The Town of Ramapo recently purchased this land in order to save it from development. The Friends group of Sloatsburg's Harmony Hall has begun working with the NY/NJ trail conference in order to make an official trail up to this beautiful landmark. Although there are several ways to access the rock, this "trail-in-progress" is the best way to go. You will find the head of this trail to the left of the Sloatsburg Senior Center building on Liberty Rock Rd in Sloatsburg. The center is across from the Sloatsburg Public Library and behind the Super Seven gas station ... There is plenty of parking both on the hill by the senior building and below it across from the library. The trail is marked with LR markers. The cache itself is off the beaten path, but very accessible.
I recommend accessing this cache during the day, as it is almost always peaceful, quiet and muggle-free. Unfortunately, it seems to be a huge "party spot" at night. You will find several fire circles built around the area, and you are almost guaranteed to find an obscene number of empty beer cans and other discarded objects...such a shame. A little CITO would be great if you're so inclined! :)
Congrats to Walkin' Ed FTF! :)
