connection Pamplona to Hendaye

Bem,
It is not that clear!
Renfe (Spanish National Railway) on their site:
train from Pamplona till Irun: daily at 11:19 and 19:21, arriving 13:25 resp. 21:32, price EUR 22,00 one way, not on Sunday
see: http://www.renfe.com/viajeros/index.html

But there is other info at: http://www.xacobeo.fr/ZF1.05.tra.Esp.htm

So it is confusing....

It is possible to walk to Bayonne on the Camino Frances in 5 to 6 days, leaving the Camino Frances at Trinidad de Arre about 4.5km from Pamplona. Although this is considered an ancient route, used by the Romans on the Camino Real, it is not a frequently used route and does not have much in the way of pilgrim accommodation until it reaches Trinidad de Arre.
Ruta del Baztan: ± 100km Bayonne to Trinidad de Arre and Pamplona

For all bus times in Spain refer to http://www.alsa.es

My suggestion would be bus from Pamplona to San Sebastian (€14). About 10 buses a day. Check the journey times - some are just 1 hour, others go the long way; 2 hours. From San Sebastian you can take the narrow guage train to Irun, or take another bus.

All public transport is extremely good value in Spain. For a rough rule of thumb €10 for every 100KM will more than cover the estimated cost of a bus ticket. But, the Alsa website above does give good information and exact fares.
