Unless otherwise posted, all recreation programs through Mount Vernon Parks & Enrichment Services do require preregistration. Most programs do require a minimum number of participants. If a program does not receive the required minimum number of participants, the program may be rescheduled or canceled. In order to register for a program, a program registration form must be completed and signed either by a legal guardian or program participant if over 18 years of age. The registration fee, if applicable, must be paid in full at time of registration. You can register online at https://apm.activecommunities.com/mvparks/ , or in our office at Hillcrest Park (1717 South 13th Street) or over the phone at (360) 336-6215, with a VISA, American Express, Discover, or MasterCard.
