Upper Whistle Punk is a fast but technical trail. It's both playful and challenging.
The route starts by rolling out on tight trail sandwiched between huge tree stumps. The tread is techy, interspersed with roots and rocks.
The first descent transitions to a series of quick ups and downs over playful, off-camber sections before rising up into a small opening in the trees on a short flat section. From there, Upper Whistle Punk dives back into the forest and the main part of the descent.
This is where the trail drops off and gets steeper and faster. After a big left hand carving bermed turn, the route continues down quickly over large rock gardens, armored roll-downs and through tight tree/root gateways. Every so often there's a roller or table jump to mix it up.
