Because the reefs are so shallow you can see a lot when you're snorkeling, the colours are bright and you can watch many tropical fish species going about their daily business. This also means that you don't have to swim right up to the shore where a stray fin kick can damage the coral. There's more information about Nha Trang's dive sites and the local marine life on the diving pages.

All of the dive operators take snorkelers on their boats so there are no problems if you're on holiday with a diver. A half day trip will cost around $10-15 for equipment, lunch and transport to the harbour and you can get in the water at two different sites. As with scuba diving, all the trips are in the morning due to local regulations and you can expect to be back in Nha Trang between 1 and 2pm. There's more information about Nha Trang dive centres on the diving pages.
