Scotland has approximately 221 hills as of 2018 Scotland is the most mountainous country in the United Kingdom. The area north and west of the Highland Boundary Fault is known as the Highlands, and contains the country's main mountain ranges. Scotland's mountain ranges, in a rough north to south direction, are: The Highlands & Islands, The Hills of the Central Lowlands, the Southern Uplands. The zone includes Britain's highest peaks, especially Ben Nevis, standing at 4,411 ft, with several similar peaks in the Cairngorms. in Skye, photograph showing and taken by Dr Simon Ross Valentine Some of the most spectacular mountains occur in the northwest highlands, especially on Skye, the largest island off the coast. On the mainland nearby lie some great ranges based on the Torridonian sandstone, a Precambrian rock which overlies yet older rocks such as the Lewisian gneiss. Some of the highest peaks, such as Beinn Eighe, are crowned by white quartzite, which gives those peaks a distinctive appearance. The trend continues to the north, with larger caps of the white rock at Foinaven and Arkle. Some of the quartzite contains fossilised worm burrows. It is known as pipe rock and is around 500 million years old. The formation continues to the north with gigantic peaks such as An Teallach near Ullapool, and Stac Pollaidh in Sutherland. The Torridonian rocks continue south to Applecross opposite Skye, where similar massive mountains occur. The Black Cuillin are mainly composed ofbasalt and gabbro; the latter is a very rough rock which makes for superb grip for mountaineers. It is from the dark colour of the gabbro that the Black Cuillin receive their name. The summits of the Cuillin are bare rock, jagged in outline and with steep cliffs and deep cut corries and gullies.
There are many notable individual peaks, and many exceed 1,000 metres in height, so qualifying as Munros. Ben Nevis exceeds 1,300 metres. To the south, Glen Coe has many notable mountains, such as Buachaille Etive Mòr and Bidean nam Bian, both of which are Munros. There is also a famous ridge walk, the Aonach Eagach, on the opposite side of the glen. The ridge is one of the most popular scrambles in the entire country; it is a craggy arête with few escape routes. The Grampians extend from southwest to northeast between the Highland Boundary Fault and the Great Glen, occupying almost half of the land area of Scotland and including the Cairngorms and the Lochaber hills. The range includes many of the highest mountains in the British Isles, including Ben Nevis and Ben Macdui, the two highest. The Cairngorm Plateau is the highest, coldest and snowiest plateau in the British Isles.
Hills of the Central Lowlands
The southern and eastern parts of Scotland are usually referred to as the Scottish Lowlands, but these areas also have significant ranges of hills, although these are lower than the Highland mountains. Because they are much closer to towns and cities, they are more popular for hill walking and rambling than the more distant mountains of the northern Highlands.
Sidlaw Hills, north of Dundee but south east of the Highland Boundary Fault
In addition to the main ranges, there are numerous individual hills in the Lowlands, often volcanic in origin. Many are known by the Scots word Law, meaning hill
Southern Uplands
The Southern Uplands form a continuous belt of hills across southern Scotland from Galloway to the Borders. The Uplands are divided into several local ranges. The heartland of the Galloway hills lies to the north of Loch Trool, and many excellent walks start from the extensive car park by Bruce's Stone. There are three ridges which run northwards from the Loch Trool/Loch Dee/Clatteringshaws area: The Awful Hand on the west, The Rhinns of Kells to the east, and the Dungeon hills in between.

Lowther Hills
Moffat Hills
Pentland Hills

Lammermuir Hills
Cheviot Hills, which lie mostly in England and form part of the border between the two countries
Scottish peaks are categorised in the following hill lists. A peak may qualify for inclusion in more than one list.
The Munros are the most significant hills in Scotland over 3,000 feet, according to original compiler Sir Hugh Munro. The list was first drawn up in 1891, and is modified from time to time by the Scottish Mountaineering Club. It currently comprises 282 peaks, following the demotion of Sgurr nan Ceannaichean in September 2009 and of Beinn a' Chlaidheimh in 2012.
The Corbetts are hills in Scotland between 2,500 and 3,000 feet, with a relative height of at least 500 feet. The list is maintained by the SMC. There are currently 221 hills.
The Grahams are hills in Scotland between 2,000 and 2,500 feet, with a relative height of at least 150 metres. The list of hills fitting these criteria was first published by Alan Dawson in The Relative Hills of Britain. under the provisional name Elsies. They were later named Grahams after the late Fiona Torbet who had compiled a similar list around the same time. The SMC incorporated the list into Munro's Tables in 1997 but Dawson continues to maintain the list. There were originally 224 Grahams, but the current total stands at 221 after Corwharn, Ben Aslak and Ladylea Hill were surveyed as falling short of 609.6 m
The Donalds are hills in the Scottish Lowlands over 2,000 feet. The list was originally compiled by Percy Donald, and is maintained by the SMC. It comprises 89 summits and 51 subsidiary tops, giving a total of 140 hills.
The Marilyns are hills in the British Isles that have a relative height of at least 150 m, regardless of distance, absolute height or merit. The list was compiled and is maintained by Alan Dawson. There are 1,216 Scottish Marilyns, see List of Marilyns in Scotland.
