Big Ring Map

While Big Ring is most often used for cross country or trail riding, since it’s located in the bike park and connects to many of the downhill trails, Big Ring often forms an exit or ending to many downhill or enduro runs. Despite being a two-way trail, well-built berms and rolling grade reversals help riders maintain speed and flow.


The soil is classic Mammoth Mountain, consisting of dry, loose, dirt and sand between rough volcanic rocks. Despite the intermediate rating, rocks still appear in the trail tread and remind you that yes, you’re still riding a mountain bike!

Most of the trail rolls along beneath towering pine trees, but beautiful views of the valley open up where the singletrack crosses the exposed ski runs.
