Hike Western Mountain Loop
What to Expect
Safety Advisory
The Perpendicular Trail's granite steps get dangerously slick when wet. After rain, the moss-covered stone becomes a skating rink — trekking poles and shoes with aggressive tread are essential, not optional.
Several sections include iron rungs and a ladder bolted to rock. Dogs are technically allowed on leash, but this trail is a poor choice for most pets — the steep steps and metal hardware make it stressful for animals and owners alike.
Trail Details
- 1
Run this loop counterclockwise to ascend the Perpendicular Trail rather than descend it — going down those steep granite steps with tired legs is a recipe for a twisted ankle.
- 2
Park at the Long Pond pumping station trailhead on the south end of Long Pond. It fills up far slower than east-side lots, and you can usually grab a spot even on peak summer mornings.
- 3
Pause halfway up the Perpendicular Trail to look back through the ravine — the view of the stone steps cascading below you through the moss and birch trees is the most photogenic moment on the entire loop.
