List Description

Marilyns are mountains or hills with 150 meters or more of prominence located in Britain, Ireland, and the Isle of Man. The name comes from a play on words, based on the first name of a famous American actress and the well-known "Munro" peak list of Scotland. This list only includes the Marilyns in Wales.


Peakbagging as we know it was invented in Britain, and there is a very long and rich long tradition of compiling hill lists.. The goal of this web site is to show a representative subset of some of the better-known lists from UK and Ireland in a global context, and not to be an exhaustive resource. There are countless other online destinations for information and ascent tracking in the British hills.

In compiling these lists, I used the Database of British and Irish Hills (DoBIH), Version 14.1, to supplement the data that had long been in the Peakbagger database. Thanks are also due to Alan Dawson, Chris Crocker, Rob Woodall, and Peter Stone for helpful comments and review of UK/Ireland data on this site.
