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 Explorer

Mountains, lakes, and sunshine in California's high country.

The Sierras are bold and wild, impressive and inspiring.

Hike Yosemite National Park. Pass through fragrant pines and swim in sun-soaked lakes in Stanislaus National Forest. Raft the rollicking American River.

Sierra Explorer offers thoughtfully designed activities: hiking, backpacking, rafting. All perfectly sized and paced for our groups.

The goal is friendship: Time together in a new and exciting place, shared tasks and challenges, teamwork and group living. Wonderful friendships grow in a positive, supportive, and wholesome atmosphere overseen and nurtured by Overland’s leaders.

The focus is fun: Many — maybe even most — of the kids who come are first-timers on a trip like this, so we keep the focus on fun, the tone upbeat.

The result? Maybe just the best summer ever. At trip end, we’ll revel in the places we’ve been and the feats we’ve accomplished. Even more so, we’ll enjoy the bonds we’ve created as a group — the type of bonds that come from spending two weeks in a beautiful place, pursuing fun activities, and relying on each other for support.
