Whilst the beach itself is one of the most popular beaches in the Similan Islands, the dive site within Donald Duck Bay is one of the most popular spots for night diving in the Similan National Island Park. This is mainly as it is easy to get to, it has a very shallow depth with a maximum of around 20 meters, and the bay provides great protection from currents.
The dive site is mainly composed of coral bommies that are on a slope away from the beach and its simplicity makes it a great place to learn how to dive or to undertake refresher courses. Each of the small outcrops of coral, are surrounded by many invertebrates and reef fish. Many visitors feed the visiting Green and Hawksbill turtles and so these have become a common sighting in the area. Many of the dive operators in the region are trying to stop this from happening in order to protect the turtles.
Other marine life includes the normal reef fishes found in the area and as the area is so shallow, divers can spend their time investigating the area and try to find the more difficult to spot marine life such as octopus and cuttlefish. When used as a night dive, divers can easily spot many different kinds of shrimp, crab, and lobster.
