Depending on your flight times, you could also consider a train from Gare Biarritz. There are buses from the airport to the station (or you could walk). You can check the times here: https://uk.voyages-sncf.com/en/#/

The train is a few euros more expensive, but it's faster and a bit more comfortable than the bus. I've used both and have no complaints about either.

Buen Camino!

Stay on this bus til u get to Hendaye train station- about 45 mins. as people will be getting off and on all the time. When u get iff walk down a wee bit and u will see Euskotren station- not inside main station. Euskotren will take u two stoos to centre of Irun and Albergue is a 5 minute walk down from there. Buen camino but a lot if people on the Norte at moment!

Good advice @Lavdrum, it can be difficult to know where to get off that bus when it's approaching Hendaye.

Another option is to walk across the bridge from Hendaye to Irun - purely for the idea of walking from France into Spain.
