Private Island ~Oceanfront-Fishing-Diving~ FL Keys

Staying at East Sister Rock was truly a one-of-a-kind experience. The island offers the perfect blend of adventure and relaxation, all while being completely off-grid in paradise. The 360° views are breathtaking, with the ocean waves and gentle breeze flowing through the house, creating an incredibly serene atmosphere.

We spent our days exploring the vibrant marine life around the island—fish, manatees, stingrays, and even sharks made every swim an adventure. Heading out in our boat was another highlight; we had an awesome time fishing, lobstering, and exploring the beautiful Atlantic waters.

 A special shoutout to our host, Wesley, who was a fantastic communicator and was available 24/7 to ensure we had everything we needed. 
If you’re looking for a unique getaway that’s both adventurous and peaceful, East Sister Rock is the place to be. Can’t wait to return!

A Slice of Paradise - Off-Grid Adventure at East Sister Rock

We have stayed at this Paradise for 3 years in a row and hope to continue for another 20! East Sister Rock Island is the perfect get away for seclusion, relaxation, and simply enjoying the beauty that is our natural Florida. Wes has always been more than accommodating to any request or help we have needed, and responds nearly immediately when you reach out to him. The mote around the island is perfect for those whose want to enjoy snorkeling, but are hesitant of open waters, we have found lobster, conch, eels, puffers, octopus, sting ray, manatees, and thousands of reef fish for people of all ages to enjoy. Just outside the mote provides ample opportunity for spearing and catching your daily protein. Sombrero Reef is a short boat ride from the island and is by far the most stunning reef around. Bring your boat, your rods, and your gear. Conveniently located near shopping, grocery, and restaurants for when you need to revisit the real world. This stay is more than worth the cost, the recharging that we get when we visit is priceless, can't wait to get back next summer. Thank you Wes for everything, you and your property are amazing.
