Site Information

History and Use

Established in 1979 to protect lowland forested areas and to connect Piedras Blancas National Park & Corcovado National Park.

Areas of Interest

The Hwy 245 bridge crossing the Rio Rincon is well-known as a reliable site for the endemic Yellow-billed Cotinga, as well as Panama Flycatcher, Turquoise Cotinga, and the endemic Mangrove Hummingbird.

Birding in the village of Dos Brazos (near Bosque del Rio Tigre) reportedly offers the opportunity to find Double-toothed Kite, Scarlet Macaw, Striped Cuckoo, American Pygmy Kingfisher, Red-rumped Woodpecker, and White-necked Puffbird, and along a nearby small stream even White-tipped Sicklebill.

Bosque del Rio Tigre offers superlative birding in relative luxury, and may well be the best place to find Osa specialties that are usually elusive and retiring. Birders not staying there may reserve morning guided bird walks.

Access and Facilities

The most accessible portions of the Reserve are traversed by Hwy 245 from Chacarita to Puerto Jimenez. Lodges in the area include Bosque del Rio Tigre, & Esquinas Rainforest Lodge (both highly regarded birding destinations), Suital Lodge (near Mogos), and Danta Corcovado Lodge (near La Palma). Other possible choices might include El Mirador Osa and Ventana al Golfo, both near Mogos.
