Cockspur Island lighthouse just to the east of Savannah is visible from the causeway leading to Tybee Island. The tiny oyster shell island on which it sits is only two hundred feet long and fifty feet wide depending on the tide. Flocks of birds use it as a feeding ground when it is exposed by the low tide. To explore the forty-six foot tall tower you either have to pay close attention to the tide tables or wade to or from the island in hip deep in water and surf, which isn't recommended. At high tide Cockspur Island lighthouse's foundation is lapped by the waves (below).

The Cockspur Island lighthouse also known as the North Light, was built in 1857 and replacing an earlier lighthouse built in 1848. Cockspur marked the South channel of the Savannah River and remained in service until 1949 except during the Civil War when it was darkened. It is seldom visited since access to it is inconvenient. Undaunted, Cockspur Island lighthouse remains standing at its post even though there has been no light in its lantern room since it was decommissioned. Another lighthouse built nearby and of the same design as Cockspur Island has not survived the storms and ravages of time.
