The Gymnasium, also called the "Small Gym," is home for the SNHU Intramural Program. The rubberized floor, updated in 2018, satisfies the needs of many different recreational sports, such as volleyball, dodgeball, basketball, floor hockey, indoor soccer, and more. The Small Gym also features a full-sized stage that is often host to other school events like dinners, concerts and plays. The small gym can accommodate up to 300 people comfortably in the bleachers.
The Small Gym is also used for practices for several varsity teams during the winter months, including baseball, softball, men's and women's lacrosse and men's and women's soccer.
