Refugio Huayna Potosi is the perfect starting point to climb the Huayna Potosi the 6,000 m mountain that's closer La Paz. The refuge is at 4,700 meters, and can be reached by car, so we only" have 1300 meters to climb. When I was there in February, temperatures were higher than usual, so that the layer of snow and ice that you need to cross to reach the summit was very unstable and inclines were suspended for tourists. But it's worth the climb to the top to see the Andes amazing landscapes and to practice ice climbing. The shelter is modern and comfortable, and the walks around the area are very pleasant. It's managed by the agency of the same name, Refugio Huayna Potosi, the owner, Hugo Berrios is one of the most prestigious Bolivian climbers.
Ice climbing at the Huayna Potosí is recommended for novice ice climbers because the guides the agency uses are very good and able to get someone like me up a 15 meter wall even though I'd only done it one other time in my life, with little success. It's a day-long journey. The agency leaves Peace at 8 a.m., and in less than two hours you'll be at the 4,700 meter refuge, which is where you equip yourself for the ice climb. Then you walk for an hour to the practice area, where they teach you how to handle an ice ax, crampons, as well as using ropes and knots, things about crevasse rescue, etc. It's very interesting and instructive.
