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 Adventure

For two unforgettable weeks full of summer adventure, hike though wildflower-filled valleys, along pristine mountain lakes, and below granite peaks in California’s Sierra high country.

Explore California’s Sierra high country.

Hike to stunning views in Yosemite National Park. Kayak the crystal-clear waters of Lake Tahoe. Raft the thrilling American River. The best of California in two weeks.

For many students, this trip will be their first time away from home. Leaving home can be hard, but we keep our days packed full of fun. Most of the day we’ll spend hiking, kayaking, or rafting. The day hikes are exhilarating — hiking to beautiful viewpoints, or rocky, arid terrain that gives way to clear lakes (perfect for swimming!) — and we make sure to stop along the way for snacks and games. The kayaking brings you along jagged shorelines and around sunny beaches. And the rafting? Well, it’s a full day of splashing and fun, perfect for beginners!

The downtime is fun, too. Guided by kind, charismatic leaders, afternoons at our campsites — beautiful spots among fragrant stands of pines, or beside shimmering blue lakes — are spent learning about flora and fauna, making friendship bracelets, or playing frisbee. At night, we share in the responsibility of making delicious, healthy meals, and take time to gaze at the stars. No matter what we’re doing, we do it together. On Sierra Adventure, making friends is easy!

In San Francisco at trip end, we’ll celebrate all of our accomplishments, all of the fun we’ve had, and all of the friendships we’ve made in California’s rugged and beautiful mountains. Sierra Adventure offers the chance to see the West with an enthusiastic, adventurous group guided by caring, capable Overland leaders. All of the trip’s activities have been carefully chosen to suit 6th and 7th graders — it’s a great way to experience Overland.

Good Things to Know. The group is always small — no more than 12 students — and we always have carefully chosen and thoroughly prepared leaders. The itinerary is crafted to provide just the right mix of activities — the goal is to have every student love their Overland experience. The camping is in private campgrounds and state and national parks, all of which offer full facilities, including hot showers. Meals are wholesome, nutritious, and varied… and they’re fun group projects with input from everyone and lots of guidance from the leaders. Getting to and from the trip is a breeze: there are excellent flight options into San Francisco and we provide supervision on arrival and departure so that travel days go smoothly.
