Hardeep Wreck is the famous Samaesarn wreck of the SS Suddhadib, a WWII-era steam cargo ship lying on its starboard side in deep water and offering a classic historical wreck dive with marine life settled across the structure. It suits advanced divers who want depth, wreck atmosphere, and a more serious profile than the area’s shallow reefs, with the site’s identity rooted in both its wartime history and its mature artificial-habitat feel.
