In reply to Beat me to it!:
Not sure I would call Pralognan quaint though..
(though the villages further up the Prioux valley are).
To the OP (and as per SamHarr:
Isertan in Pralognan - 5 mins walk to the big crag under the cable car (100 or so routes from 3+ to 7a, Via Ferata de la Fraiche - not very long but really cool (literally) right by a waterfall. Good walking all over the shop from there.
Canada in Champagny le Haut - 10 minutes walk to the Grande Roche crag - ~25 or so pitches 5-6b+, easy via ferrata on this crag too (which sadly traverses a ledge above all the climbing - helmet recommended below...), and a short but sharp via ferrata below the road up to Champagny le Haut (resting sling & crab advisable) off the path down to Champagny. Good walking in all directions...
