6. Roque Bluffs, Maine

So far the list of secluded US beaches has taken you to warm climes, but determined beach fans don't need hot sun and palm trees to feel euphoric. Roque Bluffs State Park in Maine allows you to hike along lovely Englishman's Bay trails that lead to a deserted beach. It may be pebble-strewn but it's still gorgeous in its wild beauty. The North Atlantic is perhaps a little frostier than what your toes are used to, but armed with a wetsuit and that "stiff upper lip" a typical Englishman would adopt, you can still enjoy a swim here, especially at freshwater Simpson Pond, which is marginally warmer.
