We stumbled upon this little gem by accident. Once inside we absolutely had a 'whale' of a time! The staff engaged with my children giving them activities to do. There were education films to watch, things to read, things to do and loads to learn. The staff were very helpful with questions and answered well. A lovely way to learn... More

What a great place to sea kayak!!! It's a beautiful pristine wilderness to enjoy with crystal clear water. Shark nursery in the mangroves. Great place for picnicking on many of the islands. Several concessionaires in the area, but Capt. Markus is the best. Great way to spend a day enjoying the natural environment.

We just happened upon this wonderful facility while we were looking for the Fort Zachary State Park. It is a free attraction and is well worth the time to go through this . The short film about the Keys' waterways is beautiful and full of information. The displays about the plants and the animals, as well as the large aquariums... More

Sail in to your favorite island in the afternoon, and watch the sunset with your friends while sipping on your favorite drink of choice. Wait for the tide to drop and get marooned at a sandbar in the Gulf of Mexico for a true experience with yourself. Fall asleep to the sounds of small crashing waves and the sight of... More

The Keys are a long strip that goes south from Miami. Key West is at the end of the road, and is th Southernmost point of the US. It is worth the trip, as you will find a vibrant fun town, that likes to party and watch the awesome sunsets. I recommend the Grand Hotel. This is a tiny hotel... More

Great little shops, many many wonderful restaurants and an island dedicated to marine life and tales from the past Parking can be a problem, but look... More

This is among the best diving America has to offer, in my opinion. Living coral formations, the abundance of marine life and species, excellent visibility (40-60 ft), water temp (75-82), fabulous dive shops with knowledgeable staff. A dive or snorkel at this reef should be on everyone's bucket list, in my opinion.
