Yes indeed. Earlier in the season, could be some trickiness in the snow approach on the south end.
Continuing north from Aig Crochues on the ridge toward Col des Dards and Aig Belvedere ...
many authorities say there's a mandatory abseil near the Col, but I did it with some thoughtful down-climbing, then continued up on the ridge toward Belvedere.
I was told that the SE side of Aig Belvedere has bad rock, so I traversed around to the NE side and went to the summit that way. Finishing down the N or NE face had lots of thoughtful scrambling moves. So next time I'd more likely descend the SE side more directly toward Refuge Lac Blanc.
Continuing the below-4000m theme ... the E->W traverse of the Aiguille de la Vanoise has one of the most sustained narrow ridges anywhere (with one fixed-aid move at its W end), and constant views over big glaciers and fairly dramatic peaks.
Below 3000m ...
the Vercors + Chartreuse + Bauges + Aravis massifs are full of long ridges and ledges ("sangles"). My current favorite is N->S traverse of the "Aretes du Gerbier" SW from Grenoble - (I wrote the English-language description on c2c, which corrects the mistaken claim of a mandatory abseil at the S end). For a much longer "sky run" make the ridge farther north at the Col Verte.
Mont Charvin S-N traverse in the southern Chaine d'Aravis is great (with lots of cables).
. . . (and I'm also psyched to try ridge setions between there and N toward the Col des Aravis).
N ridge of the Arcalod is also a worthwhile "sky run" with a couple of short cable sections: Make the ridge lower farther N at Pas de l'Ours - and then return down the same way - (instead of descending the slippery E face to reach a boring non-ridge trail return).
