At the southern end of the great arc described by the Golfo degli Spalmatoi there is a small cove with a concrete dock; from here begins a staircase that goes up the cliff and leads to the trail that, after some curves and a long straight path, ends at the Faro at the Grottoni, about 600 m away. Around the landing there are traces of the cableway that climbed the reef from the sea to feed the lighthouse keepers; some of the structures are precipitated at sea and can be seen a few meters deep.
From Cala Maestra: 90 minutes.
Access to the cove through the trails is allowed only if accompanied by a Park Guide; the prohibition is not valid for residents of the island of Giannutri, for homeowners, renters and guests (these categories must apply for a special pass to the Park).
