Beautiful in the fall
The scenery in September/October is beyond words. Not only do the changing colors of the Aspen make this the perfect time of year, there are also fewer tourist and access is free. This is NOT an easy hike. At an altitude 10200 the oxygen is very thin, even for those of us who live and work in Aspen. This is not a smooth walking trail! The terrain is very rocky, and it is easy to twist an ankle or trip. There are no conveniences along the way, so bring and drink plenty of water, take advantage of the restrooms before starting up, and an energy snack isn't a bad idea. If anyone in your hiking group becomes lightheaded, develops a headache, nausea or cramps, you may want to consider ending the hike. These are signs of altitude sickness and can become severe.
