Ben Nevis in the context of "Mount Paget"

The British Isles are an archipelago in the North Atlantic Ocean off the north-western coast of continental Europe, consisting of the islands of Great Britain, Ireland, the Isle of Man, the Inner and Outer Hebrides, the Northern Isles (Orkney and Shetland), and over six thousand smaller islands. They have a total area of 315,159 km (121,684 sq mi) and a combined population of almost 75 million, and include two sovereign states, the Republic of Ireland (which covers roughly five-sixths of Ireland) and the United Kingdom of Great Britain and Northern Ireland. The Channel Islands, off the north coast of France, are normally taken to be part of the British Isles, even though geographically they do not form part of the archipelago. Under the UK Interpretation Act 1978, the Channel Islands are clarified as forming part of the British Islands, not to be confused with the British Isles.

The oldest rocks are 2.7 billion years old and are found in Ireland, Wales and the north-west of Scotland. During the Silurian period, the north-western regions collided with the south-east, which had been part of a separate continental landmass. The topography of the islands is modest in scale by global standards. Ben Nevis, the highest mountain, rises to only 1,345 metres (4,413 ft), and Lough Neagh, which is notably larger than other lakes in the island group, covers 390 square kilometres (151 sq mi). The climate is temperate marine, with cool winters and warm summers. The North Atlantic drift brings significant moisture and raises temperatures 11 °C (20 °F) above the global average for the latitude. This led to a landscape that was long dominated by temperate rainforest, although human activity has since cleared the vast majority of forest cover. The region was re-inhabited after the last glacial period of Quaternary glaciation, by 12,000 BC, when Great Britain was still part of a peninsula of the European continent. Ireland was connected to Great Britain by the British-Irish Ice Sheet before 14,000 BC, and was not inhabited until after 8000 BC. Great Britain became an island by 7000 BC with the flooding of Doggerland.

The geography of Scotland is varied from rural lowlands to unspoilt uplands, and from large cities to sparsely inhabited islands. Located in Northern Europe, Scotland comprises the northern part of the island of Great Britain as well as 790 surrounding islands encompassing the major archipelagos of the Shetland Islands, Orkney Islands and the Inner and Outer Hebrides. The only land border is with England, which runs for 96 miles (154 kilometres) in a northeasterly direction from the Solway Firth in the west to the North Sea on the east coast. Separated by the North Channel, the island of Ireland lies 13 nautical miles (24 kilometres) from Mull of Kintyre on the Scottish mainland. Norway is located 190 nmi (350 km) northeast of Scotland across the North Sea. The Atlantic Ocean, which fringes the coastline of western and northern Scotland and its islands, influences the temperate, maritime climate of the country.

Scotland contains the majority of mountainous terrain in the UK. The topography of Scotland is distinguished by the Highland Boundary Fault which traverses the Scottish mainland from Helensburgh to Stonehaven. The faultline separates two distinctively different physiographic regions; namely the Highlands to the north and west and the Lowlands to the south and east. The more rugged Highland region contains the majority of Scotland's mountainous terrain, including the highest peak, Ben Nevis.

The Grampian Mountains (Scottish Gaelic: Am Monadh) is one of the three major mountain ranges in Scotland, that together occupy about half of Scotland. The other two ranges are the Northwest Highlands and the Southern Uplands. The Grampian range extends northeast to southwest between the Highland Boundary Fault and the Great Glen. The range includes many of the highest mountains in the British Isles, including Ben Nevis (whose peak contains the highest point in the British Isles at 1,345 m or 4,413 ft above sea level) and Ben Macdui (whose peak contains second-highest at 1,309 m or 4,295 ft).

A number of rivers and streams rise in the Grampians, including the Tay, Spey, Cowie Water, Burn of Muchalls, Burn of Pheppie, Burn of Elsick, Cairnie Burn, Don, Dee and Esk. The area is generally sparsely populated.

Glen Nevis (Scottish Gaelic: Gleann Nibheis) is a glen in Lochaber, Highland, Scotland, with Fort William at its foot. It is bordered to the south by the Mamore range, and to the north by the highest mountains in the British Isles: Ben Nevis, Càrn Mor Dearg, Aonach Mòr, and Aonach Beag. It is home to one of the three highest waterfalls in Scotland, Steall Falls, where the Allt Coire a'Mhail joins the Water of Nevis in the glen. Below the waterfall is a steeply walled and impressive gorge. The scenic beauty of the glen has led to its inclusion in the Ben Nevis and Glen Coe National Scenic Area, one of 40 such areas in Scotland. Several films have been shot in Glen Nevis, including some scenes from the Harry Potter movies, Highlander, Highlander III: The Sorcerer, Braveheart and Rob Roy.

A public road runs for 10 km up the Glen, becoming single track after 7 km. There is a hotel, Scottish Youth Hostels Association hostel, and campsite at the bottom of the glen, near Fort William, and a small hamlet further up at Achriabhach.

The Ben Nevis Race is a mountain race that takes place annually, from the foot of Ben Nevis (highest mountain in the British Isles) to the top, then back again. The course is 14 km long and includes around 1,340 metres of ascent. Up to six hundred people may compete in the event.
