Although nowhere near requiring any sort of 'rating', the old 09/27 on St Marys, Isles of Scilly was 'interesting'. The first part of 09 was grass, with asphalt on the 'hump', turning to concrete for the downhill part. Conversely, 27 started as concrete, with grass for the second, downhill, portion. If you hadn't stopped by the time you got to the top, then go-around. The hedge at the bottom end was a graveyard for several aircraft. Even if not badly damaged, they were a write-off due to the very high costs of getting them recovered to the mainland for repair.
Even now, being all asphalt, 09/27 takes some 'thinking about'. First-time visitors should use 14/32 and a low approach and go-around is usually recommended to 'get your eye in'. It's not a chore, really, as it's another opportunity to look at the drop-dead gorgeous scenery.
