Flying to Biarritz late Thursday 6/9

I don't have any inside track on this Micht and maybe someone else does. But... the tripadvisor Bayonne message board suggests a taxi will cost 15 to 20 Euro. I do however see a bus on my google maps lookup just now (excuse me if there are more obvious sites to use, I'm not the smartest smart phone user) that leaves Chassin at 22:01 arriving at Bayonne 22:19. That's on the Thursday. It's a 1.6 km walk (20 mins) from airport to that bus stop. That's got to be way cheaper than a taxi though not so convenient. I can't see a cheap stay local to the airport. As you might expect. But there are good deals at Bayonne through Airbnb (circa 30-35 Euro) that are close to the centre and train station and hostels too I understand.

Unfortunately, there are no buses running from Biarritz airport by the time your flight arrives (!) The nearest one stops 1.5 km away, and you'd never find it in the dark.

I would suggest spending the night near Bayonne railway station (always cheaper than near the airport, plus a good selection of places to eat and plenty of cheap hotels/AirBnB/hostels) but you'll have to get a taxi. I doubt you'll be the only person in that position, so look for fellow walkers in the arrivals hall and suggest a taxi share. It's about a 15-20 minute journey.

Good luck!
