I knew about the Shuttle Bus in Key West, but I did not realize that this same excellent service was available in Marathon. You learn something new every day in this business!
The shuttle Bus stops in Marathon a short walk away from Sombrero Dockside Marina. Right beside the Publix Market.
It stops on the Highway in Big Pine and I do not think it is anywhere near a Marina. You can check the website and use Mapquest, Google maps to check.
We are currently sitting at Sombrero Dockside and used the Shuttle Last Year, it is an easy walk.
