Mile Beach unfurls between Seawall Beach to the south and Popham Beach State Park to the north, a slender thread of sand that catches fewer visitors than either neighbor. You reach it via a rutted dirt parking area off Route 209, then cross a short boardwalk through beach rose and bayberry. The shore itself is wide and flat at low tide, revealing dark bands of mussel shells and smooth stones the size of dinner plates.

The Kennebec's outflow colors the water a deep jade on the ebb, and the river current shapes the sandbars into long, rippled shelves. Surf here runs smaller than Popham's exposed break, but the undertow can surprise you—wade in up to your knees and you'll feel the tug of competing currents. Bring a windbreaker even in July; the onshore breeze off Atkins Bay rarely stops.
Behind the beach, dunes topped with marram grass shift slightly each season, and you'll spot the skeletal remains of driftwood logs half-buried in sand. Ospreys nest on platforms across the marsh, and harbor seals sometimes haul out on the rocks near the river mouth at low tide. The beach empties almost completely by late afternoon, leaving you with the rhythmic slap of waves and the calls of herring gulls wheeling overhead.
