Parking at the ball fields on Wicklow Dr. is restricted so plan on parking outside the gates or coming in another way other than Wicklow Dr.
Traveling down Scout Trail
you'll intersect with Wicklow Dr. and the Monolith trailhead will be on your right, if you're headed up Wicklow away from the Quarry. This trail is fast and flowing with a few tough climbs added in.
Alternatively, if you head up the Fall Quarry Trail
on the East Side of 95, then head down Monolith and/or Naysayer you'll have a better experience. Most of the features, including the ramp at the bottom all appear better traversed heading downhill.
None of the trails are well marked and there is a lot of erosion going on unfortunately. No real established path up, and most of the trails flow better down.
A top entrance, or a well thought out ascent would make this a great biking destination.
