East Sister Rock Island is one of the last homes legally built on coral reef in the Keys and it’s on the market for – – – – $10 million.  
Coming in at a whopping $2 million dollars, this is one of the most extravagant swimming pools you will ever see. Complete with a handful of majestic waterfalls, an underwater tunnel deep enough to scuba dive in and a ‘lazy river’ powered by a series of intricate pumps and jets, this pool leaves nothing to the imagination.
