historically marking the limit of French river commerce from the sea. Buses and minivans depart Pakse for Nakasang, the mainland pier for Don Det and Don Khon, throughout the day between 8:00 and 15:00, completing the journey in 3 to 3.5 hours. Boats shuttle passengers from Nakasang to Don Det or Don Khon in 10 minutes.
Don Det and Don Khon developed backpacker infrastructure beginning in the mid-1990s, with guesthouses constructed on stilts over the river and along interior paths. Room rates range from 50,000 kip for basic fan rooms with shared facilities to 200,000 kip for riverside bungalows with air conditioning. The islands lack motorized vehicles except for a small number of utility motorcycles on Don Khong, creating an environment dependent on walking and bicycles. Bicycle rental costs 10,000 to 20,000 kip per day from guesthouses and shops. The bridge connecting Don Det and Don Khon charges a 35,000 kip fee for non-residents to cross into Don Khon, collected at a checkpoint on the bridge. Small restaurants along the river serve Lao staples including larb, tam mak hoong, and ping kai alongside adapted Western breakfast items priced between 15,000 and 40,000 kip per meal. Khao piak sen appears on menus throughout the islands as a breakfast soup containing thick rice noodles in pork or chicken broth. The slow pace and limited activity options suit travelers seeking rest after more intensive portions of Laos itineraries, with most visitors spending two to four nights before continuing to Cambodia or returning north.
That Ing Hang sits 15 kilometers northeast of Savannakhet city, a 16th-century stupa rebuilt multiple times after damage from Siamese invasions and weather. The monument attracts pilgrims especially during the annual festival in January or February based on the lunar calendar. Savannakhet, Laos's second-largest city with roughly 125,000 residents, preserves more French colonial architecture than Pakse due to its importance as a colonial administrative center from 1893 onward. Two-story stucco buildings with shuttered windows and arcaded sidewalks line the older streets near the Mekong riverfront. The city serves travelers crossing to Mukdahan, Thailand via the Second Thai-Lao Friendship Bridge opened in 2006, or those transiting along the East-West Economic Corridor connecting Vietnam's coast to Thailand. Dinosaur fossils discovered in Savannakhet Province since the 1930s led to the establishment of a small museum displaying partial skeletons and information about Cretaceous-era finds, though the facility lacks comprehensive labeling in English.
