Bus From Barcelona to Pamplona
 

Has anyone taken bus or train from Barcelona to Pamplona? Is Enatcar bus still the best company?

It's the ALSA bus.

Thank you.

My mistake. The Alsa bus runs to Madrid and Bilbao. You have to take the Vibasa bus from Barcelona to Pamplona for a direct route.

http://www.vibasa.es/

Vibasa has 4-Barcelona Sants departures for Pamplona daily. The one at 15:15 lists 52 plazas; the one at 15:45 lists 28. That tells me the latter may be aomething like ALSA Supra service, although I can't confirm that.
Sorry, the Vibasa web page is all in Spanish.

Thank you for the info.
