The Ladies course at Machrihanish serves this purpose as well. Several holes are pretty flat and altogether mundane, but the set of three par 3s (#1, #3 and #7) are collectively just as good as - or perhaps even better than - the par 3s on the main course, and a couple of the par 4s traverse rolling terrain are quite fun as well.
What I really like about the Ladies course is that juniors have to shoot a certain score on it before they're allowed out on the big course. They can learn the game in an utterly unhurried and unthreatening environment, and only when they're really ready do they graduate to the longer course - although that said, a lot of them like to stick to the relief course!
Cheers,
