Twin earns its name from a pair of summits along the Devil's Path: the higher sits at the northwest end, and a lower one lies roughly half a mile to the southeast. The trail runs between Indian Head and Sugarloaf, dropping through Jimmy Dolan Notch on one side and Pecoy Notch on the other, so both directions bring real scrambling.
Most hikers start on Prediger Road and take the southeastern approach, which begins level and then turns steep enough to need hands. The first major outlook appears before the summits and shows Indian Head, Overlook, and the reservoir. The southern summit is the prize: a wide ledge gives roughly a 225-degree view over the Ashokan Reservoir and a long line of ridges, best on a clear morning. The north summit has a smaller ledge with a fine view of its own. Between them, expect steep rock, chimneys, loose stone, and deep mud.
Rain falling here drains three ways, toward Schoharie Creek, Saw Kill, and Beaver Kill, all of which end up in the Hudson system. The peak sits inside the Indian Head Wilderness, where camping above 3,500 feet is prohibited from March 21 to December 21, and where bears share the forest with hikers. Dense balsam fir covers much of the high ground.
