Welcome to the Colorado Six-Pack of Peaks Challenge!

Get ready to flex your adventure muscles! You are now part of the Six-Pack of Peaks community.

Your welcome packet will be mailed to you in the next five to seven days and contains your sticker packet and other goodies.

Here's how to get started

Start planning your hikes

We have detailed trail guides to all the peaks in the challenge, but remember, these are just suggested routes. You can hike from any trailhead you prefer to make it challenging for you. You can hike them in the suggested order, or in any order you prefer. Start putting dates on the calendar and planning those hikes.


Check out what your fellow challengers are up to, and gain some valuable trail beta, with the hike logs.
