Trail, Potomac-Garrett State Forest

No reservation needed

Not on Maryland DNR's list of parks requiring day-use reservations as of 25 June 2026.

A natural labyrinth of house-sized sandstone boulders, moss over every surface, with passages narrow enough to turn sideways for. It isn't a signed DNR trail and it isn't on the state forest's map. Locals know it, and that's mostly how you find it.

House-sized boulders with passages between them narrow enough to turn sideways for, and no sign anywhere telling you it exists. The moss holds water for days, so it's slick long after the rain stops. Not one to rush, and not one to do in trainers.

From people who were there

  • The trailhead is a small parking area on Snaggy Mountain Road, near where it meets Cranesville Road. The walk in runs through open hardwood with heavy fern cover before it reaches the boulders.

    Bears on: trailhead, parking, approach

First-hand and useful, but not the same as the agency confirming it — so it doesn't change the stamp below. It changes what I go and ask.

Field notes

What I saw on the day. Not checked with anyone, and it can go out of date faster than the facts above.

  • Field note · 3 August 2026 · Matt

    The trailhead is a small pull-in on Snaggy Mountain Road near Cranesville Road. No sign, so you are looking for the parking area rather than the trail. The walk in is open hardwood with fern up to your knees, and then the ground turns to boulders fairly suddenly. Some of the passages are barely shoulder-width and everything is mossy, which means slick long after it has stopped raining. Not one to do in a hurry.
