Fine ocean and Gulf views appear as soon as you hit the Marathon area on the Long Key Bridge. As you leave Layton and cross the bridge you’ll feel like you’re driving out to sea. Between Long Key and the first little Conch Key is the point where the Atlantic Ocean meets the Gulf of Mexico. There is actually some sandy shore, so people like to snorkel and or scuba. There are pull-offs for drivers on both ends of Long Key Bridge. It’s the second longest in the Keys.
