Fun outer loop. Starting from the west end, the trail drops downhill through a series of tight switchbacks. At the bottom, the trail climbs out of the woods and finishes with views of the Front Range. Take a right and loop back onto Bonanza or stay left and connect to Pick-n-Sledge.

Trail should absolutely be a black, lotta sections you’ll be walking across or really struggling through.
Drops to tight switchbacks, rocks trying their hardest to rip your derailleur off or pop a tire and then a long climb at the end. Highly recommend taking bonanza instead.

Borderline black trail as the switchback section is similar to Sluicebox. Best direction is Clockwise (West to East) since the switchback section is a fun descent and would be very difficult to climb. Typically less crowded than the other trails at Apex but still fun!
We hope you've been enjoying Trailforks!
