Beautiful hike along the coast. So far, this was the first hike that could be done without a guide and without an entrance fee. While snorkeling at Playa San Josito, we saw moray eels, many small fish, and a sea turtle.

San Pedrillo is ideal for visitors seeking rainforest experiences, hiking, river walks, and birdwatching. The station offers beautiful nature trails and diverse scenery, but sightings of large mammals are less frequent than in other park sectors. Many expectations arise from spectacular wildlife videos â in reality, such encounters are rare. Visitors to San Pedrillo should focus on experiencing nature rather than expecting guaranteed wildlife sightings.

A wobbly suspension bridge that you cross when you take the beach hike from Drake Bay to San Josecito. But it's also a nice photo spot.

Best to check the tides, and plan your visit accordingly. At high tide itself, that part of the beach becomes inaccessible.
