If you'd prefer not to climb Collierstown Road (Route 770) as shown in the Longdale Furnace North Mountain Loop
Featured Ride you can drive to a small parking area at the start of this trail. Just take caution driving as it's a one-lane road with little room for turnoffs. Having said that, let's get to the fun!
Just south of the small lot at the top, you'll discover the trail, which heads south along the ridge. Welcome to instant fun and incredible views! If you want to plan your vista detours well, a hiker's guide to the trail with detailed distance markers (by Jeff Monroe) can be found here
The views are phenomenal and the ridge, in my opinion, ought to be ridden back and forth as much as you're able to get the most out of your time! Lots to see and lots of fun to be had!
Near the end of the ridge climb, you'll have to hike-a-bike up stone steps through Pete's Cave (a conglomeration of enormous stone outcrops that form an eery, but awesome cavernous route up and over to continue the trail). At the end of the ridge to the south, you should come straight up to an old wooden sign that says "TO LONGDALE."
After a super fun, winding descent down the ravines and about five to six distinctive creek crossings (no bridges needed with low crossing water), you should see a sign directing you to the right to connect with Simmons Road (FSR #334) to follow the winding gravel service road that leads you back to the lower parking lot. Otherwise you can keep left on the North Mountain
Trail proper to work down to the Yaccrs Run Trail (#658) where it meets Tri County Road (FSR #271).
I rode this solo, but strongly urge you to ride this in a group. It would have been a lot more fun and safer as a group or partner ride. Marked as 'Commonly Bikepacked' as there is a campsite and is navigable as a portion for a bikepacking route.
