This is a nice little trail system. If you are just hiking up to Knobby Rock, it's a relatively brief and straight forward climb. The sandstone erosion gives the appropriately named overlook its unique, lunar appearance - never seen anything quite like it.

While I can recommend Knobby Rock for children, the loop around the Maze and the Sand Cave is far more technical and potentially hazardous. If approached counter-clockwise (starting opposite from the steps leading up to Knobby Rock) the loop ascends steadily up and along the base of the rock to an even larger formation that comprises the Maze and cave. The former is a labyrinth of corridors which can require some maneuvering. Much of it is dark and I found myself rapping on the rocks to listen for rattlers. The yellow blazes for the trail are particularly helpful in navigating through it. If you have been to the Sand Cave in nearby Ewing, VA, the one here is relatively modest by comparison - neither a cave, nor particularly sandy.

The remainder of the loop is the most challenging part - a very steep descent down the base of the formation along its east side. One would do well to bring a trekking pole and wear boots with suitable ankle support for managing this segment.

Off the radar and worth a look - for the towering hemlocks alone!!

Knobby Rock Loop is a well maintained trail in a nature preserve. The preserve features an old growth forest of huge hemlock trees. The trail up to Knobby Rock has a bit of elevation gain but isn't terribly strenuous. The rock itself is a huge expanse that offers great views. There is another loop, Sand Cave Loop, that can be accessed from near the top of Knobby Rock Loop. Combining these to make a figure 8 loop will increase the trip mileage to about 5.5 miles.
