Olbia (20km from the Dive Centre) is the closest arrival and departure post with many airlines, and navigation companies. The airport is also connected by the low cost company EASYJET and from 2017 RYAN AIR but many airlines fly to and from Olbia so it is best to visit the airport link GAESAR. Ryan Air also flies into Cagliari (connected by train or by car in 2.5 hours) or into the closer town of Alghero on the west side of the island (about 1.5 hour drive).
If you arrive by car/boat you can reach the close seaports of Olbia, or Golfo Aranci (from various Italian locations) or, further away, Porto Torres (from Genoa, Barcelona, and Marseille). Boats also arrive from Bonifacio (in Corsica) to Santa Teresa in Sardinia. You can check the link for updated connections and reservations TRAGHETTIONLINES.
From Olbia we are about 20 or 25 minutes by car: take SS125 (left/South as you leave the airport) and drive past a few small towns the last being the little town of "Monti Pitrosu" till you see the sign for CAPO CODA CAVALLO. Enter that road and you will see a large AQUARIUS sign as you enter the intersection. Exactly 4km later you will see us in the left corner (also the entrance of "le Farfalle 2").
From San Teodoro follow SS125 for about 8 km till the sign for CAPO CODA CAVALLO. Enter that intersection and follow the road for exactly 4km until you see us on the left (also the entrance of "le Farfalle 2" residence).
