Try the Tib website, it has a route planner.
There are various routes, all require bus changes.
You need to get a bus to Inca and then a bus to Campanet.
Good Luck
I'm fed up of hiring shiny cars and then parking them miles from my house for fear of someone tappng the mirror and blowing my insurance deposit. I really want a banged up clio or berlingo but I cant be bothered so next trip here I'll get a transfer (arriving 11pm so bus is out). but then I wont be able to go bargain hunting...
