Swim and Tennis Association

The Belmont Day Swim & Tennis Association (STA) provides families and individuals with access to the swimming pool, tennis courts, play structure, and locker rooms during designated hours in the late afternoon and evening and on weekends during the summer. Order a pizza to be delivered to the pool, bring a picnic dinner, or just bring your towel for a quick dip after work or camp—STA offers a relaxing summer spot.

Membership is open to school and summer camp families, faculty and staff, alumni, neighbors, and to the public. For camp families, Swim and Tennis Association membership may be added during camp enrollment. Contact summer@belmontday.org for more information.
