From the Metalliferous Hills, the ride immediately starts with a nice, long descent that connects Monterotondo Marittimo to the Val di Cornia, proceeding calmly to Montioni.
At the next junction, turn left onto the spectacular "Marsiliana" provincial road, boasting continuous ups and downs through a spectacularly scenic part of the Maremma. The climb to Massa Marittima isn’t too long (about 4 km) but it requires some ability. Massa Marittima, the port to the Maremma, deserves a longer stop, where you can admire its cathedral and town hall and get lost exploring the town’s quaint streets.
From the town centre, continue down the descending Massa Marittima - Accesa “Strada Comunale,” passing through Capanne and La Pesta, to reach Lago dell'Accesa. The descent toward Valpiana, Cura Nuova and Scarlino Scalo (a deviation to Scarlino is possible here) is quite enjoyable. From there, continue towards Puntone and its tourist port.
