On a recent visit abroad (there aren't any hills in East Anglia) I asked about flying over the local hills (not that I wanted to, I was just curious about what precautions they took).
"We don't," was the answer. "But if we really want to we'll do so only on a day with exactly the right weather, and we'll be 2,000' above the peaks." This was in 172s, not microlights.
