The island is one of Long Island's south shore outer barrier islands, approximately 31 miles long and varying between 0.1 mile to 0.25 mile wide. Fire Island passes through southern Suffolk County, and is southeast of Long Island separated from the main land by the Great South Bay. Fire Island offers a collection of wonderful communities graced by miles of beach, undisturbed ocean views, a lively nightlife, rolling boardwalks, salt-air breezes and magical sunsets. Even though the lifestyle is casual, this area offers fine dining and first-rate services. Wildlife is abundant, and the rich geological history of this area that began with glacial activity is a fascinating study. Attractions include the historic Fire Island Lighthouse and museum and the Fire Island Summer Club for the rich and famous. Interesting homes and estates dot the island, providing housing opportunities for those who want to settle permanently into one of the greatest natural beach communities on the East Coast.
