A friend who lives near Aspen suggested Ashcroft Ghost Town as a first hike of vacation–one for altitude acclimation. Just 12 miles south of Aspen, this tucked-away historic spot was the perfect easy adventure—and after an overnight snowfall, it turned into something pretty magical. What started as a simple tip became one of those quietly unforgettable days: bluebird skies, untouched trails, and a ghost town softened by fresh powder. We had the place almost entirely to ourselves, sharing the landscape only with curious marmots, a few passing geese, grazing mule deer, and the constant soundtrack of twittering birds echoing through the valley.
A Brief History of Ashcroft
Founded in the 1880s during Colorado’s silver and gold boom, Ashcroft quickly grew into a bustling mining hub. At its peak, it was home to saloons, hotels, and a growing population chasing fortune in the surrounding mountains.
But like many mining towns across the Rockies, prosperity didn’t last. As the ore veins diminished, so did the town’s population. Within a few decades, Ashcroft was largely abandoned—left behind as a quiet reminder of Colorado’s boom-and-bust past.
Long before miners arrived, this land was home to the Ute people, who were eventually displaced as settlers moved into the region.
Today, several original buildings still stand, carefully preserved with interpretive signage that brings the town’s story to life without overwhelming the experience.
Trailhead & Parking
Ashcroft is located on Castle Creek Road. From the west Aspen roundabout (route 82), head south on Castle Creek for approximately 12 miles. The parking lot is located on the east side of the road, with plenty of spots for visitors.
Parking is free, however there is a $5 per person fee, typically collected at the Welcome Center. In winter and shoulder seasons, use the honor box system located on a nearby signpost. The fees support the Aspen Historical Society.
Vault bathrooms are located at the end of the parking area.
Just across from the town is the Catto Center at Toklat, run by the Aspen Center for Environmental Studies. If it’s open, typically Thursday–Sunday, 10 am–4 pm, it’s a great quick stop for a deeper look at the ecology and wildlife of the Castle Creek Valley. Check current hours on AspenNature.org.

The Town & the Hike
The main route through Ashcroft follows the River Run Trail—an easy, well-marked path that winds right through the historic townsite before continuing alongside Castle Creek. Before setting out, it’s worth noting that Ashcroft sits just under 10,000 feet. Even though this is a mellow, mostly flat walk, the altitude can still catch up to you. Take your time, sip water often, and ease into the pace—especially if you’re coming from lower elevations.
Interpretive signs border the path, providing you with as much information as you choose to read about the historical town. In the quiet, reading the historical placards, I found myself imagining life in the 1800’s, with hopes of fame and fortune. I even climbed to the second floor of the two-story building, peering out the windows to the mountains above and my husband below. Just outside the building, a path leads to the creek and connects to an unnamed path that circles back to the main road.
After passing the buildings, the trail opens up and the scenery shifts. The creek winds alongside the trail, weaving through tall evergreens. As the trail nears Castle Creek Road, Castle Peak, one of Colorado’s iconic 14ers, rises in the distance. The view is stunning–light sparkles off the rushing creek and seems to point to the majestic mountains.
Cross the road to the Pine Creek Cookhouse. From this area, the views really open up. To extend the hike to higher elevation and mountain lake views, take the Cathedral Lake Trail from this juncture.
The path is gentle and leads back to the parking lot.
Optional Hikes
Two popular options include the Cathedral Lake Trail and the American Lake Trail. Both climb steadily into alpine terrain, trading the gentle valley floor for steeper ascents, dense forests, and eventually wide-open views. These routes are especially stunning later in summer and early fall—but in spring or snowy conditions, they become a very different kind of adventure.
Snow Safety
Snow lingers well into late spring due to the elevation, and trail conditions can shift quickly. If you’re considering extending your hike to higher elevations:
- Plan for deep snow: Snowshoes or traction devices may be necessary, even when the lower trail appears clear.
- Be mindful of remoteness: These trails see far less traffic than Ashcroft itself, so be prepared for self-sufficiency.
- Watch for unstable snow: Spring snow can be deceptively firm on top but hollow or weak underneath. Areas that look packed down may collapse underfoot, especially in the afternoon as temperatures rise.
- Start early and assess conditions: Morning travel is typically more stable, while warming temps can quickly change the terrain.
The Experience
The Ashcroft-River Run Loop isn’t a challenging hike—but that’s exactly its appeal. It’s accessible, scenic, and layered with history, making it an ideal outing for a slow morning or a peaceful afternoon near Aspen.
And if you time it right—just after a spring snowfall—you might find yourself in a quiet winter wonderland, walking through both history and fresh powder at the same time.
