The swimming in the protected cove off Playa Manzanillo is glorious; on placid days the snorkeling is good too. Horseback riding is quite popular; locals stroll the beach with their steeds looking for customers. Biking, fishing and spelunking through the limestone cave system near Majahua can be arranged through local inns.
Troncones has several world-class surf spots (experienced surfers only). The beach breaks can be excellent in summer, but the wave to chase is the left at Troncones Point. When it’s small, the takeoff is right over the rocks (complete with sea urchins), but when it’s big, it’s beautiful and beefy and rolls halfway across the bay.
