Marilyn Munros vs Northing

Are your ready for the challenge of climbing the 202 Scottish Munro Marilyns or all of the 282 Scottish Munros? Munros are mountains that are at least 3000 feet (914m) high. Marilyns are at least 150m higher than the surrounding land. Track your progress on your own personal log and with an interactive map from OpenStreetMap. The Munro classification was created by Sir Hugh Munro in 1891 and the list is maintained by the Scottish Mountaineering Club. The Marilyn classification was created by Alan Dawson in his 1992 book The Relative Hills of Britain. The Marilyn Munros app is brought to you by the Relative Hills Society. © 2025 Doug Colton Walk descriptions © 2025 Relative Hills Society Base map and data from OpenStreetMap and OpenStreetMap Foundation © OpenStreetMap contributors All images are subject to copyright or are used through Creative Commons Licence
