Bureau of Land Management, California.
Encompassing 154,000 acres, including just over 100,000 acres of already congressionally-designated Wilderness, Sand to Snow National Monument is an ecological and cultural treasure and one of the most biodiverse areas in southern California, supporting more than 240 species of birds and twelve threatened and endangered wildlife species. Home to the region?s tallest alpine mountain that rises from the floor of the Sonoran desert, the monument also will protect sacred, archaeological and cultural sites, including an estimated 1,700 Native American petroglyphs. Featuring thirty miles of the world famous Pacific Crest National Scenic Trail, the area is a favorite for camping, hiking, hunting, horseback riding, photography, wildlife viewing, and even skiing.
The sandy part of Sand to Snow is accessible at the Whitewater Canyon Preserve area within the monument - the turnoff for Whitewater Canyon is five miles west of Palm Springs on Interstate 10. Take Whitewater Canyon Road five miles north to the trailhead. To visit the snowy parts go to Forest Falls and a short hike on the Vivian Creek Trail. To reach the trailhead, continue west on I-10; take the exit to Yucaipa and follow State Highway 38 north, then east to Forest Falls.
