As stated
- Bahia Honda is worth the trip
- Dry Tortugas is probably my favorite place down there. Simply beautiful
I do agree scooters are the best way to get around the island however I belive the rental companies state the scooters aren't suppose to leave key west.
The KOA a few mikes away rents pontoon boats, not sure how their prices compare
As others stated it is a long drive from bluewater to st Augustine, it's doable though. I usually make that druventhenother direction, from KOA/bluewater/Boyd's to beaverly beach. Traffic is questionable, early start is a must
