On the northwest side of the island is 2,500 feet of both developed and undeveloped areas. Once gulf front, in recent years a sand spit known as Sand Dollar Island has formed, which means the stretch especially at the north end has become mud flats—great for birding. There's plenty of powdery sand further south and across the lagoon that draws a broad base of fans flocking there for its playgrounds, butterfly garden, volleyball nets, and kayak and umbrella rentals. Beach wheelchairs are also available for free use. The Conservancy of Southwest Florida conducts free educational beach walks at Tigertail Beach every weekday from 8:30 to 9:30 from January to mid-April. Amenities: food and drink; showers; toilets; water sports; parking (paid). Best for: sunset; walking; swimming.
