Denman Mountain is the most southerly of the Catskill 67 peaks. At 3054′ it dominates the southwest view from the Red Hill fire tower. The mountain has a snowmobile trail that runs along its base and much of the land is owned by the DEC and is part of the Sundown Wild Forest. However, the summit is privately owned and if you wish to stand on its highest point you’ll need landowner approval. With that said, Denman is one of the close enough peaks as you can climb to 3015′ on DEC land which leaves you about 40′ below the top. One could hike the ridge up directly from the parking area or extend the hike by exploring the snowmobile trail before making the climb to the summit. Denman is ranked at 88th highest in the Catskill 100 and 53rd of the Catskill 67.
Close Enough Peak but still on Private Land
Even though we have determined that this mountain is a close enough peak, the actual summit is on private land. If you wish to stand on the highest point you must get the landowner’s permission.
