This is the Red Loop at the MAC. This trail has a enjoyable climb, great views of Yucca Hills Road, and some fun, banked switchback turns. There is one rock kicker partway through the descent that is rollable, but very boostable if you hit it at speed. The builders knew what they were doing. All the trails at the MAC are expertly built. They are fun for and flowy for beginners, and feature some challengeable gap jumps for advanced riders.
We hope you've been enjoying Trailforks!
