Prospect Rock Professional Guide
Detailed Trail Description from our Guidebook
"Begin hiking on the State Line Trail and ascend 0.25 mile before turning right (houses are still in view here). For the next 0.25 mile, the trail uses log steps to prevent erosion. At mile 0.75, the Ernest Walter Trail (yellow blazes) heads left. This trail makes a loop around Surprise Lake and West Pond. After 0.1 mile, the State Line Trail turns sharply left and then right. For the next 0.4 mile, the trail heads west, crossing over the ridge of Bellvale Mountain with several short ascents and descents.
At mile 1.2, the State Line Trail joins the A.T. at the New York–New Jersey state line, heading north on the A.T. 0.1 mile to good western views from open rocks. After 0.25 mile, there is a trail register on a pine tree to the right of the trail, and 0.5 mile after joining the A.T. (following a short climb), you will reach Prospect Rock (elevation 1,433')."
