I have traveled to about 50 countries and have done things like trekking in Nepal, climbing Kilimanjaro, and hiking in the Swiss Alps, and this trip ranks up there along with those as great experiences.

Truly an amazing experience that I’ll remember for life. This was my first backpacking trip, and I’ve never carried a 30+lbs pack ever before. Looking back, I cannot believe I completed this challenge and can’t help but feeling so proud of myself.

I hiked the Grand Canyon with a group of women from who were all participating in #52hikechallenge. Several had never camped or backpacked before. To a person, we all had an awesome time. Great views, challenging terrain and incredible guides.

If you are looking to explore the Sierra in a way that others rarely do, then sign up for this trip. It will probably be one of the hardest and most rewarding things you will do. The views are spectacular, the food is delicious and TSX has fantastic guides and leaders.

This hike fulfilled an ambition to climb Whitney that had been burning away at me for six years. TSX led us expertly, always managing expectations. We bonded almost immediately as a team. All of us were able to reach the top of Whitney, despite many of us having doubts.

At some point during our adventure, the 9 of us on the trip became a team, helping each other along the way. Truly great friendships were established, and I look forward to more adventures with the TSX team (family)!  It was amazing, even better than anticipated.

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.

Meet Our Team


A warm embrace from the “Mighty Blue” podcast

Whitney, Appalachian Trail thru hiker and Hiking Radio Network podcaster “Mighty Blue” Steve Adams connected with TSX co-founder Chris Casado at the suggestion of a listener. Nearly one year later, his third attempt was a success. What was the missing ingredient? Follow his journey to Mt. Whitney on a three part podcast.
