Cabo Blanco is very important for seabird protection and one of the most scenically beautiful areas on the Pacific coast. Evergreen species predominate more in its forest, although they are mixed with deciduous species as the spiny cedar (Bombacopsis quinatum), the most abundant tree with specimens over 40 m high. Other species of large trees commonly seen along the path are the sonzapote (Licania platypus), the silk cotton tree (Ceiba pentandra) which can grow as much as 60 m high, the cotonron (Luehea seemannii) and the camibar (Copaifera camibar), which is not found elsewhere on the peninsula. There are 150 tree species in the reserve.
Also not very numerous, the fauna is quite varied. Apart from tree squirrels (Sciurus variegatoides) which are found in large numbers, there are agoutis (Dasyprocta novemcinctus), white-nosed coatis (Nasura narica), howler monkeys (alouatta palliata) and white-faced capuchins (Cebus capucinus).
There are a lot of seabirds, particularly brown pelicans (Pelecanus occidentalis), magnificent frigatebirds (Fregata magnificens), ospreys (Pandion haliaetus) and brown bobbies (Sula leucogaster). The colony of the latter species, with approximately 500 pairs, is the biggest in the country. Along the coast within the reserve there are three brown pelican roosts where no les than 250 birds retire every evening. The total bird population in Cabo Blanco include around 150 species.
Cabo Blanco Island, situated 1.6 km off the coast, is a piece of rock with its vertical walls, scarce grassy vegetation, some bushes and a lot of guano, which constitutes an unassailable refuge for seabirds. The Cabo Blanco end is made up of an extensive rocky platform with countless tidal pools where large numbers of small marine organisms live. The marin portion contains very diverse fauna, queen conches (Strombus galeatus) and lobsters (Panulirus sp.) occur in large numbers. Near Colorado Beach and the El Sueco path, Pre-Hispanic archaeological remains have been found.
Cabo Blanco is at the southern end of the Nicoya Peninsula. It can be reached from Nicoya via Paquera-Cóbano-Montezuma-Cabuya (152 km), or from Puntarenas by ferry via Paquera-Cóbano-Montezuma.
Two path start from the park offices. The El sueco path leads to Cabo Blanco Beach and the el Danés path makes a complete circle of the forest. At the offices there is a picnic area with tables, toilets, drinking water and soft drinks. There are boats between Puntarenas and Paquera and buses between Paquera, Cóbano and Montezuma. In Cóbano, Montezuma and Cabuya, there are hotels, restaurants and grocery stores, and in Montezuma, taxis can be hired.
