This community was once called Witt. It, along with its neighbors Atlantic and Cedar Island were established in or before the 16th century. It is difficult to determine the exact dates due to the fact the few of the people back then could write and if they could record during this time would have been easily lost as a result of lack importance felt at the time and that grave markers were in the main made of wood due to the lack of availability of stone in this area.

Sea Level has a great deal to offer its visitors. One can go camping with an RV or tent at its campground that is equipped with a boat ramp and a swimming pool.

Nelson Bay affords a gate way to Core Sound and the Core Banks plus a great fishing, sailing, kayaking, PWC and swimming plus the most fantastic sunsets you've ever seen.

There is also a full service banking facility here, an extended care facility; doctor's office; pharmacy and a premier retirement center for both worn out and tired seamen called Snug Harbor at Nelson Bay. Snug Harbor until recentally was the nation's oldest charitable institution and houses and displays wonderful if not the best maritime artifacts and art in the country. Tours are available by appointment.
