3BR, 2BA, sleeps 8, 6000 sq.ft. East Sister Rock Island is located 1/4 mile off the Atlantic shore in Marathon Key, Florida. On the private island sits a dream come true getaway home with 5000+ square feet of living area including a 2700 square foot veranda, boat dock (fishermans dream), helicopter launch pad and many more surprises. The home was built on a coral reef (a diver and snorkler's dream) and is complete with every necessity except air conditioning, which isn't needed due to the cooling trade winds during every season and over a dozen sliding glass doors. East Sister Rock Island is run off of nature's energy. Wind and solar panels power the island. The home has a pool, outdoor shower, satellite TV, fireplace, and BBQ grill. If all that isn't enough, you can go fishing on the 21' Carolina skiff, use of which is included with the exchange!
