The Germantown Indoor Swim Center (GISC) is one of the county's major aquatic facilities, and the Spring 2026 Guide is packed with over 100 swim lesson sessions, water fitness classes, diving programs, and more. The Loop Team pulled every GISC program from the guide so Gaithersburg-area families can find exactly what they need.
Located at 18000 Central Park Circle in Boyds (serving the greater Germantown/Gaithersburg community), GISC offers a full progression of swim instruction from Water Babies at 6 months through competitive high school diving. This spring's lineup also features water fitness for adults, a developmental swim team, lifeguard certification courses, and family swim parties.
