Favorite by the adventors of the summer, this is one of the most suggestive paths of Marettimo. The path, which is beaten and paved, winds along the coast for four and a half kilometers, in a fascinating ups and downs, bordered by fragrant Mediterranean vegetation. Along the way, you will come across a natural water source and overlook incredible overhangs over the sea. Crossing the Camel rock, the path reaches the isthmus that leads to the promontory of Punta Troia and the castle which has the same name, once prison. In fact, the Bourbons used it to confine political prisoners in the dungeons. This last stretch of the route is perhaps the most critical, because it is characterized by particularly steep descents and climbs. However, once you reach the top, you can enjoy a splendid view of the coast of the east side of the island and the horizon, where you can see Favignana and Levanzo. The Castle can usually be visited in the summer. As well as the Monk Seal Observatory, which is located there.
