The Cham Islands are an archipelago of 8 islands located a few kilometers off Hoi An, on the central coast of Vietnam. Among them, the small uninhabited island of Hon Tai is one of the most popular with snorkeling tours. Crinoids, hard and soft corals, giant clams and starfish can be seen on the reef that fringes the island’s northern shore, which many tropical fish call home.

How to get to Hon Tai snorkeling spot?

To go snorkeling in Hon Tai, you’ll have to book a snorkeling tour with a local operator. While most tours depart from the mainland (mainly from Cửa Đại Beach), it may be worth spending a night or two on Cù Lao Chàm, the largest island in the archipelago, easily reached by ferry from Hoi An.

From there, you’ll fully enjoy the island life and you will easily organize private tours of the surrounding snorkeling spots with local guides.

Hon Tai snorkeling exploration tips

Most tours take snorkelers on the reef that borders the northern coast of Hoi Tai. The depth is on average 10ft/3m above the coral, but varies depending on the distance with the island.

The reef is quite damaged but hosts an interesting diversity of organisms, including hard corals (mainly massive coral decorated with Christmas tree worms), leather corals, sea lilies, and giant clams.

The presence of crown-of-thorns sea stars, which feed on coral, probably explains the average health of the reef ecosystem. Blue sea stars are also common at this location.

A decent diversity of fish can be spotted at reef, including oval butterflyfish, eightband butterflyfish, sergeant majors, two-lined monocle bream and a few small groupers.

Underwater visibility is most of the time decent at this location, but may decrease significantly depending on the weather and currents.
