View gigantic icicles that tower 150' above the Ausable River and a chasm blanketed in snow (as conditions allow). Descend into the depths of the chasm to explore the rock and ice formations along the popular Inner Sanctum Trail (only available with guided tour). When conditions allow, self-guided admissions are allowed along the Rim Trail only. To guarantee chasm entry for your visit we highly recommend reserving one of our two-hour guided tours today! During these tours, a guide will take you down on the Inner Sanctum trail while going over the history of the beautiful chasm.
All visitors must wear snowshoes or ice cleats for safety, depending on how much ice and snow has accumulated. Rentals are available for per day if you do not have your own.
Due to the nature of winter hiking and equipment required, self-guided tours are limited to children age 8 and up, and guided tours are limited to children age 10 and up.
