Nhật Lệ beach sits right on the edge of Đồng Hới - now in Đồng Thuận and Đồng Hới wards of Quảng Trị province (formerly Đồng Hới city, Quảng Bình) - only about 1-2 km from the old city centre. The beach runs for about 2 km where the Nhật Lệ River meets the East Sea, with fine white sand, blue-green water and a gentle slope out to sea.
Its biggest advantage is location: few beaches in Vietnam are this close to a city centre, and you can watch both sunrise and sunset from the same stretch of sand. It's often described as one of the prettiest beaches in north-central Vietnam, with a fairly undeveloped, low-key feel compared with big resort beaches.
