I'm in the (very!) early planning stages for our June 2011 Georgia vacation. We'd like to take a day trip to Cumberland Island, using the ferry. We'd probably get off at the stop at Dungerness Ruins, since we'd want to see those. Where is the nearest beach from the ruins? On the map of the island, it looks like you can just walk east from the ruins, and you'll hit a beach, right? Or would we have to bike/walk to Sea Camp and access the beach from there?
