Trail Information


4S05 - Mellor Ranch OHV is just one of the many trails that make up the 4x4 off-road network west of Idyllwild. It is located in the San Bernadino National Forest and it is rarely closed. Mellor Ranch is a designated OHV trail, so use caution and be prepared to share the road. You will see pine, fir, and cedar at the higher elevations, in addition to the typical Southern California sage, mesquite, manzanita and scrub oak as you descend to the west end, you will also have outstanding views to the west-southwest.

Easy trail. Trail as advertised. There was an abandoned, gutted minivan with quite a few bullet holes at the end of the trail.

Did this trail with my small hatchback AWD on a stock rims and suspension with All terrain tires. Easy trail for beginners and for stock AWD/4X4 vehicles. This trail will lead you to a few different off road trails. I started from the Hi-way 243 from the gate of 4S05 and ended up all the way to 4S10 road.

Recently graded, easy drive, lots of flowers today. Narrow in places, tons of blind corners, PLEASE go slow. Took it to 5S09 towards Pine Cove, then it got even more narrow, and harder. Not too bad for an above average 4Runner and it's crew of two...

Drove in from Hwy 243 today and a little after Waypoint 2 there was a large boulder that appeared to have broken off and fell into the road blocking it for anything but small vehicles. I had to back up a ways and then turned around
