Fall River, in Rocky Mountain National Park, pours into a narrow roadside gulch to form Chasm Falls. To get to the trailhead, take the Fall River entrance located on US 34 / Fall River Road in Estes Park, travel about two miles and then turn right onto Old Fall River Road. Continue three miles, past the Endovalley Picnic Area, and head up the unpaved, one-way road to a trailhead on the left side of the road. A steep trail leads down to a platform with views of Chasm Falls. In the winter, plan on a longer hike as the road may be closed a couple miles back at the West Alluvial Parking area.
Recommended Season(s): May-September
