Our History
Sierra Summit Expeditions began over 14 years ago when James and Brett, two avid outdoor enthusiasts, met on a mutual friend's hiking trip in the Crystal Basin Recreation Area. What started as simple hiking and fishing excursions soon evolved into backpacking adventures, including snow camping and snow backpacking trips. Their love for the outdoors and passion for adventure naturally led them to share their experiences with others. Early on, they began inviting newcomers to join their expeditions, taking pride and finding fulfillment in teaching those new to backpacking the skills necessary for successful and enjoyable trips.
James and Brett's dedication to sharing their knowledge and passion for the wilderness has only grown stronger over the years. They have refined their approach to ensure that each trip is not only an adventure but also an educational experience. Their goal is to make backpacking accessible and enjoyable for everyone, especially those new to the activity.

We aim to provide a welcoming and educational environment for individuals new to backpacking, ensuring they have the skills, confidence, and gear needed for a safe and enjoyable experience.
