Of the 33 public high peaks on the Catskill 3500 Club roster, this is the most inaccessible, and the reasons are underfoot. No trail reaches the summit, so it is a pure bushwhack, with routes starting from the Neversink Fisherman's Path or from the Peekamoose-Table Trail. Denning Road is the trailhead for both, beginning on a yellow-blazed logging road for roughly 1.2 miles before the blue-blazed Peekamoose-Table Trail. The Rocky and Lone loop is the popular way to string the two summits together.
Going Rocky first and then Lone makes a 9.8-mile round trip with 2,155 feet of gain, following the Fisherman's Path for 2.6 miles beside the river before turning uphill. Near the top the spruce and fir grow so thick that pushing through is slow work, and the canister approach runs through dense balsam forest. Blowdown and rocks add to the puzzle.
The summit is little more than some big rocks with no view, though a viewpoint lies just south. The mountain is flanked by Lone to the west and Balsam Cap to the northeast, and its south and east slopes drain toward Rondout Creek and the Hudson. Watch for the footbridge on the descent, because the river deepens downstream.
