The Hua Hum Pass is one of the lowest passes of the southern Andes at 685 meters above sea level, which means that unlike other nearby Chile-Argentina passes it never closes due to snow fall and is open year-round. The pass is used primarily for tourism as the Chilean
203-CH road is interrupted by
Pirihueico Lake. A
ferry equipped to transport vehicles as well as people may be taken to
Puerto Fuy, on the other side of Pirihueico Lake. The ferry ride lasts approximately 2 hours. It is the main pass of the Chilean
Los Ríos Region to
Neuquén Province in Argentina. The main cities on both sides of the pass are
Panguipulli in Chile and
San Martín de los Andes (45 km from the pass in Argentina). ==External links==
