Unique Camping Spot
What an amazing spot to spend a few days! You can get here by personal boat or on the NPS concessioners' ferry. We paddled in a canoe from Crooked River State Park to Cumberland Island, so that certainly added an element of remoteness.
When you arrive, be prepared to load your items into a cart in order to get them from the dock area to your campsite. The campsites are probably a 10 minute jaunt from the park office on the island (near where you dock) and doesn't take too long if you're able to load everything in one trip.
The wildlife is abundant so be sure to proactively store your food. The raccoons are active all hours of the day and night so be sure to lock things up (including securing the lids to your coolers) if you stray away from your site. The beach is a short walk from the camping area and is a great place to spot more incredible wildlife and a magnificent sunrise.
While we were there we saw wild hogs, armadillos, raccoons and many other small mammals. This campground is situated in the perfect location to explore the island. I would recommend getting an early start to the day so to have the island to yourselves before the first ferry of the day arrives. There's something special about being one of only a handful of people there overnight.
There are cold water showers and access to fresh water at Sea Camp as well.
