  • Best place! Beautiful beach, Amazing views
    Definitely recommend!

  • The most magical place ever. You can make it a quiet tropical paradise or blast the cross island music and feel the private island party ( note from the widows walk at night this is an experience). The hosts are amazing, we had a private sunrise yoga class followed by massages (possibly the best in my life). Fishing off the dock was almost surreal, always fish there. We picked up live shrimp at the marina and just pulled tarpon out of the water like blue gill! A manatee swam by, a sting ray, lobster were crawling in the rocks ( to small to get), saw an iguana go for a swim and the hermit crabs were a blast! The west side of the island was the best for snorkleing very pretty. The boat , snorkling and water sports equipment rhat came with the island were a 10! Paddle boards floats, masks, fins snorkles, tubes for behind the boat! And the property itself! We stayed here 30 years ago, and it is more beautiful now than ever. It does not have AC , but the fans keep it cool. The outside kitchen, was a great place to cook and hang out. The house is built like a great old wooden ship, and you feel as if you are in a Hemingway novel! Amazing place!

  • This was our second visit to the seabird key and we rarely visit anywhere twice. There were so many family activities that we really didn’t have reason to leave. The beach, kayaks, paddle boards, fishing, boating, tubing, snorkeling, hermit crabs were all there! The outdoor kitchen and bar has forever spoiled us because indoor cooking is not nearly as fun. We would crank the tunes and cook together while the kids would play nearby. We cooked many delicious meals. The beds were comfortable. Concierge extremely helpful and always available. My family can’t wait to return:)

  • Beautiful & peaceful! The experience exceeded all expectations. Weather in January was perfect. Host, managers & owners are a delight!

  • This island get away is magnificent because of the wonderful natural resources it makes readily available to it's guests. The beach is beautiful, and offers both sun and shade. The docks offer fishing and views of spotted eagle rays, manta rays, sharks, eels, etc. The shallows surrounding the island, in the day time provide swimming, kayaking, etc. Having your own boat to make runs to groceries and bait is very convenient. The house itself is a beauty well designed for adults, and children who dont need rails on bunk beds. The two kitchens offer relaxing options for dining indoors and out. Finally, the landscaping fits well with the natural environment, using mostly native plants, and it is well maintained. The trails all over the acreage allow quiet spaces to watch for birds, and spend leisure time. It is a very unique opportunity apart from the usual hotel, or busy town neighborhoods of Marathon itself. Best of both worlds actually, beauty, privacy, and nature apart from the crowds, but close to convenience.

  • Exceptional island getaway! Our two families with children ranging from 3 to 17 had an amazing week at this one of a kind house. The pictures do not do justice to how unique the house is and beautiful the island truly is. We spent the majority of our time either enjoying the private beach, using the kayaks, SUPs, boating around or playing games in the evenings after making dinner in the outdoor kitchen. This was one of the most well-stocked houses I’ve stayed in, which was much appreciated given the location. There was plenty of space for everyone to spread out, but also great common areas that lent itself well to family time. The weather was perfect - high 70s to low 80s during the day and upper 60s to low 70s at night. Note - I would probably avoid the peak summer months as there is no A/C and I imagine the heat and mosquitos could be pretty unbearable. The property manager, Adam, was wonderful to work with and make check in a breeze. Can’t say enough great things about this experience and we all look forward to returning in the future!

  • Seabird Key is such special place. It is not only beautiful, but so well thought out. You have everything you need right on the island. We LOVED the outdoor kitchen and deck. Our entire family loved watching the hermit crabs around the deck, and our grandsons were especially entertained by them. We fished right off the dock , swam off the dock, relaxed at the beach and spent a lot of time on the backside of the island, kayaking, paddle boarding, and just swimming and floating off the dock there. It was always calm there, and our young grandsons(4 and 2) loved it. The location is perfect for boating with easy access to Vaca Cut. Carly and Adam were so easy to work with and so helpful. They bought groceries for us and had them put away before we arrived. It was wonderful! We had so much fun and nobody wanted to leave, but we will definitely return.
