Forte Sperone to Forte Diamante via Forte Puin and Forte Fratello Minore

The route from Forte Sperone to Forte Diamante follows the northern ridge of the Parco Urbano delle Mura above Genoa, in Liguria, Italy, linking a chain of fortifications built to defend the city. Access is by the Zecca-Righi funicular from Largo della Zecca to Righi, followed by a walk to Forte Sperone, where this section begins. No permit is needed, and there is no parking at the trailhead worth relying on, so public transport is the practical choice. The walk covers about 3 km one way with roughly 140 m of climbing and takes about 1.5 hours; the full Righi to Diamante outing, with a return by train, takes 4 to 5 hours. Forte Diamante stands at 660 to 667 m depending on the source. Technically the route is moderate rather than hard because of its length and the sustained ridge walking, not because of steep ground. The surface alternates between military roads, dirt tracks and short stretches of tarmac. Some road sections are narrow with no shoulder, so walkers should stay alert for vehicles. Much of the ridge is open and exposed to wind, with only intermittent tree cover. Landmarks along the way include Forte Puin, Forte Fratello Minore and finally the distinctive star-shaped Forte Diamante, whose position gives long views over the Polcevera valley and the Ligurian coast. Sensible turn-around points are Forte Puin or Fratello Minore for a shorter day. One return option is the Genoa-Casella narrow-gauge railway from the Trensasco stop to Genova Manin, but the line has run reduced service since 2024, so the timetable at ferroviagenovacasella.it should be verified beforehand. There are no refuge huts on this stretch and no dependable water sources, so about 1.5 litres of water per person is advisable. Trail shoes, a windproof jacket and an offline map complete the recommended kit.
