A Family-friendly Camp

Happy Campers = Happy Families

We know that it takes a village—and a family!—to make summer happen. At St. Mark’s Summer, we recognize the importance of family-friendly options and features that support campers and their families. From easy, online registration and payments to flexible extended day offerings, lunches and snacks provided by us, and nine weeks of summer programming, you can feel confident making plans for your family to join our family this summer. Go ahead, we’ve got your back!

Convenient Location

St. Mark’s Summer is located on the picturesque campus of St. Mark’s School in Southborough, Mass. With convenient access to Route 9, the Mass Pike, and 495, our programs are centrally located for families from many surrounding communities.

Fun for the Whole Family

Our variety of traditional and enrichment camps, along with our SMS summer partner programs, allows families to mix and match to meet the needs of everyone in the family. With one-stop shopping for a range of ages and interests, you can register once and be done!

Lunch & Snack Provided

Take a break from packing lunch this summer! Campers in SMS programs will be provided lunch and a snack each day. Nutritious, kid-friendly lunches are provided by our in-house culinary team, with options for even the pickiest eaters.

If your child has a food allergy or special dietary needs please be in touch with us before the summer. While we make every attempt to be a nut-safe program, SMS cannot guarantee a 100 percent nut-free environment.

Extended Day

Extended care provides flexibility for families with busy schedules. Early A.M. and late P.M. care are available everyday for an additional fee.

A.M.: 7:30 a.m. – 9:00 a.m.
P.M.: 4:00 p.m. – 5:30 p.m.

Campers enrolled in Extended Day programs will engage in a variety of activities with our staff. Late stay campers will also be provided a snack.


As previous classroom teachers, school administrators, coaches, and camp leaders, we know kids. Our leadership team works hard to ensure that all SMS staff have a toolbox of best practices and strategies for supporting campers of all ages. We’ll meet campers where they are developmentally and challenge them appropriately to learn and grow.

Caring Staff

SMS counts on our caring, dedicated, and energetic staff to create the magic of camp. Our summer team includes a mix of St. Mark’s School faculty, coaches, young adults, and local students who are chosen for their skills, passions, depth of experience, strength of character, and embodiment of the SMS spirit. All SMS staff are required to complete CORI and SORI background checks, fingerprinting, and additional licensing requirements based on their role. A full staff orientation is held before our programs begin and all staff are certified in CPR and first aid. Throughout the summer, staff are in continuous partnership with the administrative team to further their own professional development and growth.


SMS is pleased to offer family-friendly discounts to eligible enrollments. Visit our Dates & Rates page for details.

Parents and guardians can download the app from the Apple or Google Play stores for phones or tablets to keep up to date on schedules, events, daily pictures, weekly videos and newsletters – all while you’re on the go! Opt in for text reminders (no more Wacky Wednesday surprise pulling into morning drop-off!) and other updates to help simplify your family’s camp experience. 

A long future at camp!

Visit Us


Please contact us anytime to schedule a tour of camp spaces with one of our Directors.

Though St. Mark’s is a residential high school during the school year, we invite visitors to put on their “camp goggles” as we tour our camp spaces and get a feel for St. Mark’s campus. See where your camper will check-in with their group each morning, eat lunch, play games, and engage in various activities. 

Check back often for updated opportunities to come and check us out!
