After hiking camelback, I was hoping that this trail would be more challenging then it was. We did the loop trail, which was 4.6 miles. You don't have as much of a panoramic view as you do when you're hiking camelback, but the trail is very peaceful for a Sunday afternoon. This is more of a relaxing hike than a exercise hike. It's a good running hike, since you don't have much of an incline, but be careful of all the rocks and unsteady gravel. There are a lot of cacti here, I bet it would be amazing to come here when they bloom. Anyway, I became bored halfway in with nothing much to look at, but the start of the trail is really cool.
You have a map of the mountains and the types of routes you can take. Also have a lot of information on the preserve.
I would return to do a run, but not to hike. It's a good hike for a newbie though!
