Located in the Cleveland National Forest in California.

The Agua Tibia Wilderness is in the northern portion of the Palomar Ranger District, east of Temecula and south of State Route 79.

The Agua Tibia was established as a wilderness on January 3, 1975. This 15,934-acre area is mountainous and cut by many deep canyons containing only intermittent streams. Vegetation is mostly chaparral with oak woodlands and some coniferous forests at the higher elevations. Elevation ranges from 1,700 feet in the canyon bottoms to the 5,077 foot Eagle Crag Peak at the southeast corner. Small pools of water in the canyon bottoms become warm in summer months and thus the name Agua Tibia—Spanish for warm water. Summer temperatures may exceed 100 degrees in the canyons and on the slopes, but are a moderate 80-90 degrees at upper elevations. Rain averages 25 inches annually and falls usually from January through April. Snow falls on upper slopes occasionally. The best time to hike is late autumn through midspring.

Agua Tibia has 25 miles of trail. Trail layout and map information can be obtained from the Vail Lake and Pechanga USGS 7.5 minute topographic maps. Trailhead parking is provided just after you turn off Highway 79 before entering Dripping Springs Campground. Here are some highlights. . .
