Check out this website about the Circumnavigating Florida by kayak saltwater trail. This trail starts at Fort Pickens and runs to Fort Clinch and includes the Keys and is measured at 1515 miles.
This web site has a wealth of information including downloadable pdf maps of the entire route which watertribers should fine very useful since it covers the EC route.
This is certainly something that I would be interested in doing. It is like the Coastal UF but includes the keys which we seem not to speak of much.
Anyway if you are going broke buying maps like me this may help if you print onto waterproof paper. I have 4 lbs of charts that was in my UF gear.
In addition to the maps there is just a ton of information including places to camp, supply, planning map, photos, etc.
Here is a link to the Fort Desoto, Tampa Bay portion of the Trail. It is interesting to see what they have to say about our Launch area and crossing Tampa Bay.
