The trail follows the right side of the Rio Frias, crossing to the left on a log about an hour from Puerto Frias, the end of the trek. From this magnificent, glacier carved spot, one can catch a bus into Chile but perhaps the perfect ending is to board one of the catamarans for the leisurely cruise through the fjord-like lakes back to Bariloche. The drier ranges to the east of the frontier and close to Bariloche contain a system of huts that provide all the amenities for a delightful multi-day outing. Most of the walking is above treeline in a very rugged range with fantastic views in all directions. The trek described here is difficult, mainly because of sections that involve serious route-finding and steep snow, but you can string together a much easier hike by choosing only certain huts to visit.
All huts offer easy return trails back to the highway.
Inquire at the CAB clubhouse in Bariloche and then take the local bus to the ski area at Villa Catedral. Either hop on the ski lift or follow the trail to Refugio Frey. Nestled at the entrance to a spectacular basin of soaring rock spires, this hut is typical of all the huts in providing simple lodging, including blankets, meals and refreshments. Next day, climb over the pass following the paint-marked rocks, descend and cross a valley through a lovely forest of beech, only to climb over another pass and ride the scree down to Refugio Jacob. The hut warden likes to feed the local fox, or zorro , for the amusement of the guests.
