Chollinco Airport (ICAO: SCIF) is a small general aviation airstrip located near Llifen, a rural village situated on the eastern shore of Lake Ranco in the Los Ríos Region of southern Chile. The facility primarily serves private aircraft, light planes, and occasional charter operations accessing the remote lake district. The airport has no scheduled commercial airline service and operates at a minimal infrastructure level, typical of private rural airstrips in Chilean Patagonia. It serves as an access point for tourists, landowners, and lodges in the surrounding lake and forest wilderness area. Llifen and the surrounding Lake Ranco area are known for fly-fishing, ecotourism, and outdoor recreation. The airstrip provides a practical alternative to long overland journeys through mountainous terrain, making it a valued asset for the local community and visiting travelers.
