How do I transfer, by foot, or bus, from GR65 to GR653?

[cete46]

I am on the GR65. I have heard that the passage through the Pyrenees by the "Col du Somport" is superb and would like to try it. How do I transfer from the Via Podiensis (GR 65 from Le Puy) to the Via Tolosana (GR653 from Arles)?

I have thought about that myself. The routes get very close at one point Here's what I'd do:

--Stay on GR 65 to Navarrenx
--Follow the west side of the river south 7-10 km to GR 78(the Voie de Piedmont) near Prechacq-Josbag
--Continue about 10 km SSE on GR 78 to where it crosses GR 653 at Oloron Ste Marie

The trails are on the IGN topo 25 series map.
