Nature lovers and hikers should definitely explore the Groene Hartpad (Green Heart Trail). This long-distance hiking trail leads through the beautiful Groene Hart, a picturesque area in the middle of the Randstad, characterized by vast landscapes, glistening lakes, and winding rivers. For hikers who love sweeping views and meadow birds, the polders are ideal for walking, with their vast meadows bordered by ditches and canals, home to birds such as the black-tailed godwit, lapwing, and redshank.
