Without question, the greatest attraction of Sanibel is its beach. While other beaches may have better or more sand, higher dunes or other favored characteristics, there is something about the total tropical experience of walking the beach at Sanibel. The combination of magnificent views and a shoreline that brings a new population of shells with every tide is rivaled only by the grace and beauty of the pelicans and gulls in the sky. The dolphins playing in the surf produce a serenity and solitude that is unmatched anywhere. If outdoor sports are your priority, enjoy the three island golf courses and several championship courses nearby. Tennis courts are available at no charge and there are miles of bike paths on Sanibel on which you can explore the Island on the four bicycles provided at no charge. For the nature lover there is the Ding Darling Wildlife Sanctuary offering rare sightings of tropical birds, alligators and other wildlife. There is also The Bailey Tract and Tarpon Bay, which have nature trails, mangrove canoe trails and other interesting exhibits.
