Travel advice - Paris CDG to SDJPP

Hi, I plan on arriving in Paris CDG early on Tues 5th June. I intend to travel via TGV to Bayonne, and then via the local train to SJDPP. I have found a TGV timetable on the web that indicates the TGV only travels CDG - Bayonne twice weekly (Fri and Sun), but another one that shows daily travel but only at 7.39 and 1344 from the airport station, and I'm sure that my earlier internet research showed reasonably timed travel to Bayonne. A PC glitch will not let me view the actual SNCF TGV website timetable anymore. Can anyone offer any local knowledge as to the TGV or other rail frequency? If the TGV is not an option, what would the best rail route be?

Thanks for the flight advice. I have had the CDG to Biarritz flight in the back of my mind for some months as a contingency, but my first preference is still via rail to SJPDP, both to see a bit more of the countryside, (albeit at a very accelatered rate of KM on TGV) and also to break up the day long flight from Oz. The station transit in Paris is something I want to avoid, based on friends who have travelled through there before, so I may well end up changing my plans and flying to Biarritz instead.

Again, if anyone has recently travelled by the rail route I'd like to hear their impressions.

To 'The walk' - I'm happy to start out with you. I'm travelling over solo, but based on all the previous posts I had no doubt that a quick look in SJPDP for persons with a backpack, shell and walking stick would point me in the right direction. Flights going to schedule, I'll arrive at CDG around 0600 Tues 05 Jun, although some last minute flight shuffling may have me arriving at the same time 4 days earlier on Fri 1st June. I have 2 months off work, so am not exactly pushed for time.
