La Sirena is an airstrip and biological station deep within the Corcovado National Park. There are dorms, a small camping area, and meals by reservation. The camp is only a few minutes walk from a vast wild beach with tide pools.
Visits
- 2009-02-25: After a night at Los Patos and a breakfast of crackers, we started the arduous hike across the peninsula to La Sirena. Fortunately, the hike was mostly shaded or we might have died from exertion. We stopped to swim in every crocodile infested river that we could find! By the end of the day, I had drunk over a gallon of water. We barely arrived in La Sirena in time for dinner. This species list includes the hike from Los Patos in addition to a full day spent at the La Sirena station.
