We rented a car in Arequipa to drive to Cabanaconde and the Colca Canyon. (Great trip! But the road from Chivay to Cabanaconde was rough, to say the least.) This reserve was just along the route and we stopped several times to take photos of vicunas. When we stopped for views of volcanos, the altitude was 4910 meters, or 16,100 feet....something we weren't prepared for! My son and I got massive headaches from the sudden increase in altitude. Although we got to lower altitudes in Chivay and Cabanaconde, around 11,000 feet, it's still enough to make you light headed and head-achey. Be prepared!
