The best diving areas are Roca Pelícano, the sea-lion colony off Land’s End, and the reef off Playa Chileno, at Bahía Chileno east of town. Tio Sports at Playa Médano is one of the largest water-sports outfitters, but there are numerous alternatives.

Surprisingly good snorkeling can be done right from Playa del Amor, swimming left, toward the marina. A mask, a snorkel and fins should run about M$200 per day. Panga rides cost about M$200 for a round-trip if you bargain directly with a captain. Tipping is expected.
