what's the best means of transport?
which is the cheapest? and how much it would cost? and lastly, how long it would take?
thanks so much in advance!
The following ferry companies were running out of Palau:
Perhaps you can check the web for details - I don't know if they go to Cagliari though.
You could take a bus to Olbia (about 1hr, http://arst.sardegna.it:8080/p.jsp?page=page.jsp&idPagina=259&comune=PALAU&idlocalita=626&idlocalita_due=562&Submit=Vai), then a train to Cagliari (about 4 hr, 13.60 Euro, http://www.trenitalia.it/en/index.html)
