Camper reading in tent

Since its founding in 1921, Camp Treetops has been a place where children from the U.S. and around the world come together for a summer of growth and friendship. Each year, campers join us from a wide range of countries – one in six campers is international. With plenty of time to explore lakes and mountains, and space to be themselves, they become strong, independent, and part of a community.

Being immersed in camp culture and activities – and interacting with native English speakers – campers make significant strides in language acquisition. Campers with limited English make quick progress in listening, speaking, and comprehension in our supportive community. English language classes – individual and small group – meet three times a week.

“He couldn’t stop telling me about the wonderful time he had during the camp, and how nice the teachers were to him. I am so happy to see that not only did his English improve a lot, but he is also more mature than before. I think this experience was incredible to him. Thank you all for making this summer so wonderful and meaningful for him.” (CTT Parent)
