This dive site, Waterfall Wall, is a very good wall dive with many different marine species to spot hiding amongst the coral wall. Found in the Racha Yai area is a dive with an average depth of around 20 meters. The visibility is superb and often is greater than 30 meters. The current is moderate to strong but the dive is relatively easy and so divers of all levels can complete the dive. All divers should be careful of the current as it can switch directions very quickly, leaving divers going in the opposite direction to their planned dive.

The dive site is a steep wall that quickly drops down to the ocean floor. It is covered with many hard corals and it is home to many groups of schooling fish. The coral is mainly made up of staghorn corals, although there are also some anemones.

Divers who arrive in the early morning will be able to spot larger fish such as barracuda, jacks, mackerel, and tuna. Leopard sharks and stingrays are also common morning swimmers. There are many different types of reef fish to be found here including butterfly fish, angelfish, groupers, snappers, and parrotfish. Boxfish, schools of yellow tail barracuda, and big-eyed trevally are also residents of this great dive site.
