Kurt, check out Googlemaps .com, zoom in on your destination on the coast sand bar and then switch to the satelite photo image, you will see all the detail.
The sandbar route is worse than I expected . there is virtually no road , for a long stretch. You just have to get a boat across a bit of water and then navigate the track between the palm trees. Do you want to manhandle a heavy bike in sand with hot weather ? Me neither thats why i turned tail with my GS1100 ?
