The islands were sparingly inhabited by fishermen for centuries, although tourism accounts now for most economic activity. In the Perhentian, the most common activities are scuba diving, sunbathing, and snorkeling. The Perhentian offers detailed diving and draw diving skills. Competition for dives is competitive, though quite cheap, averaging out to RM60-80 per dive depending on how many dives done and a person brings their own gear. There are 5 dive centers on Kecil's Long Beach: Spice Divers, Coral Sky Divers, Sea dragon Divers, Turtle Bay Divers and Sunlight Divers. For Snorkeling, all resorts rent out snorkeling gear (RM30 a day for mask, snorkel and fins) and organize snorkeling tours throughout the islands.

Turtles, are most commonly viewed in the middle of the beach in front of Perhentian Island Resort, where the sandy bottom is covered with algae.
