accommodation list updated.
call in advance for every accommodation. for beost, gabas and ayous at least 4 days in advance, bearing in mind that gabas and ayous close at the end of the season. ayous has a winter room (and F outside, probably working off season?) but I don't know for gabas. there are two hotels in gabas, too. I couldn't get anyone for beost and wanted to sleep there really badly. it's not advisable to drink directly from the streams on high pastures, because of cows and sheep grazing; at least when they are up there. bring a purifier.
start asking at the TO in lourdes, they might have some maps or other info already. then ask everywhere you sleep and in municipalities, but especially in laruns' TO, it's well stocked.
it's a very beautiful route. I hopped from west to east bank, to see as much of the lovely villages and their fine houses and monuments as possible.
I made it like this: lourdes - asson - arudy - laruns - gabas - ayous - canfranc.
lourdes - asson
you have a choice of chemin de st jacques proper (yellow arrows) or GR which goes via lovely st-pe-de-bigorre (with a shop). asson has only one bunk and two mattresses, the shop is closed on M, W and Su afternoon, but the first bar on the right, on entering the village, stocks a few cans.
asson - arudy
here I haven't seen two waymarkings. after sainte colombe there is a fork for arudy (left) and sevignacq-oloron (right). well signposted. voie d'ossau is now a proper GR with red-white waymarks (but also occasionaly yellow arrows or shells). first peak of pic du midi. arudy is well stocked with bakeries and has a supermarket. the priest in the presbitery will probably say 'mon dieu, jesus, marie!' when you tell him you are going over col des moines.
arudy - laruns
it's still all flat and with a view of pic du midi all the way if the weather permits (it didn't for me, sniff). the official route follows the eastern bank of gave d'ossau, to laruns it's practically all on a minor road. I started on the west side through izeste (afterwards you can hop to the east side at louvie-juzon) and bielle then changed to the east side at the camping in monplaisir - a footbridge to aste-beon. I went via beost and arrouste to laruns, to see them that day.
laruns is a bustling town with a good TO and a good gite. the bunks are very close together but there are walls in between so it doesn't seem so stuffed.
laruns - gabas
the route now avoids almost all of the main road but that means that you go up and down one or the other side constantly, and steeply (a few ropes in one section which can be avoided via the main road). it's really beautiful, passing through some quite enchanting forest. about 5-7h. gite is beyond the village, where the side road to lac bious-artigues branches off. here take care not to go left up the wrong valley!
gabas - ayous
after lac bious-artigues the main route goes left gently up along the broad valley and more gradually ascends to col de moines, passing two shepherd huts which can be used as bivouacs when the shepherd is not there (or even?). firewood and water should be provided (but it's polite to bring some dry wood).
for ayous, turn right up here, zigzaging up to the refuge in about 1h30-2h. the position above a lake (good for swimming) and the view of the amazing pic du midi (and an optional ascent to pic d'ayous above with 360C view of the pyrenees) make it absolutely worthwile. reserve! there's a water pipe outside. you can only sleep, too, but bring your food, there's no kitchen. it opens 15h-16h but you can leave the backpack and go exploring. 3-4h from gabas.
ayous - canfranc
continue from the refuge on a path with yellow signposts due south up past another big lake then down and right up to col de moines. on the other side, above astun, there is an eroded section that can be tricky in the rain. then the road to somport and the path with yellow arrows to candanchu. this part has been badly damaged last autumn by water and landslides, don't know if it's repaired.
from candanchu/ruins of hospital st christine there are now two options. the left one (left on the road across the bridge then left up) is GR 653 with red-white waymarkes and yellow arrows and sticks to the east side of the valley all the way to canfranc estacion, crossing the main road only once. in 2012, a new, more 'historical' route has been waymarked with yellow arrows. this one goes straight down between appartment blocks, crosses the main road at least three times and sometimes runs parallel to it. I didn't find it as nice as the GR.
aw, man, another long post.
