Navisarda

Navisarda is the shipping company that has been running the boat line to the Grotta di Nettuno from the port of Alghero the longest: according to its website, more than forty years of daily departures. Its boats leave from the Banchina Dogana, on the harbour promenade, beside the walls of the old town, and tickets are also bought at the Cala Dragunara landing stage, inside the Porto Conte Park.

What they do

• Line to the Grotta di Nettuno. One departure every hour, every day, until 31 October; the cave's website puts the start of the boat season in April. Timetables change depending on the month. The crossing lasts about 40 minutes and skirts Capo Galera, Punta Giglio, the cliffs of Capo Caccia and Foradada island. The boats carry up to 240 passengers.
• Day mini-cruise. With the Punta Giglio, an 18-metre boat limited to 45 passengers: it leaves at 9:30 from Alghero harbour, stops at coves on the coast towards Capo Caccia and returns around 17:00.
• Mini-cruise with snorkelling, to see the seabed of the area, and discounted outings for school groups.

What you need to know

The boat ticket does not include entry to the cave, which is bought separately with a visit time on the official Grotta di Nettuno website or at the harbour ticket office. Navisarda does not publish its prices on its website: they are seen when booking online, in its booking system, or asked by phone. If the sea is rough, the cave closes and the boat does not run the line: call before going.
