Bueng Khong Long

Bueng Khong Long is a large freshwater lake straddling Bueng Khong Long and Seka districts in Bueng Kan province, part of a wetland system recognised internationally as a Ramsar Site since 2001. The Thai government first protected it as a non-hunting area back in 1982; the Ramsar listing that followed covers roughly 2,214 hectares and around 33 species of wintering migratory waterbirds, alongside nationally vulnerable fish. There’s no general entrance fee for the lake itself, and no permit: a non-hunting area bans hunting rather than restricting visitors.

The water is shallow, 0.5-1 m over most of the lake with a few deeper pockets. Five small islands sit in its northern third, where the floating and emergent vegetation is thickest, and Don Sawan island holds the site office.

Local fishermen run long-tail boats that double as informal tours, heading out across open water to birdwatching spots and, when the season’s right, patches of lotus blooming along the shallower edges. It’s a working lake as much as a nature site. The same boats that carry visitors are used for fishing, and the fishing itself is part of what the Ramsar designation protects, since the wetland is also a spawning ground that sustains the local subsistence catch. Shoreline paths offer a slower alternative if you’d rather walk than take a boat, following the reed-lined banks where herons and kingfishers are commonly seen.

November through February is the main birdwatching window, when the wintering migratory species the site is known for are present in the largest numbers and the weather is at its coolest and driest for the northeast. Outside that window the lake is quieter: fewer birds, but also fewer visitors, and the fishing-village side of the experience is still there year-round.

Insider Tip: Arrange a boat through a local operator in the lakeside villages rather than trying to find a formal ticket booth. There isn’t one, and word-of-mouth or a guesthouse recommendation is the more reliable route to a fair price.

Watch out: Facilities are minimal outside the boat-launch points and the Don Sawan site office. Don’t expect marked trails or English signage. Older write-ups, including some Ramsar documents, list the lake under Nong Khai: Bueng Kan only became its own province in 2011.

Phu Thok, the striking sandstone mountain with its exposed-ridge monastery walkways, makes a contrasting stop elsewhere in Bueng Kan province.
