Leaving the towering spires of Angkor Wat for the laid-back riverside charm of Champassak feels like stepping into a slower version of Southeast Asia. Siem Reap is a whirlwind of night markets and ancient history; Champassak is a quiet Mekong village where the river sets the pace. The journey crosses the border from Cambodia into the panhandle of southern Laos.
The route is a favorite with travelers heading for the Bolaven Plateau or the 4,000 Islands after Cambodia. The landscape changes from the flat plains of northern Cambodia to the green, hilly fringes of Laos.
Siem Reap to Champassak by Van
The direct way to make this long journey is a regional van, which saves you from stitching together several local bus legs. On booking platforms, the van costs about $44 (November 2026), and the trip takes from about 8 hours 15 minutes, longer if the border queue is slow.[1]
The van crosses at Trapeang Kriel on the Cambodian side. The Lao checkpoint, Nong Nokkheane, is open from 06:00 to 18:00 and lists both visa on arrival and eVisa.[2]
Expect a few stops for restrooms and snacks. The scenery is rural, with a look at daily life in northern Cambodia, and once you cross into Laos the final stretch leads to the Mekong. The vans are air-conditioned but can feel snug when full, so keep your carry-on small.
