The San Gabriel Mountains shield the LA Basin from the heat of the Mojave Desert while trapping the city’s hazy smog. The rugged lower slopes are thick with chaparral and V-shaped canyons. Rolling peaks and stately conifers top the high ridges.
Explore the vast San Gabriel wilderness by finding a trail hiking guide that speaks to you. Each guide provides detailed turn-by-turn directions, maps, photos, tips, and factoids so you can focus on fun and staying safe.
