  1. Offering great views of downtown Aspen and a lovely jaunt through scrub oak and wildflower fields, Ajax Trail is among Aspen's most accessible and shortest trail runs.

  2. The Ute Trail is Aspen's most challenging trail run. This steep, heavily used trail features sharp switchbacks, large rooks and rocks in some places, located on the southeast side of Aspen, ascends 700 feet in less than a mile. Many runners use the scenic rock outcropping at their turnaround, located at the .9-mile mark, and others continue for another 2,300 feet to the summit of Aspen Mountain, also known as Ajax Mountain. Many Aspen locals run up the Ute daily to stay in top physical condition.

  5. This 8.4-mile out and back route crosses multiple creeks including Lincoln Creek, New York Creek and Brooklyn Creek Gulch and can be tricky during high spring runoffs, but expansive high-alpine meadows and stunning views of the Collegiate Peaks make it well worth the effort. Experienced high-country trail runners will appreciate the 2,160-foot elevation gain, while the less experienced may find the trail a bit strenuous.

  7. Weller Lake is a forested mountain lake below the treeline that offers a great short run through spruce and aspen trees. It's nice to take a couple hours so you have time at the lake for lunch or a snack, and maybe a dip. The best time to go to Weller Lake, and most everything else in the high mountains around Aspen, is morning. Thunderstorms are common in the afternoon, especially in July and August. High snow years will prevent access to the lake until early June.

  8. East Maroon Creek Trail is a nice option for a casual 10-mile out-and-back trail run or the gently sloping, eastern edges of the Maroon Creek valley. Offering views of the rugged 14,000-foot Pyramid Peak and 1,200 feet of elevation gain from trailhead (8,680') to turnaround (9,880'), the route climbs pleasantly for most experienced hikers. The trail continues to East Maroon Pass and then to Copper Basin and eventually Crested Butte, which many overnight hikers/campers do during the summer months.

  10. Offering great views of downtown Aspen and a lovely jaunt through a pine forest and wildflower fields, the Little Cloud Trail is among Aspen's most accessible and shortest trail runs. Little Cloud begins from Midland Trail, a former railroad track that is now used for commuter bikers and walkers. Little Cloud is situated at the base of Shadow Mountain, the rocky, sharp ridgeline that juts out from Aspen Mountain on the western side of town.
