Lots of water traffic year round in this area but no need to get your feet wet while searching for this cache.
The intercoastal waterway is a 3000 mile inland waterway along the Atlantic and Gulf Coasts. Some sections of the waterway consist of natural inlets, saltwater rivers, bays, and sounds, while others are artificial canals. It provides a navigable route along its length without many of the hazards of travel on the open sea. The nearby lock connects the southern branch of the Elizabeth River (which you see from the cache site) with the Abemarle and Chesapeake Canal. The Albemarle and Chesapeake Canal was built by a corporation in 1856-1860 to afford inland navigation between the Cheapeake Bay and the Abemarle Sound. It is really two canals, thirty miles (50 km) apart, one eight and one-half miles long, which is to the south of this park and the other five and one-half miles long, connecting the Currituck Sound with the North River in North Carolina.
This is a fairly popular fishing spot so use caution or educate the fishermen if they are present when you seek this cache.
