Playa Biesanz
For a less turbulent swim and smaller crowds than at other Manuel Antonio beaches, head to this quiet beach within a sheltered cove. There are a few tidepools near a cluster of rocks and, during low tide, you can see fragments of turtle traps dating back to AD 900, when the area was inhabited by the indigenous Quepoa people. You can rent snorkeling gear for $15 and kayaks for $35. Prepare to pay $2–$5 to the unofficial parking attendant who monitors cars. You're likely to see monkeys and butterflies on the trail connecting the road to the sand. Amenities: none. Best for: snorkeling; solitude.
