I rated this trail 4 stars because it could use some improvements, like directional signs and maps. And a lot of broken glass on the ground. Other then that the trail is awesome. A great combination of dirt, slickrock and a little sand. Breathtaking views of Billings below.
I went to the right from parking until houses, turn around and kept riding along the edge of the cliff.
Was a bit tricky to find where trail crosses Zimmerman Rd.
After I passed Airport there was a nice descent into Billings. There trail must continue but I didn't find it. So, this out-and-back was around 14 miles. There's even more trail after the houses but I hadn't enough time to explore whole thing.
Overall super fun trail and will ride it again (with full-suspension bike).
