This is the Green Loop at the MAC. This loop is much more technical than the Gold or Purple loops. It has a small rock garden, and some fun rock kickers on the descent. Nothing is extremely technical, however. This trail also has some rollers/water bars that are great fun to pump and jump at speed. This trail is also popular with hikers, so be sure to use caution around blind corners.
This is my favorite loop at the MAC, because it is technical enough to entertain even the most advanced rider, while being flowy and fast.
