You set out early, board a boat in Alghero harbour, skirt the cliffs of Capo Caccia to the mouth of the cave, eat seafood facing the sea on Piazza Sulis and walk the bastions before heading back. ## Getting there from Spain There is no direct flight from Spain to Alghero. Fly to Olbia (OLB), which has a direct flight from Barcelona, and hire a car at the airport. From Olbia to Alghero it is about 140 km, around two hours via Sassari. In Alghero park on the seafront or in a car park outside the walls: the old town is a restricted-traffic zone and everything in this plan is done on foot. ## The day, hour by hour 7:30 · Leave Olbia. Two hours' drive. 9:45 · Boat to the Grotta di Nettuno. Navisarda boats leave from the Banchina Dogana, the quay below the walls, with one departure an hour. The crossing takes about 40 minutes and passes Capo Galera, Punta Giglio, the cliffs of Capo Caccia and Foradada island. The visit to the cave is guided and lasts half an hour: Lake La Marmora, the Reggia hall, the Grande Organo. The entrance fee, €18, is paid separately from the boat; buy the time slot in advance on the cave's website. You will be back in the harbour early in the afternoon. 13:15 · Lunch at Il Pavone. On Piazza Sulis, ten minutes' walk from the harbour, with a veranda over the sea. Seasonal seafood, three-course menu at €50 or four courses at €65. Book by phone. 15:30 · Walls and old town. From the Sulis tower you follow the Marco Polo, Pigafetta, Magellano and Colombo bastions to the Maddalena tower, and enter the old town by the cathedral of Santa Maria and the church of San Michele. Free. 18:00 · Back to Olbia. You arrive around 20:00. If you want to watch the sunset over Capo Caccia from the bastions, stay the night. ## Cómo llegar ### By car From Olbia to Alghero and back, about four hours in total; park outside the walls. ### Without a car Inside Alghero you do not need one: the boat leaves from the harbour and lunch and the stroll are on foot.
