La Cangreja National Park, National park in Puriscal Canton, Costa Rica.

La Cangreja is a national park in central Costa Rica that protects dense tropical forest across multiple elevation zones. The protected area features waterfalls, streams, and interconnected hiking trails that lead through different forest types.

The area was first protected in 1984 under Law No. 6975, and in 1987 Decree No. 17455-MAG made it the Cerro de la Cangreja Protected Zone. Executive Decree No. 30479-MINAE of 5 June 2002 turned it into La Cangreja National Park, covering 2,519.23 hectares. Since 1988, Puriscal residents, now the Ecotrópica Foundation, have worked with the government and volunteers to protect it.

The name comes from the 1,305-metre Cerro La Cangreja, whose several side ridges look like crab legs when seen from the air. An indigenous story tells of a great crab that blocked villagers' route to other settlements until a warrior cut off one of its legs; defeated, it turned to stone, which is why the summit is rocky.

The park is best reached by private vehicle and features multiple well-marked trails of varying difficulty levels. Bring sturdy hiking boots and rain gear since the forest terrain is often wet and slippery.

The only place on Earth where Plinia puriscalensis grows, a tree that bears its fruit pressed against the trunk. The park also holds 44 endemic plant species among roughly 1,000 recorded, and its flora is richer than that of Corcovado National Park despite the smaller area.
