Viewline Trail to Skyline Ridge Trail - 8.1 Miles Round-Trip

Sky Mountain Park covers 2500 acres of newly designated open space between the Owl Creek and Brush Creek valleys in Snowmass. 30 miles of existing and in-development trails run through 5 natural vegetation types:

  • Mountain Shrublands (57%)
  • Sagebrush Shrublands (22%)
  • Shale Barrens (9.5%)
  • Riparian Corridors (2.7%)
  • Aspen-Douglas Fir Forests (1.75%)

This diverse composite offers critical winter range and migration habitat for elk and mule deer. Badger, mountain lion, bear and scores of birds have also been documented in the Park.

Several trailheads access Sky Mountain Park with many connection points for creating loops, out-and-backs and reaching Aspen.

The Viewline Trail joins the Skyline Ridge Trail to form an 8.1 mile and-and-back route along the Park’s high central ridge with big views that range from Mount Sopris to Aspen Highlands.

Clean singletrack and mild grades suit mountain bikes, runners and families of all abilities. Dawn and dusk travelers stand a good chance of seeing wildlife in this active area.

The following description accesses the Viewline Trail from Highline Trailhead on Highline Road, just steps up from the roundabout in Snowmass Village. There’s no parking at the trailhead – use free parking at Town Center and walk .1 mile to the trailhead:

The Highline Trail winds .23 miles up to a Map Board and 3-way fork. The Viewline Trail (middle fork) splits up and to the right of the Ditchline Trail and winds tightly through tall crowns of gambel oak and mountain mahogany.

Mount Daly (13,305’) and Capitol Peak (14,130’) stand prominently over Snowmass Village with expanding views across the valley and Elk Mountains. The Viewline Trail rises quickly on a sinuous path that gradually straightens to a crest and the Deadline Trail – Skyline Ridge Trail junction (1.95 miles : 8,595’).

The Skyline Ridge Trail continues straight and dips down across broad sage flats dotted with paintbrush, lupine, phlox and balsamroot. It rolls to the base of a steep knoll (3.0 miles : 8,565’) and wraps NE to a high thin ridge with great views over Owl Creek. Look for elk that gather in these pastoral meadows from April – late June.

It winds steeply down then undulates moderately along the ridge to the Airline – Cozyline Trail split (3.95 miles : 8,475’). The Skyline Ridge Trail continues to its terminus at Cozy Point on Radar Road above the Aspen Airport (4.05 miles : 8,514’).

Those seeking longer and more varied routes on the return can split off on the Cozyline-Cozy Point Loop or Daedline Trail, both of which will return you to the Viewline and Skyline Ridge Trails.

Worth Noting

  • Shrublands of Sky Mountain Park require periodic, low intensity fires to maintain natural specie density and balance. Aging gambel oaks can form thick stands that crowd out other shrubs and produce fewer acorns and high fuel loads. Sky Mountain Park simulates natural fires through periodic cutting to maintain a healthy ecosystem.

Camping and Backpacking Information

  • Camping is not permitted in Sky Mountain Park. Day use only.
