Hon Kho lies just off Nhon Hai fishing village. The water around it is remarkably clear, making it the area's favourite snorkeling spot.

In the low-water season a sand-and-rock path emerges between the waves, letting you walk out toward the island between two walls of sea.

Back in the village, try the fresh seafood and the local specialty: squid banh xeo. Galaxy Hotel can arrange tours and transport — call/Zalo 0909 287 343.
