Bueng Kluea

Hook

Bueng Kluea, nicknamed the “Sea of Isaan,” is a roughly 7,500-rai freshwater lake in Selaphum district, Roi Et, with a genuine white sand beach along its western shore — an unusual sight this far from any coast. It sits over an old underground salt deposit that gives the lake its name, though the water itself is fresh year-round. Entry is free, and it’s open daily from 08:00 to 17:00.

Experience

The main draw is the roughly 1 km stretch of white sand on the western side, wide enough that from the shoreline the lake genuinely reads as a beach rather than a pond — hence the “Sea of Isaan” nickname among Thai visitors who come here without traveling to an actual coast. The water is shallow near the shore and used for swimming and simple water recreation, with floating raft restaurants anchored along the bank serving Isan dishes — grilled fish, som tam, sticky rice — in the open air over the water.

The lake’s name comes from a stranger detail: during the dry season, salt crystals form on the exposed banks from a deposit sitting beneath the lakebed, and locals have collected and boiled that salt for household use for roughly two centuries. It’s a rare inland salt phenomenon in a province otherwise defined by rice paddies, and it’s the reason the lake carries “kluea” (salt) in its name despite never tasting of it.

Atmosphere & Timing

Weekdays are quiet, mostly locals fishing or eating at the raft restaurants. Weekends bring more visitors from around Roi Et for a swim and a meal, and the lake functions as an informal spot for watching waterbirds along the quieter shoreline stretches. Shade is limited out on the sand itself, so plan around the middle of the day if you’re sensitive to sun.

Insider Tip: Go for a late-afternoon meal rather than a midday swim — the raft restaurants are at their best a couple of hours before closing, with the day’s heat easing off and the lake at its calmest.

Watch out: There’s little natural shade directly on the sand beach, and the “sea” nickname can create expectations of clear blue water — it’s a functional freshwater lake, not a resort beach, and facilities are basic.

Practical

Bueng Kluea is in Bueng Kluea subdistrict, about 10 km east of Selaphum town and roughly 40 km from central Roi Et. From Mueang Roi Et, take Highway 23 through Thawat Buri to Selaphum, then Highway 2259 toward the lake. There’s no direct public transport, so a car or motorbike is the practical option — a taxi or hired driver from Roi Et town works if you don’t have your own transport.
