You cant stay up at the top at Portalet as its in the national park, as said you can stay further down at Fabreges by the lake or further up you can shoot off the 934 down the west side where you find a stream and foot bridge, just above the boulder field.
We stayed at both in mid August, the lake side at Fabreges was packed, i tried to count all the motorhomes and gave up at 150 , it was quite a sight.
Whats the fuss about Jaca? drove through it didnt even bother stopping, did we miss something?
