What to expect backpacking with TSX Challenge.

Discover awe-inspiring terrain and unplug off the grid while accomplishing something big. Our small group guided backpacking treks are team-oriented, easy to join, and open to all ages, backgrounds, and experience levels.

Open to all

Fit and motivated people of all ages, backgrounds and experience levels are welcome.

Off the grid

No email, no social media, no news cycle. Unplug in serious wilderness accessing destinations many only dream of.

A challenge

Our treks may stretch you just outside your comfort zone, allowing you to reconnect with the spirit you’re made of.

Team effort

From start to finish, each trek is a team effort. Reach goals that would be more difficult to accomplish on your own.

Easy to join

Show up with your personal items ready to hike. We take care of gear, food, permits, transportation and logistics and more.

What we believe.

No matter your age, background, shape or size, we believe you have what it takes to accomplish incredible things. Whether it’s summiting Mt. Whitney (14,505′), or sleeping at the bottom of the Grand Canyon, backpacking our nation’s remote backcountry has the ability to change people’s lives. Our trails have had an incredibly positive impact on our family, friends and community. We hope it can have an equally positive impact on you, renewing conviction you can accomplish anything you put your mind to.
