North America > Central America > Costa Rica > South Pacific Costa Rica > Osa Peninsula > Corcovado National Park
While the park is one of the more remote in the national park system, Corcovado provides excellent wildlife viewing opportunities.
- The park was established on October 24, 1975.
Flora and fauna
National Geographic called Corcovado National Park the "most biologically intense place on Earth" and this is no exaggeration. All four of the monkeys species found within Costa Rica (Mantled Howler, Squirrel Monkey, Spider Monkey and White-faced Capuchin) exist in large numbers throughout the park. Two crocodilians (the occasionally large and saline tolerant American Crocodile and the small Spectacled Caiman) persist within all of the park's major waterways, as do Bull sharks. The Jaguar population within the park is the healthiest in all of Central America, however it is still extremely unlikely for a visitor to spot one (most locals have never seen them either.) Many other elusive cats call the park home as well, including the Puma (which is slightly smaller and more arboreal in Central American than in the United States, probably due to competition with the Jaguar,) Ocelot, Jaguarundi and Margay. The park is one of the last strongholds of the Baird's Tapir and there are hundreds within decent proximity from Sirena Station, usually found lounging in the shade or in shallow pools of stagnant water. There are dozens of snake species present, many of them venomous, including the Fer-de-lance (also known as terciopelo or "Costa Rican landmine",) the Bushmaster, the Eyelash Pit Viper, and the Coral Snake. The largest snake within the park is the non-venomous Boa Constrictor. Numerous other small mammals and reptiles are common within the park including, but by no means limited to, the White-nosed Coati, Sloth, Tamandua, Giant Anteater, Basilisk, and Ctenosaur. Birds include the highly endangered Scarlet Macaw, the Tiger Heron, Black Vulture and the Chestnut-Mandibled Toucan, among hundreds of others including the critically endangered Harpy Eagle.
- Dry season. Running from mid-December until mid-April with occasional rain showers.
- Wet season. Running mid-April until mid-December.
Travel to and through the park is perilous and is best accomplished during the dry season.
On February 5th, 2015 a new trail into Corcovado was opened in Dos Brazos de Rio Tigre. Sendero El Tigre is the most accessible trail into Corcovado as it is possible to travel to and walk in one day. The trail is 5 miles/8 kilometers long and takes between six to eight hours; depending upon walking speeds and time taken to stop to view wildlife. Dos Brazos is 7.5 miles/12 kilometers from Puerto Jimenez and can be reached by taxi or bus. The cost for this trail(guide included) is $125 for two people, which includes the $30 entrance fee to the park. Reservations can be made directly with the tourism office of Dos Brazos by calling (+506) 8323-8695 or via email which can be found on the Dos Brazos website.

Permits must be reserved in advance. You must have a permit to stay overnight at Sirena. In practice, the Park often allows campers with their own food to enter without advance reservations and prepayment, but during busy times of the year even the camping areas are filled, especially Sirena Ranger Station. Sirena is the only ranger station that offers dormitory lodging and hot meals in addition to camping. La Leona, San Pedrillo, and Los Patos offer only camping with no food service. It is possible to secure park permits directly from the Ranger Station in Puerto Jiménez, but they do not accept credit cards, so it requires passing through Puerto Jiménez and a trip to the bank to make the payment or costly international wire transfers. Note that the Park Service (MINAE) does not issue park permits more than one month in advance of anticipated arrival.

- Camping is possible only at the ranger stations at the entrances and at the central ranger station. Sirena station is a series adjoining structures connected by covered walkway. A covered platform next to a kitchen area and restroom provides needed shelter for pitching free standing tents and mosquito nets. As the platform is covered, you do not need to bring a fly if you are bringing a tent. Showers are available.
- Backcountry camping is not permitted within the park due to the fragile ecosystem. Outside of the park it is permitted and an attractive option for adventure trekkers looking for something more than a nice tidy three day park trip. See http://www.soldeosa.com/editorial/01-15-2011-serpent.htm for a windy description of an out of park trail that dovetails nicely into a multi-day park trip and provides a deeper perspective into Osa history, since this route was originally the route between Carate and Jimenez for those that could not afford to charter a bush plane.
- Drinking water. The water at the ranger stations is supposedly potable, but it is highly advised to bring some sort of portable water purifier or sterilizer as it is unrealistic to cart all of your own water in. Be especially careful while hiking from La Leona to Sirena Station- the park recommends the bare minimum of 1.5 liters but at least 3 liters is safer. Dehydration and heat exhaustion can and do kill very quickly.
- Sunscreen. The walk from La Leona to La Sirena is very exposed and it is very ill-advised to not wear proper protection.
- Bugspray. Malaria is not a concern in Corcovado, but Dengue fever is a possibility.
- Buddy or Guide. Stay safe, walk as a team. The river crossings are often underestimated and can be especially dangerous for solo hikers.
- Avoid swimming. The ocean tides in this area are extremely powerful, while crocodiles and bullsharks are present in both the Rio Claro and Rio Sirena. River crossings should be done quickly and carefully. NEVER risk crossing either of these rivers at high-tide or during stormy weather. Caimans may be present in all rivers and streams but are not considered a threat to humans.
- Snakes. There are Fer de Lance and various other poisonous snakes here. Fer de Lance or Tercioepelo, as it is known locally, is most active at night commonly along stream beds.
- Nature's defenses. Be careful of trees covered by thorns, spines, or ants.
- Peccaries Also known as Javelinas. There are two different species of peccaries in Corcovado, the Collared and the White-lipped Peccary. They run in packs and can be very aggressive. If threatened by a group of peccaries, climb a tree until you are six feet or higher off the ground.
- Emergencies. Park officials all own short wave radios and there is a pilot on-call. There are landing strips at Drake, La Sirena ranger station, and in Puerto Jiminez. There is also a local doctor in Drake.
- Maps Best maps locally are given out by the rangers, and are hand-drawn and not to scale. You may want to bring your own topo. However, topographic maps are neither required (the few trails are clearly visible) nor useful (almost impossible to find out where you are on the topographical maps).
The reason Corcovado is so amazing is because it has been so remote and a conscious decision to keep it beautiful is required.
- Carry out all trash and waste and leave no trace.
- Please pick up any trash you see that was left inside the park.
- Encourage others to do the same.
