Sirena Ranger Station is where you will find the ranger station headquarters and is the heart of the Corcovado National Park. Located right on the coast, you can stay overnight at this station before continuing on throughout the rest of the park. This is the hardest station to get to, but well worth it for those who take the time to make the trip. La Sirena to La Leona is a hot 16 kilometers beach hike that takes 7 hours to complete. Timing is important here because of the tide and also for the heat. This trail passes through rocks on the shore that can be crossed at low tide or else there is another trail that goes inland that is parallel to the beach, and that provides more shade. Beware of the Crocodiles at tide crossing and for extended hikes it is recommended going with a guide.
