    This trail is amazing and offers plenty for everyone. Some steep climbs and descents. very beautiful ridge riding from both loops. There are some sweet swithbacks on the back side of the Bollinger Canyon Loop Trail. Just watch out for cattle. They can get angry at times.

    on this side the trails are mostly firetrails. follow the map and you can connect to the singletracks on the east side of the ridge.

    some singletrack is hidden on bollinger side, but you really have to know what you are looking for
