Trail Overview

This is a gravel forest service road that follows Big Mary Creek. Several walk-in campsites are located just off the trail. There is good fishing and hiking along the trail, and decent cell service in the area. Near the beginning of the trail you'll see a nature camp. Several good swimming spots can also be found along the creek.

Easy trail. Can be accomplished by a stock 4x4. Good hiking trails. Gate blocks the end of the trail. Two good camp sites.

We only saw one other vehicle while on the trail. I would have rated this Trail as a 1. Most vehicles should be able to traverse it without four-wheel drive. About 2/3 of the way down the trail, it is obstructed by the pictured barrier. We walked the dogs about another quarter of a mile up the trail past the sign and let them swim in the creek, which is beautiful by the way. We never saw why it was closed. There was a creek that goes under the road just past the sign so I'm wondering if it is caving in under there.
