Ailefroide is way more than 1 or 3 hours drive away, more like 5-6. Blockheart contains details of a few odd (ie one or two) boulders locally which may or may not be any use depending on your grade. Col du Montents and Vallorcine on the French Swiss border to Chamonix are in a beautiful location with some hard bouldering but mainly you'll want to be giong away for the weekend to sustenpass, cresciano, chironico and magic wood, all within 3-4 hours drive you lucky ******.
