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.

"My favorite part of Sierra Adventure was the challenge hike — it was rewarding and had the best views."

"Thank you for another great trip this summer. Nolan had a great time; he enjoyed the leaders, the other campers, and all the activities. As a parent, I feel like he grew socially while he was away. Thank you for providing him a safe and fun environment to have a blast outside and grow as a person! "
