[1] It is named for its most prominent feature, Cerro Chirripó, which at 3,820 m (12,530 ft) is the highest mountain in Costa Rica.

[5] Summiting the peak begins with a hike along a 16.5 km (10.3 mi) uphill trail from the town of San Gerardo de Rivas to the park ranger's refuge in the Los Crestones sector; that is followed by a 5 km (3.1 mi) walk to the peak.

This last event, however, affected over 20 km2 (7.7 sq mi) of vegetation and forced the administration to close the park for four months.

[8] Part of the Turberas de Talamanca Ramsar site, designated in February 2003, is located within this protected area and shared with Tapantí National Park, Los Quetzales National Park, Macho River Forest Reserve, Vueltas Hill Biological Reserve and Los Santos Forest Reserve.
