Beside its new concrete counterpart, the old Seven Mile Bridge juts into the sea like a giant fishing pier inviting anglers, walkers and nature lovers to enjoy one of Florida’s most scenic and historic vistas. Marathon boasts a modern airport and some of the best fishing, diving and water activities anywhere in the world. This is Marathon, the "Heart of the Florida Keys.” Marathon has blossomed into a small city centered on the island of Vaca Key at the midpoint of the Keys island chain. It boasts homely resorts, luxury accommodations, and the conveniences of a modern community. At the same time, Marathon has retained the charm of its roots as a 19th-century fishing village.
