Discover more about Grottos Trail

The Grottos Trail, a gem nestled in the White River National Forest just 9 miles east of Aspen on Highway 82 (Independence Pass), offers a concentrated dose of natural beauty and geological intrigue. This easy 0.6 to 1.1-mile loop is perfect for families and casual hikers, showcasing a unique combination of ice caves, waterfalls, and unusual rock formations. The trail begins by crossing a bridge over the Roaring Fork River. Shortly after, you'll encounter the Erratics, large boulders resting on a smooth granite slab, deposited by a glacier that melted approximately 18,000 years ago. A bit further along the path leads to the Grottos themselves, sculpted rocks forming a slot canyon, and often containing ice even in the summer months. Continuing on, the trail leads to the Cascades, a series of small waterfalls along the Roaring Fork River. The area is ideal for a picnic, with tables available near the parking lot. The Grottos Trail provides a chance to witness the power of nature and the beauty of the Colorado landscape.
