Introducing the Trans-Sierra Xtreme Challenge.

Serious wilderness.

You'll spend one week, unplugged, traversing some of the most remote, least traveled regions of the Sierra with a small group and two incredibly experienced guides.

Open to everyone.

Our treks are open to motivated individuals of all ages. So grab your kid, grab your parent, grab your best friend for life, and create memories that will last a lifetime.

Packed with inspiration.

Get knee-deep in high Sierra steams, scale snow covered passes, drop into remote canyons, summit jagged granite peaks. And we're still keeping the best part a secret.


Bring your Attitude.
