Trail Information

Highlights

This trail is a great distraction from the nasty traffic coming home from Las Vegas. If your sitting in gridlock near this point on the 15, exit at Oak Hill Road and hit up this trail. This is a short trail that, under the right circumstances, actually might get you home a little faster. 3N45 bypasses the peak of the Cajon Pass from Mariposa Road and comes out on Highway 138 which will take you back to the 15 at the Cajon Junction. When traffic on the 15 is stopped, this trail will get you moving again. That is, as long as the trains don't stop you. You will cross over two and under one train track as you near Highway 138. The trains that run this route are long and and slow. If they stop you, get comfortable, but most of the trains coming through here will be on the middle track which you can drive right under.

Short trail, fun in the wet. Great way to get by pass the traffic on 15. Might not save a lot of time, but you'll have a lot more fun taking this route than staying in stop and go traffic

Excellent way to scenically bypass some of the I-15. If you can, visit Hill 582 for a respite. Watching the trains go through the pass without the views of the highway is very relaxing. Fun place to bird and wildlife watch as well.
