White sand beach koh samet

Koh Samet’s “White Sand Beach” is Sai Kaew Beach — the island’s signature strip of powder‑soft sand and clear, swimmable water on the northeast coast. Longtail boats and speedboats idle just offshore while beach bars line the sand under palms and casuarinas. At the northern end, the Mermaid (and the child) Monument marks an easy photo stop; at the southern end, Sai Kaew Beach Resort anchors the bay with loungers and a steady holiday hum. Daytime is simple: swim, sun, and wander barefoot between cafés for fruit shakes and grilled seafood. The sand really is talc‑fine and the drop‑off is gentle, so it works for first‑timers and families as much as couples escaping Bangkok for the weekend. It’s roughly a one‑kilometer sweep, so you can find a patch to yourself on weekdays even when the middle section gets lively. After sunset the vibe flips. Restaurants drag tables onto the beach, and fire dancers spin up the night — the nightly show outside Ploy Talay is the classic crowd‑pleaser. Grab a front‑row seat, order a cold beer, and watch the sparks fly with your toes in the sand. Practicalities: Sai Kaew sits near the island’s northern tip, a short songthaew ride from Na Dan Pier, and it’s part of Khao Laem Ya–Mu Ko Samet National Park. Weekends and Thai holidays run busier; midweek evenings feel pleasantly lazy. Last checked March 2026.
