You will have a tough time getting back to normal life after taking a beach vacation to Marathon. This is one of the few parts of the Florida Keys which has a gigantic Beach Park. The beach sand to build the beach area is brought in by the ship load and then pumped in through pipes to the shore. This is an outstanding Beach Park, and a top10 Florida Beach.
This park was remodeled and made just perfect for a family day by the water. Bring your snorkel mask and you will see plenty of fish cruising around. There is a nice Playground area, bathrooms, outdoor showers, and plenty of beach parking.
I would call this the secret beach of the Florida Keys. Not that many people take the turn off the Overseas Highway and head down Sombrero Beach Drive. At the tip of this scenic roadway is this fantastic Beach Park.
