The Reservation has two boat ramps. They are right next to each other and provide access to Black Rock Creek. The end of the creek, where it empties into the Merrimack River, is a stone’s throw away. The mouth of the Merrimack, where it feeds into the Atlantic Ocean and divides Salisbury Beach from Plum Island, is just a few minutes away by boat. Both boat ramps are accessed from a small parking lot found southwest of the campground.
