From the many vantage points around the island you are likely to see all kinds of wildlife including dolphins, sea turtles, manatees, pelicans, parrot and angel fish along with a variety of birds.

As evening approaches you will see some of the most beautiful sunsets in the Florida Keys as you look west into the Gulf of Mexico.  Enjoy the ocean breeze while sipping your favorite drink and join the keys tradition of toasting the sunset as the sun melts into the distant water.

This site is truly a get away from it all. This exposed fossilized ancient reef is foundation for the island so little worry of the island washing away. You can enjoy wandering the paths through the mangrove trees, fishing from the dock, or snorkeling in the crystal clear waters around the island. A grill and picnic table for a tropical picnic in the ocean breezes off the Gulf waters is welcoming. Kayak or paddleboard around the island and enjoy the scenery.

This property has been very successful as a vacation rental in the past and boasts great projections for the future.  Once the housing structure is rebuilt this island will once again be popular for the news media and home shows on tv.  It's been amazing the free marketing this island has received in the past.
