Encrusted with colorful corals and home to various fish, it's a beautiful and relatively easy wreck to explore. For a more challenging dive, the Inthara is a larger freighter that lies on its side at around 24 meters. Divers can explore its holds, engine room, and even the captain's cabin, encountering crustaceans, eels, and schools of fish that have made the wreck their home.
