This is a list of mountains in Britain and Ireland by height and by prominence. Height and prominence are the most important metrics for the classifications of mountains by the UIAA; with isolation a distant third criterion. The list is sourced from the Database of British and Irish Hills ("DoBIH") for peaks that meet the consensus height threshold for a mountain, namely 600 metres (1,969 ft); the list also rules out peaks with a prominence below 30 metres (98 ft) and thus, the list is therefore precisely a list of the 2,756 Simms in the British Isles (as at October 2022). Many classifications of mountains in the British Isles consider a prominence between 30–150 metres (98–492 ft) as being a "top", and not a mountain; however, using the 30 metres (98 ft) prominence threshold gives the broadest possible list of mountains. For a ranking of mountains with a higher prominence threshold use: * List of Marilyns in the British Isles, for ranking by height and by prominence, of peaks with prominence over 150 metres (492 ft); or * List of P600 mountains in the British Isles, for ranking by height and by prominence, of peaks with prominence over 600 metres (1,969 ft) As of 31 December 2021, 7,098 people had climbed all 282 Scottish Munros, as of April 2020 eleven people had climbed all 1556 Marilyns of Great Britain, while as of October 2022 only five people had climbed all the 2532 Simms of Great Britain, Ken Whyte (Cruachan Beag 21/09/2010), Iain Thow (Cut Hill 07/06/2015), Michael Earnshaw (Cruach Fhiarach 16/07/2019), Rob Woodall (Sgurr Dhonuill West Top 28/06/2021) and Anne Bunn (Torr Ceum na Caillich, 24/09/2022). The first three have also climbed the Irish Simms, so including all the Simms of the British Isles. (en)
