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.

Campbell Day

Hometown: Marin County, California
College: Williams College

At Williams College, I am a member of the women’s soccer team that won back-to-back NCAA national championships in 2017 and 2018.

Originally from Marin County, California, I am a senior at Williams. I am a psychology major with a concentration in neuroscience and am a second grade buddy at a local elementary school. I love spending time with my family and friends: we enjoy adventures — whether hiking through redwood forests or body surfing at the beach.

In 2018, I led Berkshire Adventure, New England Adventure, Maine Adventure, and in 2019, I led Rocky Mountain Explorer. This summer, one of our day hikes in Rocky Mountain National Park was a lake hopping day; we went to Dream Lake, Lake Haiyaha, and Mills Lake. Lake Haiyaha was absolutely beautiful; it was turquoise with a backdrop of snowcapped mountains. We saw the snowmelt flowing into Lake Haiyaha — we knew it was going to be cold; however, nearly everyone in our group braved the glacial temperatures of the lake. They jumped in, yelling and hollering about the freezing cold with smiles on their faces, as the lake literally and figuratively took their breath away.
