# Grotta del Bue Marino and Cala Luna by Boat from Cala Gonone Boat from Cala Gonone to the Grotta del Bue Marino and Cala Luna, a beach with no road; €42 plus the cave entry, March to October. Fuente: https://www.geocalia.com/en/italy/sardinia/gulf-of-orosei/things-to-do/bue-marino-and-cala-luna-by-boat · Revisado: 2026-11-11 Dónde: Gulf of Orosei The Gulf of Orosei is a limestone wall tens of kilometres long with coves that can only be reached by sea or long trails. This trip combines the two visits closest to Cala Gonone: a sea cave with a walkway and a beach with no road, and lets you choose how long to stay on the sand. ### What the Grotta del Bue Marino is It is a karst cave open to the sea, south of Cala Gonone, in the municipality of Dorgali. Its name, "sea ox", is what the fishermen called the monk seal, which had one of its last Mediterranean refuges here. The guided visit, on foot, follows a walkway through the southern branch, among stalactites and rock chambers. Entry is run by the Dorgali council and is paid separately from the boat. ### What Cala Luna is A beach of sand and pebbles at the foot of a cliff with caves, at the mouth of the Codula di Luna, between Dorgali and Baunei. No road reaches it: you come by boat or on foot along a long trail. The caves at the back give shade by mid-morning. ### Times and departures The boats of the Nuovo Consorzio Trasporti Marittimi Cala Gonone leave the quay every hour, from 9:00 to 17:00, and need a minimum of ten passengers. From Cala Luna there are return trips at 12:30, 15:30, 16:30, 17:30 and 18:30. Times may change depending on the weather and the season, and the ticket office, opposite the quay, announces the day's times. The 2026 fare season runs from 27 March to 31 October. ### 2026 prices Boat Bue Marino + Cala Luna: €42 adults and €21 for ages 3 to 8 (€40 and €20 from 10 to 31 August). Cala Luna only, return: €35 and €20. Cave only: €32 and €16. Cave entry: €10.50 general and €5.50 reduced in spring and autumn; €12.50 and €6.50 from June to September. The consortium warns that this may change. Children under 3 do not pay for the boat; from age 9 the adult fare is charged. ### With children It is a good family outing: a short boat ride, a cave with a walkway and a beach to stop at for the rest of the day. It is cooler inside the cave than outside. At Cala Luna there is no guaranteed lifeguard: keep an eye on children in the water. ### Combine it with If you want to go further, the mini-cruise to Cala Goloritzé reaches the southern coves. If you would rather take the helm yourself, the no-licence dinghy stops wherever you like, and by paddle, the kayak from Cala Gonone reaches the cave and Cala Luna in a day. ## Paso a paso ### Before · Buy the boat and the cave The ticket office is opposite the Cala Gonone quay.
