Sanibel Island has long been regarded as both one of the top shelling destinations and one of the most congenial little islands in the world. With no highrises, and plenty of nature to explore, it is not only ecofriendly but also possesses luxurious sophistication along with spectacular water views. Down a private road near the scenic coastal park, a 4,500-square-foot bayfront estate captures the magic fully. Dolphins, manatees, and shore birds cavort off the seawall, enlivening thrilling panoramic views that stretch from the main rooms out across the water to the bridge. Two dens, a granite kitchen, gameroom, four bedrooms, and four and a half baths lend similar atmosphere. An elegant master wing is reserved for the owners. Beyond are a five-bay garage and a focal point of the house—a dramatic lanai overlooking a cascading spa and free-form pool surrounded by manicured palm-studded lawns and the sparkling bay.
