A public gathering permit is required for groups of people who wish to hold assemblies, meetings, gatherings, demonstrations, parades, or other public expressions of views on park property.
Gatherings of 25 or less people may not require a permit. The easiest way to determine whether your small group needs a permit is to fill out the application form and contact the park.
There may be a required application processing fee.. Applications must be received a minimum of two business days before the public gathering begins, however there may be requirements that the applicant may need more time to fulfill, such as scheduled meetings with the park, adjustments to the planned activity, bond and/or insurance requirements..
Contact the park's permit office at 703-289-2513 if you have any questions.
