The run starts where the Red Rock Canyon Trail
and Mustard Road
meet. There are a couple of benches to signal the start of the trail.
The majority of the trail is in a very similar environment to the rest of the park. While I was there, the river was dried up and served as the running path, but this could change with wet weather. Try and stay on the path that seems the most traveled. In the final stretch of the run, the rock formations get interesting (see photos).
Cactus spread through out the trail.
