Rạch Vẹm is a working fishing village on Phú Quốc's northern coast, approximately 25km from Dương Đông, where the island's mangrove-fringed coast faces the Gulf of Thailand and the distant Cambodian coastline. The village consists of simple wooden stilt houses built directly over the sea - each with a fish cage below and a small boat for daily inshore fishing.
It is one of the last stretches of Phú Quốc that looks the way the whole island did before large-scale resort development, and as of 2026 it faces rezoning pressure that may transform it significantly in the coming years. Offshore from the village, Starfish Beach (Bãi Sao Biển) is a shallow tidal flat where large numbers of Protoreaster nodosus - red horned sea stars up to 30cm across - congregate in clear water of 30-80cm depth, visible without snorkeling gear.
