Trail Overview

The Thomas Hunting Grounds Trail (1N12), often also referred to as the Morton Peak Trail, is an easy dirt road that takes you from the chaparral and shrubs of Mill Creek to the oaks and pines of the San Bernardino National Forest before dropping you in the town of Angelus Oaks. The Thomas Hunting Grounds themselves offer yellow post sites for dispersed camping, and the Santa Ana River Trail offers hiking for those interested in traveling by foot. Pay attention and be mindful of others as this road is popular for hiking and mountain biking as well as 4x4 and dual sport riding.

Difficulty

Easy dirt forest service road. Clearance and good tires make 4wd mostly unnecessary in dry conditions however use caution in the winter months and after heavy rains when this road should only be attempted with 4wd. Road is suitable for rigs of all sizes with ample places to pass.

Super dry, a little tight from over growth so if you’re adverse to pin-stripping and have a full size may want to wait. Otherwise nice easy trail. Great views and lots of wildflowers right now. Some campsites and a little picnic area closer to north end of trail towards Hwy 38.

Easy trail for a beginner. My stock frontier made it very easily in 2wd only. Great views and a great trail for someone getting into off-roading. Also some people were hiking so be careful.

You can tell trail has been groomed. Easily doable in any 2wd suv, maybe even a regular car

Started from Mentone to yellow post sites. Found multiple people camping with no closed signs posted. Trail was very clear no obstructions.

We went all the way to the campground but the ranger was there saying heavy equipment was coming down. Said he wouldn’t fine us but he could. Not sure when it opens again.

Beautiful trail, very easy, any 2wd with suv clearance would be just fine. Couple miles into the trail you will drive through a burned area that lasts a few miles. Doesn’t really look too nice, but does give off a cool eire/mysterious vibe. Rest of the trail is beautiful with scenic views all around.

Trail gave away to a pretty bad washout about 2.75 miles up from the 38

It was an easy trail with nice views. It went from a charred landscape to lush forest. We seen a fox and a deer while on the trail which was cool.
