There are no motorized vehicles on the island for visitors except in extremely limited circumstances. There is a "Lands and Legacies" Tour which is a five to six hour motorized tour of the North End of the island, and there is transportation to the one hotel on the island. Otherwise you should expect to walk or hike everywhere. When the Carnaige family lived here, they had little electric vehicles which were recharged for them every night.
But I was not sure that I could do the amount of walking involved to see the sights. Regular wheelchairs don't do well on non-paved surfaces - most of the 'roads' are just packed sand. I found on the internet that they had beach wheelchairs. So I made a reservation for one.
When we got to the island, I found that the reservation had gotten lost, but the ranger went to the administration building, and brought me the beach wheelchair. It wasn't like a regular beach wheelchair because it had huge tires like those monster trucks. It was hard to get into as it was tall and tippy. I had to have help - someone had to hold the chair down so it didn't fall over when I got in or out of it. Had I been really disabled, I could not have managed it. I think they had the tires reversed.
It was also QUITE hard to push. You need to have someone really strong to do that.
Seven miles east of St. Mary's Georgia and just north of Amelia Island Florida, Cumberland Island is accessible by a concession operated passenger ferry. The only other way you can get there is on your own boat. I really wanted to try to see Cumberland Island closer than from offshore, so I tried to get a reservation on the ferry. I had no luck - it was completely booked.
So in 2011, I made the reservation well in advance, and finally got to go to Cumberland Island.
SPRING/SUMMER/FALL (March 1st to November 30th) – The ferry departs St. Marys at 9:00 a.m. and 11:45 a.m., and departs from Cumberland Island at 10:15 a.m. and 4:45 p.m.. (MARCH 1 to SEPTEMBER 30 - Wednesday through Saturday there is a 2:45 p.m. departure from the island)
WINTER (December 1st to February 28th) - The ferry does not operate on Tuesdays and Wednesdays, and there is no 2:45 p.m. departure from the island. The two departure times from St. Marys and Cumberland Island remain the same.
The ferry does not transport pets, bicycles, kayaks, or cars.
The ferry ride takes around a half and hour . It runs daily except December through February, when it does not run on Tuesdays and Wednesdays. It does NOT carry cars, bicycles, kayaks or pets. It leaves St. Mary's at 9:00 a.m. and 11:45 a.m. and the island at 10:15 a.m. and 4:45 p.m. From March thru September it also leaves the island at 2:45 p.m. -wednesday thru Saturday. You can make reservations for the ferry up to six months in advance.
