Pamplona to Bilbao by bus

Does anyone know what bus companies go from Pamplona to Bilbao ?
I am trying to figure out how to get from Jaca to Bilbao...I think I will have to go through Pamplona, am I right? Any suggestions are appreciated.

esperanza, have you yet tried Eddie's mention of http://www.Movelia.es ?

It's a kind of conglomeration of cooperating bus companies - like an "all in one" routes/prices/reservations site. Not ALL bus companies are represented though but they seem to show the exact prices that the individual bus companies show on their own sites too so that's encouraging. Check it out!

Have a nice Sunday, everyone! Saludos, MadridMan

Hello to the Board.

Please be aware that if you use www.movelia.es that you need to change the date on your computer to match the date in Spain - Should there be a time/day difference. Otherwise, you won't be able to do bookings.
