British owned and operated Siam Adventure Divers began operations in Khao Lak in the early 2000's. Customer service and hospitality are important objectives and the company has adapted to accommodate various styles of activities in the water and offers flexibility with budgets and travel plans.

Siam Adventure Divers offers both day trips and liveaboard safaris. There are two speedboats and a larger comfortable cruising to take snorkellers and divers to such sites around Khao Lak and the west coast. Liveaboard trips on the Similan Jazz are to further destinations such as the Similan Islands, the surin Islands and the Mergui Archipelago.

A range of PADI courses are conducted at the centre and out in the water from recreational and specialty courses to courses at the professional level.
