The two ditches form the central part of the lagoon, that is bounded by a litoral dune string. At Barrinha de Esmoriz's surrounding area, there are pine-woods (at South), humid/ripariam forests (at East and South), sand-dunes and beaches (at West), agricultural landscapes (at North, East and South), a plateau with crawling and shrubby vegetation (at North) and buildings (at North, East and South).
