The Kep Archipelago is so small and scattered that many of its islands can barely be found on a map. Set in the Gulf of Thailand, this chain shelters what once was thriving coral reefs, seagrass meadows, and mangrove forests that supported turtles, rays, reef fish, and countless invertebrates. But heavy overfishing and illegal operations have plagued the region. While there's life rebounding, it's hard and long work being pushed forward by conservation teams.
Near the Cambodian–Vietnamese border, Koh Ach Seh is as much a battleground as it is a sanctuary. This remote island has become a hub for renegade conservation—where patrol boats head out daily to intercept illegal trawlers crossing from neighboring waters. Around the island, restored seagrass beds and reefs are starting to breathe life into the shallows, attracting turtles, rays, and reef fish back to the area.
