We Welcome Your Application to Join Us!

We build each of our groups with care, keeping the groups small (no more than twelve students), and paying close attention to age, grade, gender, and the mix of hometowns and schools. Our goal is to put together great groups — groups where nice kids thrive in a supportive, wholesome, and caring environment. Please note: availability as shown is based on students traveling without a friend; if your child is interested in traveling with a friend, please call our office for availability.

Sierra Expedition

Two weeks in California's high country, plus a climb of Mount Shasta!

Explore the Sierras & Climb Mount Shasta!

California is more than its coast and cities. California is mountains and rivers, granite domes and snowcapped volcanoes. This is the California we’ll see and experience on Sierra Expedition.

Every Overland trip is a carefully crafted series of challenges with clearly defined goals. Sierra Expedition is no exception. In the Sierras, our two weeks of hiking offers brilliant sunshine and big views. On the American River, the rafting is exciting, and it’s ideal for first-timers and groups like ours (and we’re cared for by terrific guides). And, then there’s Shasta: 14,000 feet of volcanic beauty just waiting to be explored by us and our talented mountain guides!

As with every Overland trip, we’ll see and experience these places with a small, fun group and great Overland leaders. This is what makes all the difference. An Overland group — always limited to twelve kids, always carefully put together — is a spirited, enthusiastic, positive, and wholesome place. And Overland’s leaders? They’re the best — caring, supportive, and fun-loving.

Hiking in the Sierras and climbing Shasta with Overland will show you the world in a new light. That’s what’s so special about an Overland trip: the challenge, the group, new friends, and lifelong memories that we can share together. What could be more wonderful than that?
