An awesome trail! Very, very scenic (be sure to take a camera). Some areas of challenging terrain, with some great short, steep climbs. The coolest thing about this trail is knowing you briefly touch the same path that Butch Cassidy and the Sundance Kid used to escape the law. Now THAT is cool! Overall, Casto Canyon was my second favorite trail in Utah with Goosebery Mesa being my favorite. There is also a small diner down the road from where you enter the trailhead that serves great pasta...think about it, an excellent ride with friends folllowed with a killer pasta dinner. Now it doesn't get any better than that! Make the trip, you'll love it!
