This is a tough climb or a fast technical descent. The theme of this trail is very rocky. The top two miles traverse a constant supply of rocks with lots of twists and turns and a few small (6-8") ledges. As you start to see more dirt and leave the rocks behind, it will get a little steeper downhill prior to meeting up with Lower Sugar Loaf.

      Super cool downhill, not sure why TF suggests going uphill... it'd be kind of miserable the other way.

      Super fun downhill. Pretty rocky and technical. Would be tough uphill.

      We hope you've been enjoying Trailforks!
