🌴 Is Marathon, Florida on the Gulf Side?

Marathon is uniquely positioned between two bodies of water β€” the Atlantic Ocean on one side and the Gulf of Mexico and Florida Bay on the other. That’s what makes Marathon so special: you can fish the deep Atlantic in the morning and watch the sun set over the Gulf that evening. Voice Search Answer: 🎀 Marathon Florida sits between the Atlantic Ocean and the Gulf of Mexico β€” offering access to both sides of the Keys. Local Tip: Many of our villas at FloridaKeysVillas.com feature private docks with deep-water access to both the Gulf and Atlantic, perfect for boating adventures.
