The retro, nautical city of Marathon encompasses a collection of islands in the middle of the Florida Keys including Knight's Key, Boot Key, Key Vaca, Fat Deer Key, Long Point Key, Crawl Key and Grassy Key. As “The Heart of the Florida Keys,” Marathon boasts a wide variety of recreational water activities including dolphin swims, diving, snorkeling, spearfishing, jet-skiing, kayaking, paddle-boarding, boating, and fishing. Marathon offers just as many land-based adventures as it does activities on or in the water. Explore the preserved home of a 20th century settler family at Crane Point, hike Crane Point Hammock and Nature Trail, and view one of the last untouched tropical hardwood hammocks in the Keys at Crane Point Museum. Enjoy a delicious meal at one of Marathon's many waterfront restaurants, visit Curry Hammock State Park, and tour the area's railroad history at Pigeon Key Island. Marathon is also home to a variety of animal interaction opportunities: learn about stingrays at Aquarium Encounters, dolphins at the Dolphin Research Center, and sea turtles at the Turtle Hospital.
