“An out and back hike in one of the richest bio-diverse areas in Southern California.”

The Boulder Loop Trailhead at the Northeast end of the parking lot is a widely used trail. Once through this area you'll hit multiple junctions that lead to various parts of the Plateau trail system with many leading to dirt access roads. Follow trail signs while keeping left, leading to the Grande Vista Trail
. Along this trail you'll find Tenajas, pockets in the stream beds created by water rolling back into itself when met with these large boulder in its path, all of which create ecosystems found nowhere else. You'll cross seasonal streams over well maintained foot bridges leading to open space grasslands bordered by Engelmann Oaks and wild flowers in the spring. When clear, you can see Mt. San Jacinto and Mt.San Gorgonio to the east. In the mornings and evenings, Mule Deer can be seen skirting the tree lines and also coyote racing across the trails ahead of you. Birds, bugs, reptiles, and more can be found year round. This is a jewel of an area and we're very fortunate to have it.
Flora & Fauna
Engelmann oak woodlands, riparian wetlands, coastal sage scrub, chaparral, bunchgrass prairie, and vernal pools as well as more than 200 species of native birds and 49 endangered, threatened or rare animal and plant species, including mule deer, mountain lions, badgers, bobcats, western pond turtles, white-tailed kites and fairy shrimp. Of the two species of fairy shrimp that live in the seasonal vernal pools on the Reserve, one is found only here and nowhere else on Earth!
