 Incorrectly claimed by locals as the world's second longest natural sand bar, the Eel River Bar, is a barrier beach located at the mouth of the Eel River immediately west of the village of Charlo, New Brunswick.This sand bar is unique not only because it has fresh water on one side and salt water on the next, but because it is home to the endangered piping plover.Tourism in the region has been driven in the summer months by users of the bay's beaches.
