Historians believe that Sanibel and Captiva were formed as one island about six thousand years ago, as sediment that rose from the sea after being shaped by centuries of storm activity.
Dating as far back as 2,500 years, the native Calusa Indians were the first-known residents of the island.
A new, higher bridge, permitting passage without a bascule bridge (drawbridge) of tall boats and sailboats, was completed in late 2007.
The Calusa proved to be skilled builders and craftsmen, perching their huts high atop shell mounds to provide protection from storm tides.
Some of their shell mounds, which were also used for ceremonial, ritual and burial sites, remain intact today.
With cool breezes, gorgeous sunsets and white sandy beaches, the coastline of a tropical paradise is also the ideal place to hold a family reunion trip.
