Sunnyside Trail

Enjoy sweeping vistas of the Elk Mountain Range and Aspen’s bustling ski resorts along the Sunnyside Trail. Like the name suggests, this trek is exposed to the sun, which makes for extremely warm conditions in the summer months. We suggest heading out in the early morning to beat the heat and the crowds! A great way to acclimatize to the area’s altitude, this trek does ascend in elevation. Be sure you pack plenty of water — way more than you anticipate needing. Trust us, the vertiginous terrain and exposed path will tire you!

Departing from the Rio Grande Trailhead, the Sunnyside Hike will briefly track the Rio Grande Trail before merging onto the Sunnyside Trail at the first intersection. Hikers will have to cross over McLain Flats Road before beginning the climb through the meadowlands. Ascend the vertigo-inducing terrain through several switchbacks up to the radio tower. From this point the terrain will be more level and shaded as it guides adventurers briefly along the edge of the woodlands.

From the southern slope of Red Mountain you will be rewarded with sweeping views of the mountainous landscape that stretches for as far as the eye can see. Soon you will meet the trail’s end. If you want some shade, consider trekking the Shadyside Trail before reconnecting with the Sunnyside Trail and heading back to the trailhead. If not, retrace your footing along the same path back to the parking lot.
