Leaving piazza Mario Cortesini in Orbetello, following the signs for Monte Argentario and Porto Ercole. Ride on the bike path that follows the S.P. 161 right in the middle of the Orbetello Lagoon. After 2 km turn left in the direction of Porto Ercole and Cala Galera, taking the S.P. 2 for Porto Ercole. You cross the fork for Cala Galera and after a slight incline you come to Porto Ercole (6.2) and its small port. The road skims the entrance portal to the historic town center, the Don Pedro hotel, and with a sprint uphill the S.P. 66 "Panoramica Porto Ercole" leaves the town and immerses itself in the countryside, among pines and Mediterranean shrub, offering a beautiful view of the coast and Isolotto. The road climbs gently for about 4 km, until reaching a hilltop (10.5) where a very steep downhill run begins.
A few hundred meters later, in front of the barricade of the old road (closed due to a landslide), you continue to head downhill until reaching a fork: keep right towards the parking lot, ignoring the signs for "Il Pellicano". You’ll cross a short dirt track and then head up a steep asphalt ramp which then returns to dirt track after 500 metres and proceeds less steeply up to the hilltop (11.9). You begin to descend, bypassing Punta Avvoltore. Soon after the wide but rough road begins to ascend again; at this point the view of the coast between Punta Avvoltore and Punta di Torre Ciana is superb.
