There are no food services at Cumberland Island National Seashore and only a few places where you can get safe drinking water, most of which are located at the Sea Camp and Dungeness areas. There are restrooms and water north of Sea Camp, but the water is not safe to drink unless it is boiled and purified (except at Plum Orchard Mansion). Even the safe water has a slight chlorine/sulfur taste to it, so try to bring as much of your own as possible. I drank it and found it not too unpleasant, but it’s not purified drinking water either. If you will be depending on the island’s water, one suggestion is to bring powered drink mix to mask the bad taste. Day trippers should be able to carry enough water for the day. It is the multi-day campers who may need to replenish their water supply.

You can purchase bottled water on the ferry.

All restrooms have modern plumbing and are not portable or chemical toilets.

Restrooms and safe drinking water (unless noted) are located in the following places, south to north:

CARNEGIE LAUNDRY BUILDING
This is not a place to do your laundry if you get dirty during your visit, but a historic building from the Carnegie era. It has been converted into a restroom with a drinking fountain, plus antique laundry washing equipment is on display inside. If you are standing at the entrance to Dungeness Mansion, take the dirt road to the left. About a quarter mile down is the laundry building. Picnic tables are in the yard. Across the road is a large, white building, the former carriage house and stable.
