Best Hikes in Colorado

Colorado hiking is a short season at high altitude, and two of its best areas now need a reservation before you can drive to the trailhead. These are the trails worth the thin air, with the timed-entry rules and the altitude advice that keeps a first day from being a wasted one.

21 trail guides and 8 ready-to-book itineraries

Rocky Mountain National Park and Maroon Bells both gate access by reservation, and both release them on a schedule. The guides above cover how each system works before you book flights around it.

One tap. It goes straight to Yulia and Margarita.

Free permit watch

You can't hike it if you can't get the permit.

The best hikes in America run on lotteries that open once a year and sell out in minutes. Every trail runs on its own calendar. Pick the ones you want and we do the watching.

How it works

  • An email the morning each window opens, never the day after.
  • A 14-day heads-up so you can line up your group and dates.
  • Win odds and a ranked backup plan for every trail you pick.

Didn't win? We keep watching. We check recreation.gov every day for The Enchantments, Half Dome and Angels Landing, and email you the moment a sold-out date frees up. Cancellations are the second chance most people never hear about.
