The Marilyns

A Marilyn is "a hill of any height with a drop of 150 metres (nearly 500 ft) or more on all sides".  So it is a hill which is relatively high compared to its surroundings.

A subMarilyn is a hill which just fails (by up to 10m) to qualify on the drop rule, i.e. drop of 140m to 149m on all sides.

The Marilyns are so-called by the list's compiler, Alan Dawson, after the more famous mountain list - the Munros.  Alan's original list is of mountains and hills in Scotland, England, Wales and the Isle of Man.  The same concept was applied to Ireland by E D "Clem" Clements

Anyone who has climbed 600 British Marilyns or more is eligible for entry into the Marilyn Hall of Fame.  Anybody wishing to make a claim should initially contact the Membership Secretary, Chris Watson, at

Change Register - registry of changes to the Marilyns list.

(Marilyns appear as Class=Ma on this website, and subMarilyns as Class=sMa).
