Aye, Luchon (where the bottom lift station is) is A Quick Release’s base so they know that mountain like i know the veins on my knob 😉 There is stunning riding around there, not just from superbagneres but all round. It just lacks the connected lifts of the alps.
We did an uplift on a wednesday but that was august not september. Used mainly unmarked trails to get down though, Ian mentioned it’s not the easiest to navigate and often a fair bit of fire road to get down, the bike park stuff didn’t look too good but what we rode had some ace bits in it- like broon troot, except it went on forever, was how I described it, steep and woodsy and loamy.
