A Munro is a mountain in Scotland with a height over 3,000 ft (914.4 m). Munros are named after Sir Hugh Munro, 4th Baronet (1856–1919), who produced the first list of such hills, known as Munros Tables, in 1891. A Munro top is a summit that is not regarded as a separate mountain and which is over 3,000 feet. In the 2012 revision of the tables, published by the Scottish Mountaineering Club, there are 282 Munros and 227 further subsidiary tops. The best known Munro is Ben Nevis, the highest mountain in the British Isles.
The Munros of Scotland present challenging conditions to hikers, particularly in winter. Each year, people die on the mountains. Nevertheless, a popular practice amongst hillwalkers is "Munro bagging", the aim being to climb all of the listed Munros. As of 2009, more than 4,000 had reported completing their round. The first continuous round of the Munros was completed by Hamish Brown in 1974, whilst the current holder of the record for the fastest continuous round is Stephen Pyke who completed his 2010 round in just under 40 days.
- Ben Lomond, 3,196 ft (974 m), the most southerly of the Munros.
- Ben Hope in Sutherland, 3,041 feet (927 m), is the most northerly Munro.
- Ben Macdui, 4,295 ft (1,309 m) and Cairn Gorm, 4,085 ft (1,245 m) in the Cairngorms
- Buachaille Etive Mòr, 3,350 ft (1,021 m) at the entrance to Glencoe, one of the most photographed Munros
- Beinn Eighe, 3,310 ft (1,010 m), in Torridon
- Liathach, 3,461 ft (1,055 m), in Torridon
- Lochnagar, 3,789 ft (1,155 m) a mountain near the Royal Castle of Balmoral in the area of Glen Muick
- Schiehallion, 3,553 ft (1,083 m),a mountain often described as lying at the centre of Scotland, in Perth and Kinross
- Sgùrr nan Gillean, 3,163 ft (964 m); Sgùrr Alasdair, 3,251 ft (991 m) and the Inaccessible Pinnacle, 3,235 ft (986 m) in the Cuillin Hills on the Isle of Skye
Before the publication of Munros Tables in 1891, there was much uncertainty about the number of Scottish peaks over 3,000 feet. Estimates ranged from 31 (in M.J.B. Baddeley's guides) to 236 (listed in Robert Hall's third edition of The Highland Sportsman and Tourist, published in 1884). When the Scottish Mountaineering Club was formed in 1889, one of its aims was to remedy this by accurately documenting all of Scotland's mountains over 3,000 feet. Sir Hugh Munro, a founding member of the Club, took on the task using his own experience as a mountaineer, as well as detailed study of the Ordnance Survey Six-inch to the mile (1:10,560) and One-inch to the mile (1:63,360) maps.<ref>Bennet (ed.), The Munros: Scottish Mountaineering Club Hillwalkers' Guide, 1</ref>
Munro researched and produced a set of tables that were published in the Scottish Mountaineering Club Journal in September 1891. The tables listed 538 summits over 3,000 feet, 282 of which were regarded as "separate mountains" The term Munro applies to separate mountains, while the lesser summits are known as tops. Munro did not set any measure of topographic prominence by which a peak qualified as a separate mountain, so there has been much debate about how distinct two hills must be if they are to be counted as two separate Munros.
The Scottish Mountaineering Club has revised the tables, both in response to new height data on Ordnance Survey maps and to address the perceived inconsistency as to which peaks qualify for Munro status. In 1992, the publication of Alan Dawson's book Relative Hills of Britain, showed that three tops not already considered summits, had a prominence of more than 500 feet (152.4 m). Given this they would have qualified as Corbett summits had they been under 3,000 feet. In the 1997 tables these three tops, on Beinn Alligin, Beinn Eighe and Buachaille Etive Beag, gained full Munro summit status. Dawson's book also highlighted a number of significant tops with as much as 197 feet (60 m) of prominence which were not listed as Munro subsidiary tops. The 1997 tables promoted five of these to full Munro status.
Other classification schemes in Scotland, such as the Corbetts 2,500–3,000 ft (762–914 m) and Grahams 2,000–2,500 ft (610–762 m), require a peak to have a prominence of at least 500 feet (152 m) for inclusion. The Munros, however, lack a rigid set of criteria for inclusion, with many summits of lesser prominence listed, principally because their summits are hard to reach. The 1997 tables ironed out many anomalies, but despite it being the highest-profile hill list in UK, some still consider it not wholly satisfactory.
During May and July 2009 the Munro Society re-surveyed several mountains that are known to be close to the 3,000 ft figure to determine their height more accurately. On 10 September 2009 the society announced that the mountain Sgùrr nan Ceannaichean, south of Glen Carron, had a height of 2,997 feet (913.43 m).Therefore, the Scottish Mountaineering Club removed the Munro status of Sgùrr nan Ceannaichean and this mountain is now a Corbet<ref>http://www.munromagic.com/MountainInfo.cfm/284</ref>. In a Summer 2011 height survey by The Munro Society, Beinn a' Chlaidheimh was found to be 2,998 feet 8 inches (914 m) and thus short of the Munro mark. In September 2012, the Scottish Mountaineering Club demoted it from Munro to Corbett status.<ref>http://news.stv.tv/highlands-islands/189113-fisherfield-munro-demoted-to-corbett-status-after-coming-up-short-in-survey</ref>
As of September 2012, the Scottish Mountaineering Club lists 282 Munros and 227 further subsidiary tops.
Compared with some continental ranges, Scottish mountains might be modest in height, but walking and climbing in them can be treacherous because of their latitude and exposure to Atlantic and Arctic weather systems. Even in summer, conditions can be atrocious; thick fog, strong winds, driving rain and freezing summit temperatures are not unusual.
Winter ascents of some Munros are serious undertakings due to the unpredictable weather, the likelihood of ice and snow, and poor visibility. Some walkers are unprepared for extreme weather on the exposed tops and fatalities are recorded every year, often resulting from slips on wet rock or ice.
Some hillwalkers aim to climb every Munro, known as "Munro bagging". Munro-bagging is a form of peak bagging. A walker who has climbed all Munros is entitled to be called a Munroist.
By May 2013, more than 5,000 people had completed the Munros. The Scottish Mountaineering Club, who maintain a list of those Munroists who have reported completing the Munros, have attempted to popularise the archaic spelling of compleation.<ref>http://www.smc.org.uk/Munros/MunroistsCompleatists</ref>
Hugh Munro never completed his own list, missing out on Càrn an Fhidhleir and Càrn Cloich-mhuillin (downgraded to a "top" in 1981). Sir Hugh is said to have missed the Inaccessible Pinnacle of Sgùrr Dearg, on the Isle of Skye, which he never climbed. However the "In Pinn", as it is known colloquially within Scottish mountaineering, was only listed as a subsidiary top on his list (despite being several metres higher than Sgùrr Dearg, which was listed as the main top)<ref>http://www.hills-database.co.uk/downloads.html#munrotab</ref>.The first "compleationist" was to be the Reverend A. E. Robertson, in 1901, later minister at Braes of Rannoch from 1907. However, research has cast doubt on this claim, and it is not certain that he reached the summit of Ben Wyvis.<ref>Drummond, Peter; Ian Mitchell (1993). The First Munroist – the Reverend A E Robertson</ref>
Also it is known that Robertson did not climb the Inaccessible Peak of Sgùrr Dearg.<ref>http://www.walkingstories.com/original/innpinsummary.htm</ref>If Robertson is discounted, the first Munroist is Ronald Burn, who completed in 1923. Burn is also (indisputably) the first person to climb all the subsidiary "tops".
The person with the most rounds of Munros is Steven Fallon from Edinburgh, who has completed 13 rounds as of 2006 (15 rounds as of 2012).<ref>http://www.carnethy.com/press_2008/rep_steven_herald/steven_herald_2008.htm</ref> Chris Smith became the first Member of Parliament to complete the Munros when he reached the summit of Sgùrr nan Coireachan on 27 May 1989.<ref>http://www.smc.org.uk/Munros/MunroistsCompleatists.php?ID=719</ref> Ben Fleetwood is probably the youngest person to have completed a round. He climbed the final Munro of his round – Ben More – on 30 August 2011 at the age of 10 years and 3 months. The youngest compleationist to have done the round without the presence of a parent or a guardian is probably Andy Nisbet, who finished his round in 1972 aged 18 years and 1 month.<ref>http://www.ukhillwalking.com/news/item.php?id=63851</ref>
