About our camp
Camp Mataponi is a traditional girls overnight summer camp located on Sebago Lake in Naples, Maine. It was founded in 1910 and with over 100 years of history and rich traditions, today Mataponi is still enriching the lives of its campers. The camp has been owned and operated by Marcy & Dan Isdaner since 1994, and with over 20 years of “hands-on” experience, they’ve enjoyed helping thousands of girls make memories of a lifetime. Being the best you can be, that’s something Mataponi believe in. Campers attend one seven-week session, with approximately 320 girls attending every summer. The girls enjoy a healthy balance of creative fun, competition and an appreciation of others in a safe and empowering environment.
Our programs
We offer a healthy balance of land sports, watersports, fine arts, crafts, ropes challenges, outdoor adventure and much more. There is also over 5000 feet of beachfront, boating and swimming in Sebago Lake to enjoy activities such as tubing, wakeboarding and slaloming. Our motto is “You don’t have to be the best, just try your best".

Program-specific tuition options
This camp may offer session-specific tuition structures, including variations by length of stay, enrollment timing, or payment schedule. Families should confirm details directly with the provider.
Per-night (overnight) and per-day (day) figures are calculated from each session's standard tuition and shown as a planning reference only. We show the lowest per-night or per-day rate across this camp's sessions, so the total for a given session, and your actual tuition, may be higher depending on length of stay, age group, or enrollment timing.
This estimate helps families understand the overall scale of commitment across stay options. Final tuition, inclusions, discounts, and payment structures vary by session and are confirmed directly with the camp.
