This group of sites sits in the Andaman Sea off Khao Lak in Phang Nga Province, with boats departing from Thap Lamu Pier. The collection spans both ocean and freshwater diving: the Boonsung and Bangsak wrecks are former tin mining dredgers that now serve as artificial reefs, drawing large schools of snapper, trevally, and fusiliers alongside lionfish, nudibranchs, frogfish, and occasional blacktip sharks. Cheow Lan Lake adds a contrasting technical freshwater dimension, with caves, walls, and drop-offs reaching considerable depth. All sites are boat-access only and suit beginners through to intermediate divers, depending on the site chosen.
