Our most recent major project was a Field House, equipped with four new indoor basketball courts, retractable baskets, bathrooms, and a conference room. Occupying 22,000 square feet, it is the largest recreational field house of any residential sports camp of our kind.

Our 300 acre facility includes three outpost sites for overnights, many campfire areas, numerous hiking trails, and six exceptional mountain biking trails.


Over the past decade, Greylock has undergone a significant bunk renovation program, adding new windows, floors, roofs, walls, cubbies, and ceilings to every cabin. The cabins also have renovated bathrooms and new beds. Each cabin has exhaust fans that run on a temperature gauge that click on at 68 degrees to blow hot air out and keep the bunk cool.
