Join the TNI Trail Challenge Club to get exclusive access to trail-themed stickers and the chance to hike with a seasoned guide on all of our trails. 

How do I Join?

• Join the club for $25. Then head out and hike.

Can I hike the trails on my own?

• Yes! All we ask is that you send us a screenshot of the trail you hiked in your favorite hiking app or a picture of yourself out on the trail. Then we will make sure to have your sticker for you the next time you come out. 

I am not comfortable hiking the trails on my own.

• That is ok! Throughout the year, TNI staff will lead a hike of our different challenge trails and you can join up with that group. Only members of the trail challenge club will be invited to join these hikes.

When can I pick up my stickers?

• You can pick them up as you go by coming out and talking to a staff member or letting us know when you want to pick it up. We will leave your sticker in an envelope in a bin at the lodge for you to pick up at your convenience.

Why do I want these stickers?

• The stickers you will receive are waterproof and will be a perfect decoration for a water bottle or your computer or any other thing you like to put stickers on. There are 11 stickers you can collect over the course of 2026.
