The Junior Program has nearly unlimited access to St. Mark’s extraordinary facilities. In addition to superb classroom spaces, there are art studios, a theatre, an excellent health center, and an award-winning science center. The school’s sports facilities rival those at many colleges and include a multi-million dollar sports complex, with eight playing fields, eight tennis courts, and a pool.

Southborough is 26 miles west of Boston, giving students a unique opportunity to enjoy one of the nation’s great historical, cultural, and educational centers. In addition to its proximity to Boston, St. Mark’s School is only 15 miles from Wellesley College, making it easy for Junior Program students to visit brothers and sisters at the Exploration Intermediate Program.


Campus NotesThe Junior Program has access to: 8 playing fields; 8 outdoor tennis courts; 2 indoor basketball courts; a large swimming pool (no deeper than 6 feet and only 3.5 feet through most of its length, making it perfect for instructional swimming and water games); indoor performance spaces for student talent shows and productions; more than 600 lion images or sculptures hidden in and around the architecture; on-campus pond for canoeing, kayaking, and course study; a 26-mile proximity to Boston for weekend trips to popular sites such as the Museum of Science and the Boston Duck Tours.

In order to help families make travel arrangements for their children, Exploration has partnered with Colpitts World Travel. By booking through Colpitts, you can quickly determine how many other Exploration students are already on a flight and whether the flight arrives during our regular airport pick-up hours. If it does not, Colpitts can book travel between the airport and campus through another Exploration transportation partner, BostonCoach. Colpitts negotiates discounts with the major airlines and therefore, their pricing is very competitive.

We did quite a bit of research to make sure both companies could service our families worldwide, and because we are dealing with students under the age of 18, it was imperative that we find partners who would meet our high standards. Colpitts, a leader in the travel industry, will be able to assist families with unaccompanied minor paperwork as well.

Families are not required to use the services of either company, but if you would like to do so, you can book through the Exploration page of the Colpitts website. Alternatively, you can call Colpitts at 781.326.7800 and mention that you are calling for an Exploration Summer Program student. Families interested in livery service can reach BostonCoach directly at 800.672.7676. Please use Exploration account number #91030 with BostonCoach to receive a discounted rate.
