Welcome to TSX Challenge.

We take motivated people, band them together, and enable the to access some of the most remote, least traveled regions of the Sierra, Grand Canyon and beyond on our inspirational guided backpacking treks. Each challenge traverses awe-inspiring terrain, completely unplugged, with a small group and incredibly passionate guides. While our treks can be intense, no prior backpacking experience is required. Just bring your mental toughness, positive attitude, and be ready for an experience that can inspire for a lifetime.

Watch video to learn about our experiences.
