Trail Information


1N34 San Sevaine Road is located in the beautiful San Bernardino National Forest. The trail runs east to west on the south-facing slopes between Mount San Antonio (Mt Baldy) and the Cajon Pass. The views into the Inland Empire are spectacular where you can spot the ocean on a clear day. This trail has somewhat unusual seasonal closures to protect important fawning habitat for mule deer, a Forest Service Management Indicator Species. You will not find this trail open between March 1st and Labor Day. Another highlight of this trail is the Joe Elliott Yellow Post Site near the end. Joe Elliott was the Superintendent of this forest from 1929 to 1935. Southern California's largest conifer tree was also at this campsite, 23 feet in circumference and 140 feet tall but had to be taken down for safety reasons.

I noticed they closed the gate a couple weeks ago just after the heavy rainfall. I assume there was a mudslide/landslide somewhere along the trail. Hopefully it reopens soon before March 1 so we can enjoy it before the seasonal closure begins.

Not sure if the trail is open, I’ve come twice and the gate at the entrance is locked! 😞

Difficulty Accuracy: Spot On

Really good views. The trail is 2wd with traction tire doable for sure. Icy once you get to waypoint 9. We turned around since there was a 100' stretch that was a sheet of ice.
