The park offers a variety of boating options for visitors. There are two boat ramps available, one on the north side and another on the south end of Lake Quinsigamond. These allow easy access to water-based activities such as sailing, rowing or motorboating. The lake is also home to several regattas throughout the year including college championships and Olympic trials due its 2,000-meter rowing course facility.

You can enjoy freshwater fishing in two main areas: Lake Quinsigamond and Flint Pond. Species include bass, pike, and perch. Boat ramps are available for easy access to the water. Ice fishing is also an option during winter months.
