The North Carolina Aquarium is a great activity for the whole family.  The inside of the Aquarium is beautiful with many different types of fish and wildlife from the outer banks.  There is even a touch tank to see horseshoe crabs up close.  The Aquarium also has some more in depth exhibits for the adults.  Outside of the aquarium there is a path to walk along the sound.  On that path is a "dump" of sand that has been dredged up.  There you can dig for sharks teeth, whale bones and other fossils.  You will ALWAYS find something in it.  So bring a spoon and a plastic bag because you don't want to miss this activity.  The aquarium is a great place to go on a rainy day or on a too hot day. 

Manteo is a nice town with restaurants and shops.
