Start out in Navarre and go across the Navarre Beach Causeway to Pensacola Beach. Turn right and head down Gulf Blvd along the water. When you get to the giant beachball hang a right and go across the bridge to Gulf Breeze. Then across the 3-Mile Bridge (Pensacola Bay Bridge, but everyone calls it the 3-Mile Bridge) into Pensacola. Take a left onto Bayfront all the way down to Barrancas. That changes in to Gulf Beach Hwy then Sorrento. Take that all the way to Perdido Key. When you get to Alabama, stop at the FloraBama and have some beers and oysters! It's about 50miles one way.
Seriously, you need to go to The 'Bama while you are there.
