La Maddalena Archipelago Tour
Must-DoIconicDepart from Palau to tour the archipelago — Budelli's pink beach (viewed from the boat; landing banned), Spargi's crystal coves, Santa Maria island for swimming. The water transparency here is unmatched in the Mediterranean.
Gulf of Orosei: Cala Luna & Cala Mariolu
Must-DoFrom Cala Gonone, boats visit the string of spectacular beaches along the gulf — Cala Luna (the crescent cove), Cala Mariolu (white pebbles, turquoise water), and Cala Goloritzé (the limestone arch). Most beaches have no road access.
Asinara Island National Park
Hidden GemA former penal colony turned nature reserve off Sardinia's northwest tip. Boat from Stintino, then explore by electric bus or bike. White donkeys, crystal beaches, and almost no tourists. A true hidden gem.
Private Sailing Charter: Costa Smeralda
LuxuryCharter a sailing yacht from Porto Cervo or Olbia and explore the emerald coast's hidden bays. Lunch on board, swimming at celebrity coves, and sundowners watching the sunset over La Maddalena.
Grotta di Nettuno: Alghero by Boat
FamilyBudgetA scenic boat ride from Alghero port to the Neptune's Grotto at Capo Caccia — a massive cave with an underground lake. The boat approach under the cliffs is dramatic. Alternative: 654 steps down from the cliff top.
Our pick
The Gulf of Orosei tour is the single best boat day in Italy — five inaccessible beaches, each more beautiful than the last. La Maddalena is a close second.
