This is the day most people picture when they think of the Costa Smeralda, but put in an order that works: the beach first thing, while there is still room in the car park; a boat and snorkelling in the afternoon, when the beach fills up; Porto Cervo at sunset, when it comes alive, and a dinner with the sea in front of you. You need a car, and it is best to book the boat and dinner before you set out.
Getting there from Spain
Fly to Olbia: from Spain there is only a direct flight from Barcelona. With your hire car, Spiaggia del Principe is about 40 minutes away by the SS125, the SP73 and the SP94.
The day, hour by hour
8:45 · Leave Olbia. Head for Via Romazzino. The beach car park has 25 spaces, and you pay.
9:30 · Spiaggia del Principe. Two arcs of white sand separated by a pink-granite headland, 300 metres on foot from the car. There are sunbeds for hire and a small bar; bring water and something to eat. Stay until after lunch.
15:00 · Snorkelling from Poltu Quatu. Orso Diving Club sails by boat towards the Monaci lighthouse from 15:00 to 17:30: €55 for adults and €30 for under-8s, with mask, snorkel, fins and shorty wetsuit. The boat anchors and you swim to the coves. Book on their website or by phone.
17:45 · Porto Cervo. A few minutes from Poltu Quatu. Stroll around the Piazzetta and the harbour and go up to the church of Stella Maris, by Michele Busiri Vici, with its Mater Dolorosa attributed to El Greco.
19:30 · Dinner at Lu Pisantinu. At Liscia di Vacca, two kilometres away. A terrace by the sea, handmade Gallura pasta such as chijusoni with guinea-fowl ragù (€32) and fish of the day. Open Tuesday to Saturday; dinner comes to more than €90 per person.
22:00 · Return. To Olbia, about 45 minutes.
If it is a Sunday or Monday
Lu Pisantinu is closed. Go back to Olbia and have dinner at Bacchus, the restaurant of the Jazz Hotel, which is open every day.
