Yep – I would have thought them same about Les Arcs too, but the ‘cautious’ ones were scared shitless by a particular trail vid which I can’t find a link for
They have a point, you’d have to be out of your mind to take them down la varda… It’s not in the park so doesn’t have a grade but I awarded it a Holy ****. Awesome trail but, yeah.
Not sure how ideal Les Arcs is for your mixed group really- it’s a great hub, with the incredible awesomeness of Pila and La Thuile, the relatively UK-trail-centrey lower-quality-high-volume of Tignes, tons of I-would-never-find-anything-without-a-guide up above Bourg and at Sainte Foy, Val d’Isere which I’ve never made it to yet…
