Laguna Parrillar National Reserve, National reserve in Magallanes Province, Chile.

Laguna Parrillar National Reserve covers 20,814 hectares about 52 km south of Punta Arenas, reached via Route 56 and a 30 km turnoff at the Agua Fresca police checkpoint. Its centrepiece, Laguna Parrillar, is the main water reserve for Punta Arenas. The reserve protects lenga and Magellanic coihue forest, with calafate and michay shrubs, and is the habitat of the huemul, puma and black woodpecker.

Laguna Parrillar National Reserve was created on 22 April 1977 by Supreme Decree No. 245 of the Ministry of Agriculture, under Chile's military government. It was established to protect native species at risk of extinction and to safeguard the 970-hectare watershed of the Parrillar lagoon, the main water reserve for Punta Arenas. CONAF administers it.

The reserve takes its name from the Parrillar lagoon, which supplies drinking water to Punta Arenas. Its 970-hectare basin was the reason for protecting the area. Visitors today use the reserve for sport fishing, guided hikes and camping, and the two trails are named Chorrillo Hermoso and El Nono.

Access is via Route 56 south from Punta Arenas, turning right at the Agua Fresca police checkpoint at km 25; about 30 km of gravel road leads from there to the entrance, roughly 53 km in total. The reserve closes entirely from May to September. Two trails are open: Chorrillo Hermoso (1,540 m) and El Nono (1 km).

The reserve's waterways shelter native coipo and Chilean otter, alongside introduced beaver and muskrat. In summer look for culpeo foxes and waterfowl such as coscoroba swans and ibis; the reserve receives few visitors each year.
