One highlight of the Costa Rica tour is to visit the national park Manuel Antonio. The nice beaches Playa Espadilla and Playa Manuel Antonio invites for swimming. But also take care, often riptides are dangerous. The last bay is not accessible by high tide and it´s used as nudist beach, even when nudism is not allowed in Costa Rica. On weekends and in the highseason a lot of visitors come to Manuel Antonio, to book your hotel in time may be a good advice.
