Los Burros Professional Review and Guide
"The Los Burros trail begins at the Los Burros Campground, 7,900 feet up, and climbs to 8,300 feet. Cool to cold year-round, this is the White Mountain area’s must-ride adventure. The ride starts out with some easy climbs, long, lazy singletrack through meadows, rock gardens, and three moderately hard climbs.
Once past the first steep climb, there’s an insanely fast (remember IMBA rules) downhill. The singletrack roller coaster that wraps around Wishbone Mountain (the mountain the trail goes around) about three-quarters of the way into the ride makes the whole trip worth it ... but don’t expect to have lots of energy left over. Los Burros is a physically demanding ride, especially if you’re used to lower altitudes. Trail Surface: Mixed singletrack and doubletrack."
