Don't expect too much, so you won't be disappointed. If your idea of a "ghost town" is falling down buildings in a deserted, haunting atmosphere, you will let down. This is a federal historic site for a town that, at its mining height, had more than 2,000 residents. It rivaled Aspen, before the thin silver veins ran out. On a high plateau, ringed by beautiful moutains, it's a stunning setting.
Ashcroft is an easy, scenic 15-20 minute drive from Aspen (clearly marked road from the last traffic circle before you come into Aspen - at the chapel circle). The 'town' consists of 8-9 preserved or reconstructed buildings with a very nice gravel walkway running down Main Street. There are a few saloons, a house, a bank and a hotel. You certainly get an idea of what the small buildings looked like - just multiply it many, many times to get an idea of the original town. Very informative signs along the way explain to you of a variety of aspects of living way, way out of the way in a town getting 12 feet of snow every year. The setting and the peacefulness of the surroundings are wonderful, especially compared to the bustle of Aspen. It's a very nice break (bring a lunch!).
The gorgeous river runs nearby, with paths going down to it.
It is a special place. If you really are into ghost towns, go into and then out of Aspen to the east and drive (very carefully) up toward Independence Pass. There you will see the more 'fallen apart' ghost town of Independence. Then you can imagine winters above 10,000 feet. Ashcroft was Boca Raton compared to Independence!
