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.

Where is the Bommer Canyon Trail?

The main trailhead is in Irvine, CA. Use this address:
6400 Shady Canyon Trail, Irvine, CA 92603

Bommer Canyon Trail Directions 3 — The entrance can be easy to miss, look for this sign out front.

Bommer Canyon Trail Directions 4 — The main trailhead parking lot is small and fills up quickly with hikers, locals, and mountain bikers.

Bommer Canyon Overflow Parking — If there’s no parking in the main lot, head down to the Turtle Rock Community Park and then walk up from there.

Bommer Canyon Trail Directions 2 — You shouldn’t have a problem parking at the Turtle Rock Community Park, the lot is huge. There are also bathrooms here.

Bommer Canyon Trail Directions 7 — The main trailhead has bathrooms and water fountains.

Gear For the Hike

This is an easy trail where you can get away with fitness clothes or light hiking gear. Good trail shoes will help on the dirt, and trekking poles can help on the steeper climb at the end. Bring 1L of water. It can get hot in the summer; there isn’t any shade.

The Best All-Around Hiking Footwear
For most hikers, a hiking shoe is the great choice, and the Moab 2 is a winner. The ventilation is great, they last forever, offer good protection, and have a solid grip. There are sizing options for everyone’s foot in this really comfortable and reliable shoe. This shoe is also a favorite of thru-hikers. The only downside is that they are a little heavy. If you are looking for something more aggressive or lighter, check out the bottom of my gear page.

Stay Safe Out of Cell Phone Range
If you’re not familiar with the Garmin InReach technology, it allows you to send and receive text messages where you don’t have cell phone signals. You can also get weather reports and trigger an SOS to emergency responders. Even if you don’t have an emergency, sending a quick message telling a loved one that you’re okay or are running late is well worth the cost. The Garmin InReach Mini (REI | Amazon | My Review) fits in your palm and weighs next to nothing.

Gaia GPS Mapping App
Smartphones are not backcountry instruments, but almost everyone has one today. And they all have GPS onboard. So I recommend getting a good GPS hiking app like Gaia GPS that supports offline maps. Just make sure to put your phone in airplane mode so the battery doesn’t drain. GaiaGPS not only has smartphone and tablet apps, but also an online planning tool. You can drag the GPX hike tracks from my (or any) guides into the online map and they will sync to your phone. You can also check for wildfires, weather, snow, and choose from dozens of map types with a premium membership (HikingGuy readers get up to 40% off here). Note that I also carry a paper map with me in case the phone dies or gets smashed.

Here’s my complete gear list that I personally use, have tested, and recommend, updated April 2021.

How are you going to navigate this hike?
To start, you should always have a paper map and compass. And it helps to print this guide out or save it on your phone. I highly recommend a GPS as well. I use the Garmin Fenix 6 Smart GPS watch ( REI | Amazon | My Review) with maps (or the more affordable Garmin Instinct). The GPS smartwatch is nice because it’s rugged, works if your phone dies, and also has a billion other features like sleep tracking, workout recording, etc.

Hike Brief

Govenor At Bommer Canyon — Here’s how Arnold Schwarzenegger likes to hike Bommer Canyon, in a suit and tie. Photo LA Times

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.”
