Kep & Kampot Province

Kep and Kampot provinces occupy the southwestern corner of Cambodia where the Cardamom Mountains meet the Gulf of Thailand. The landscape shifts abruptly from forested limestone hills to a coastline of mangrove-fringed estuaries, rocky headlands and shallow bays. Kep itself was a French colonial beach resort from the 1900s, its villas long abandoned to jungle vines after the Khmer Rouge period, giving the town an eerie layered quality — ruined modernist concrete behind palm groves, fishing boats at the market pier, and blue water beyond. The Kep Crab Market is the dominant food institution: blue swimmer crabs cooked with Kampot pepper, sourced from the cage traps visible in the bay at low water. Tidal range in the Gulf of Thailand here is modest, typically 1.0 to 1.5 m on spring tides, with a mixed semidiurnal pattern — two unequal pairs of highs and lows each day. The shallow gradient of the bay floor means that even a moderate ebb exposes wide mudflats, useful for the crab farmers who check their traps on foot. Kampot, 25 km north by road, sits on the tidal Kampot River, which carries brackish water several kilometres inland on spring floods. The old French quarter sits on the eastern bank; the pepper-farm hillsides of Bokor rise to the west. River kayaking and evening boat cruises on the Kampot River are the primary water activities, timed around the flood tide that pushes calmer, clearer water upstream. The outer island Koh Tonsay (Rabbit Island) off Kep is a day-trip destination with calm beaches and basic bungalows. Predictions for this coast come from Open-Meteo Marine (gridded model, ±45 min / ±0.2–0.3 m).
