Round Valley Recreation Area offers public boat access to Round Valley Reservoir via two boat ramps located north of the day-use area, regulated by the NJ Division of Fish and Wildlife and requiring a valid NJ fishing license or ramp permit.

Motorboats are limited to 10 horsepower, and sailboats, canoes, and kayaks are also permitted; all boaters must wear Coast Guard-approved personal flotation devices.

The area features a day-use beach complex with amenities, picnic areas, and parking, with additional wilderness camping accessible by boat or hiking for extended visits.
