Yes, not only do you have to pay entrance to enter the national park, but you must make reservations in advance. During the low season this is not a problem, but during the high season it is important that you book several months in advance. This can only be done online through the offices of the SINAC state and the process can be a bit intense at times. This is another advantage we offer our customers. All the packages we offer already include the entrances not only to the Corcovado, Sirena or San Pedrillo national parks, but also to the island of Caño, which belongs to the same protected area.
