The Great Boulder likely has the best problem at High Ridge, Expectations. This is the first significant boulder you will see from the approach.

Park at High Ridge Park in Laurel, MD. (N39 06.843 W76 51.769) Walk along the paved path until you encounter a gazebo. Head straight down the hill until you find a path along the river. Head right and cross a small runoff stream, the path heading a little uphill. Walk 5 mins and cut left into the woodline towards the water. If you see houses, you've gone too far. Looking downhill from the ridge, the Great Boulder should be visible. Make your way down to the rocks and enjoy.

After crossing the runoff stream and climbing the hill, follow the high visibility reflective blazes on the trees. The blazes eventually cut left into the woods and down the hill, turn right once you get down the hill and you'll soon encounter the Great Boulder.
