Ban Chuen unfurls along Khlong Yai's eastern edge in a ribbon of tan sand so long you can't spot where it ends, even from the raised road that shadows the shore. Casuarina trees lean landward, sculpted by monsoon winds, their roots gripping low dunes that crumble into the strand. You park where a dirt track meets the beach and step onto sand that squeaks underfoot, coarse and dry, scattered with cuttlebone fragments and the purple shells of sand crabs. The Gulf spreads flat and pale green, fishing stakes marching offshore in geometric rows that vanish into haze.
“The mainland Gulf beach that shows you Trat's working shoreline, unhurried and unpolished, before it crosses into Cambodia.”

Midmorning heat empties the beach except for a few vendors beneath tarp shelters selling grilled squid and somtam, their motorbikes parked in the casuarina shade. You wade in where a freshwater seep darkens the sand, the water warm as tea and shallow enough to walk a hundred meters before it reaches your chest. Small waves fold over in lazy lines, their foam the color of old lace. A trawler idles past the breakers, its crew sorting the morning catch, gulls wheeling in its wake.
By afternoon the tide retreats, exposing sandbars ribbed like washboards and tidal pools where hermit crabs scuttle between clumps of sea grass. You collect a few shells—nothing rare, just cowries worn smooth—and return to your towel as the sun begins its descent toward the Cardamom Mountains. The beach remains nearly empty, the quiet broken only by the put-put of a longtail heading home.
