The East of Aspen Trail is a very popular walking and biking trail that follows the Roaring Fork River from town out to the Difficult Campground entrance for just over 3 miles. Along the way, the trail passes some very nice conservation areas and offers great views of the hills on either side of the river.
The first portion closest to town is paved, but most of the trail is a nicely-maintained, wide dirt track. One section near the campground is a wooden boardwalk over the river wetlands. The North Star Preserve is a large area of wetlands and meadows that adjoins the East of Aspen Trail for much of its route. This preserve houses a rare and unique great blue heron colony and at least six species of birds that nest on the ground. There are several side trails into this preserve for viewing wildlife. While dogs are allowed on the main trail, they are not allowed into the preserve. One area at the east edge of the North Star Preserve is used as a landing area for paragliders that take off from Bell Mountain and soar high above the river and valley, so morning travelers on this trail should keep an eye on the sky to spot their colorful chutes.
