Walk that runs along the coastline. It is in terrible condition for much of the journey. There is a lot of glass on the path and on the planked part there are several sections that are on the verge of collapse. The road runs through part of the Piñones State Forest and passes through several scenic spots, including the old viewpoint that Hurricane María took away.
