In reply to Derry:
As others have mentioned there are lots of nice easy long routes in the Andermatt area of Switzerland and the Dolomites as well as the Bregaglia.
Wadi Rum in Jordan is also good for long routes of up to VS (all the Bedouin routes) although they do have a bit more of an adventurous feel to them, with difficult route finding and descents.
The normal route on Stetind in northern Norway is a nice mainly scrambly long route with just one pitch of about severe (quite exposed) pretty fantastic summit. I think there might be some other longs routes in that area too, and you've also got Lofoten close by which has some long easy routes like the North ridge of Vagakallen.
Closer to home there's tons in Scotland- for example you can do all the 5 ridges on Ben Nevis if you want a really long day!
