Sudden Valley is proud of its community and offers activities for all ages and abilities, including marina, parks, playgrounds, miles of hiking trails, and an 18-hole golf course designed by the renowned course architect, Ted Robinson.

The Community Center is the hub of the Recreation Department and hosts a well equipped fitness center, relaxation areas, children’s playroom, and meeting and event spaces. The Family pool, an outdoor Olympic size swimming pool, is connected to the Community Center.  The Quiet Pool, located behind the Adult Center, is a smaller pool offering a more relaxing swim experience. The Adult Center is home to the South Whatcom Library,  a branch of the Whatcom County Library System.
