Highlights of this site include a pretty swim-through on the western side at around 18m, while the eastern slopes feature a large garden of staghorn coral, locally known as Fantasea Reef. This suffered coral bleaching a few years ago but is still worth a visit. To the south-east of the island is a rocky pinnacle which starts at 14m and drops down to 30m. This is easily visible in good conditions, and is frequently visited by big schools of snapper, barracuda, trevally and other pelagics.
All the usual reef life, including reef fishes, eels and crustaceans can be found at Koh Bida Nai, and even turtles have been known to make an appearance. Shark sightings are not uncommon either - timid bamboo sharks can be found hiding away in the cracks, and black-tips and leopard sharks can be spotted in the sandy patches around the island.
