Hedgehog Mountain rises to 3,376 feet in the Sentinel Range Wilderness, climbed via a 5.4-mile round-trip bushwhack from Santanoni Preserve. No marked trail — navigators only — but the open summit ledge offers direct views of Santanoni Peak and the Cold River drainage.
Nearby waters include Deer Brook and Pyramid Brook.
