Olbia is a ferry port, so you can easily get in by ferry/cruise ship. OLBIA will be one of the ports of call for DISNEY CRUISE LINE's M/V DISNEY MAGIC from MAY until AUGUST 2007.
Beware the way locals drive: racing along the narrow and bendy roads in the hills.
You may encounter poor road conditions, with potholes and open grids. Also the skill of some drivers leaves something to be desired.
