The river mouth divides the beach into two distinct sections—north of the channel, sand stretches uninterrupted toward distant headlands, while south of the flow, casuarina trees lean over a narrower strand dotted with driftwood logs smoothed by years of tidal action. At low tide, the river cuts a shallow channel across the beach, ankle-deep and warm, where children dam the flow with sand walls that collapse with each incoming wave. The water here tastes slightly brackish, fresh enough that you can rinse salt from your skin but not quite potable.

Wading into the mixing zone, you'll notice the temperature shifts—cool river current wrapping around your legs, then warmer ocean water as you move seaward. The bottom transitions from river sand, fine and gray, to coarser beach sand mixed with shell fragments. Small fish dart in schools through the shallows, taking advantage of the nutrient-rich zone where ecosystems collide. Egrets stalk the river margins at dawn, stabbing at mudskippers and fiddler crabs that emerge when the tide retreats.
The beach operates without commercial development—no jet ski rentals, no banana boat tours, just a handful of local vendors who set up umbrellas and plastic chairs for fifty baht per day. A concrete picnic shelter sits back from the high-tide line, its roof providing shade for families who arrive with coolers and portable grills, filling the air with smoke from grilled mackerel and chicken. By late afternoon, the vendors pack up and you'll have the entire strand to yourself, nothing but the river's constant murmur and the occasional motorbike passing on the access road.
