If you are in the Pensacola FL area I would suggest going to Fort Pickens on Santa Rosa Island to view the channel into the Pensacola Harbor. It is part of the Gulf National Seashore and there are fees to cross the bridge to Santa Rosa Island and weekly user fee for access to Santa Rosa Island. At the fort there is plenty of parking areas and public bathrooms. The sea wall is very good for taking pictures from. Good Luck!!!
