Kayaks can be rented on the beach for leisurely paddling for around 200B per hour. Snorkeling trips around the island are popular and you can sign up for a group tour with any hotel or with any of the many beachfront travel agencies for as little as 600B per day. To hire a longtail boat for a half-day private trip, expect to pay around 1,200B.
Scuba diving is quite popular here, too, and Phi Phi Scuba (tel. 07561-2665; www.ppscuba.com), among other full-service, professional outfits, offers anything from day trips to multiday adventures, as well as all the requisite PADI course instruction. Alternatively, try Visa Diving (tel. 07560-1157; www.visadiving.com) on the main strip just east of the ferry pier. Check the websites for prices.
Cat's Climbing Shop, at Tonsai Bay (tel. 08178-75101, mobile), runs rock-climbing trips around the gnarled cliffs of the two Phi Phi islands; prices run around 1,000B for a half day, 1,500B for a full day.
If you feel like a real adrenaline rush, you can sign up with a tour operator to go cliff jumping (jumping off a cliff into the sea), Phi Phi's latest craze, but be prepared to end up with a dislocated shoulder, broken back, or worse, and don't expect the operator's insurance to cover the damages.
