The Cranberry Bog trail runs under a series of attractive rocky shelves on the south side of the Elm Ridge. It's best to begin this trail from the Mid-Mountain trail. You'll start with a quick descent on some steep switchbacks.
Afterwards, the trail levels out and you follow it for a while until you reach the Elm Ridge Trail
, where you can climb back to the to the top of the ridge.
You can also park at the Peck RD lot and ride this and mid mountain up the hill.
