Have always been drawn to funny-shaped, prominent, geological bumps - particularly protruding ones of usually small stature. Quite a few of them are on my lists of hills I want to climb: Eildons, North Berwick Law, Suilven, Paps of Jura, Dun Caan etc. The popular ones such as Pap of Glencoe, Maiden Pap(s), Morven are also stunning. Not actually done very many of them - Dumgoyne/Dumgoyach, Arthur's Seat spring to mind but that's about it for the well-known ones. As Scotland isn't particularly volcanic, or glacial (relatively speaking), we don't tend to get very many impressive ones like other countries, usually oceanic or oriental in origin, do. Would be nice to see if anyone has a favoured pap, regardless of how comparatively small it is.
One of my favourite bumps; visible at certain angles from at least 20 miles away, Dumgoyne:
