Estelle Mountain

Estelle Mountain is a summit in the Temescal Mountains in Riverside County and rises to about 2,767 feet with prominent granite rock formations visible across its slopes. The peak stands as a notable elevation in this southern California mountain range.

The mountain formed during the Jurassic and Cretaceous periods and contains granite rock that dates back to these ancient geological times. These formations reveal the long geological history of the Temescal Mountains.

Local hiking communities regularly organize guided tours to the summit, contributing to environmental education and preservation efforts in Riverside County.

To reach the summit, drive via Lake Matthews Drive to Gavilan Springs Road, which provides access to the mountain trailhead. The climb rewards you with views across the surrounding mountain landscape.

Ten unnamed canyons surrounding the mountain drain into Temescal Creek and form a natural water network across the northern slopes. This drainage system shapes the landscape and wildlife patterns of the entire region.
