Trail Overview

The beginning of the trail sets the tone for this roughly 12-mile run; if you have trouble with this, the rest of the trail might be miserable. This is a one-way trail starting on North Bartlett Dam Road. Once you enter, it is pretty tight and you will most definitely encounter off-camber turns, deep rutted-out mounds, and almost every hill (small or large) has obstacles you should go slow with. This trail will flex out your vehicle, have you on 2-3 wheels a bit, and make you think of tire placement. Aside from the fun on the trail, the surrounding views are breathtaking. You're surrounded by the beauty of the desert with such growth of wildflowers and cacti. You will also run into Bartlett Lake where you can have a snack and dip into the water if you desire.

Expect several tight spots, full articulation spots, large rutted-out areas, and off-camber hill climbs.


In 2005, the Bart Fire led to the closure of the area north of Bartlett Lake Road. After several years and volunteers helping, it finally reopened April 6th, 2024.

trail can be done without needing lockers if you pick the right lines. Nothing really technical just a fun trail
