Hi do you mean Arricife?
We got a bus from PDC last year to Costa Teguise, which pass by/through Arricife, so you should see buses with either Arricife or PDC on at most bus stops. Not sure where the bus station is in Costa Teguise but we got off when the driver said he was going no further! Wasn't a bus station though.
As for prices I cant remember exactly what it was, but it was not very dear at all and a good price for us, so to Arricife it wouldnt cost much at all.
Taxi may be more but will e quicker. Arricife is near to Costa Teguise.
Apologies after all this if there is a place called Arrietta and I've babbled on about Arricife!!
