The shelter can be rented from 8 a.m. to dark (all day). Customers renting all day must leave park at sunset. This shelter is rented with a tent cover May through October each year by reservation only. Other months of year, it's an open-air, first-come, first-served picnic area with tables and grills.

Cancellation policy: No refund within 14 days before reserved date. Before then, there's a cancellation fee of $10.

Amenities: Visitors should contact the park to pre-pay parking fees for their group as a whole. The use of a caterer requires a special use permit, which can take up to 30 days to receive. The park is open daily 8 a.m. to sunset; there's no swimming at this park.

Shelter 1 Tent Shelter (small). The shelter is a 40 x 20 foot framed tent; there are no holes in the center, and sides are open. The floor is gravel. The tent's roof is vinyl. There are 10 picnic tables and two pedestal charcoal grills. It seats 50 people at one time; a group of more than 50 but fewer than 100 people can use the site (although shelter rental does not guarantee sole usage of the area open to the general public). Guests will need to bring lawn chairs. Erecting additional tents is not permitted. Additional tables and grills, likewise, is discouraged. Parking space is adequate, but it may be necessary on busy weekends to offload supplies and park elsewhere in the park, still within walking distance. The shelter is near a general picnicking area that the general public uses. Restrooms are about 60 feet away. There are no electric outlets or water hydrants.

Hiking, biking and self-guided trails. More than three miles of hiking trails wind through the park providing a glimpse of nature by the bay. Elevated walkways allow visitors to explore some of the marsh areas in the park. Ten bicycles are available for rent by the hour.

The park is in the southwest corner of Fairfax County, approximately 20 miles from Washington, D.C. Access to the park is via U.S. 1, then five miles east on Route 242 (Gunston Road) to the park entrance.
