Upper & Lower Plunge trails (aka Sunnyside trail)

Dogs Off-leash

E-Bikes Not Allowed

Upper Plunge and Lower Plunge are two steeper trails connected by a few seconds of climbing on Red Mountain Rd. The Upper Plunge was rerouted in 2018 to include grassy meadows in aspen forest, some rocky ledges and some big fast turns. The upper alignment retains a rocky section that drops down a tunnel of dark timber forest. At the top of Lower Plunge, you'll also find an intersection with the Hummingbird Trail. Neither Upper or Lower is recommended for uphill bike travel.

Access Upper Plunge from 4 Corners Rd. / Red Mt. Rd., and then continue on Secret Trail before turning left for the fast drop down Upper Plunge. Lower Plunge is often ridden as a fast and rocky descent when paired with a climb up Hummingbird Trail to create a shorter loop down to Hunter Valley North.

In 2021 the very lowest portion of Lower Plunge was rerouted out of a rutted meadow to provide a longer wander further down valley along aspen groves and through rock gardens. The eastern bottom spur was also rerouted and lengthened to become the East Lower Lower Plunge, to connect directly to the uppermost bridge across the Hunter Creek.
