The Bommer Canyon Trail, a natural oasis nestled within suburbia, offers a little bit of everything. This easy hike showcases natural beauty, has lots of wildlife spotting opportunities, an interesting history, and sweeping vistas as you approach the highest point in the San Joaquin Hills. The full 4.8 mile hike includes some uphill, but if you want to do something easy, I'll show you an easy 2 mile option that's flat and great for families. Bommer Canyon is a National Natural Landmark and California's first Natural Landmark; it's worth visiting.

Hike Brief

- You'll be hiking through the San Joaquin Hills, which were once underwater, but have now been pushed up from tectonic action. When the 73 Toll Road was built (which you see at the end of the hike), they actually unearthed 5 million year old fossilized whales.
- Bommer Canyon was part of a Mexican land grant. When the Americans took over, the Irvine family eventually acquired it.
- Bommer Canyon became the center of the Irvine cattle ranching operations, called "Bommer Canyon Cattle Camp." Every spring all the cattle that roamed over what is now the greater Irvine area were gathered here in a roundup. The cattle camp remained in operation for almost 100 years (1870s-1970) until the Irvine family realized that there's more money in real estate than cows.
- The entire Irvine Ranch area became a National Natural Landmark in 2006, and then the first California National Landmark in 2008, when Arnold Schwarzenegger hiked here as part of the designation ceremony. The Natural Landmarks Program "recognizes the conservation of sites that contain outstanding biological and geological resources."
