I follow an excellent list here in the UK, called the Marilyns. These are "relative" hills that must be a minimum of 150m (approx 500 feet) above their surroundings on all sides. This produces a superb variety of hills and mountains for all ages and abilities.
If anyone is interested in walking the hills and mountains in England, Northern Ireland, Isle of Man, Wales, and of course Scotland, then please visit my website http://tomread.co.uk - here you will find an index of all the hills I have done with webpages containing all the stories and photos - 313 different summits and over 1400 hill reports so far.
Hopefully it is of interest. http://tomread.co.uk and click on the "SOTA" link on the left hend menu pane.
This summer my son and I completed another country - by climbing all the 5 Marilyns on the Isle of Man! That was nothing really. But in 2012 we did completed all of England, which was a more substantial achievement.
We are about halfway through Wales and Northern Ireland (Irish Marilyns), but have just 23 bagged in Scotland, so a long way to go there!
