Into Obla airport in season there are many low cost airlines however the most dominant is easy jet. Olbia airport is a 30 min drive from the apartment; there is another airport on the Island that can be used in Algero (Ryan air flies there) however it is a 2 -2.5hr drive. You could also catch the Ferry from main land Italy which adds a nice variation to your trip and then either take your car, hire a car or catch a bus (again about 30 min drive from the terminal) the bus will go from Olbia centre and would take as much as 2hrs so be prepared to sit for a while. Moby lines would be our ferry company of choice.
