If your trip to Manteo is all sorted out but your travel itinerary is looking a little empty, let us give you a helping hand.Close to the city center, North Carolina Aquarium at Roanoke Island is one attraction you might like to consider putting on your must-see list. If you still have some room on that itinerary, Pirate's Cove Marina and Fort Raleigh National Historic Site will keep you entertained too.
