The Scottish Highlands have a seemingly endless list of unforgettable experiences, and people travel from different parts of the world to experience them. Many travelers visit Inverness before visiting the famous Loch Ness, among the other lochs stretching across Scotland.
Unlike many lakes worldwide, Loch Ness stretches for about 23 miles and measures only about 1.7 miles across, making it a very thin and long lake. From a bird's-eye view, Loch Ness, Loch Lochy, and Loch Linnhe make a straight line through the Scottish Highlands.
This line is not a coincidence but rather the result of millions of years of geological activity, adding to Scotland's mystery and allure.
In Scotland, the word "loch" refers to lakes and sea inlets, derived from the Scottish and Irish Gaelic language.

The Great Glen Fault Is Scotland's Mysterious Straight Line
When looking at a map of Scotland, a straight line runs north to south, starting at the northern harbor town of Inverness and stretching all the way down to Loch Linnhe, which empties into the Atlantic Ocean. This eye-catching geological feature is no coincidence; rather, it has defined the landscape of the Scottish highlands for millions of years.
Geologists call this line the Great Glen Fault, a strike-slip fault that formed roughly 400 million years ago due to plate tectonic activity. Scientists believe that the Great Glen fault formed when two plates scraped against each other during the age of dinosaurs, forming the mountains and hills that define this area's landscape. However, some aspects of the Great Glen fault remain a mystery, such as how far it has moved.
According to the Geological Society of London, "Like other major fault zones worldwide, the Great Glen has a long history of reactivation. Although it is known that the northwest and southeast sides of the fault are moving in opposite directions, there is currently no agreement on how far they have moved."

Although it is known that the north west and south east sides of the fault are moving in opposite directions, there is currently no agreement on how far they have moved." - The Geological Society of London
Today, the area remains largely geologically inactive. However, scientists occasionally record small earthquakes and tremors throughout the region. The valleys of this fault have since filled with water, forming the legendary lake Loch Ness, Loch Lochy, and the scenic Lake Loch Linnhe to the south.
This fault also serves as the boundary between the Grampian Mountains to the south and the Northwest Highlands to the north of the fault, mountain ranges known for offering a long list of day-hike opportunities. Examples of strike-slip faults are found worldwide, including the San Andreas Fault in California and the Anatolian Fault in Turkey.
However, these faults are far more geologically active than the Great Glen Fault, and significant earthquakes regularly occur there.

The Great Glen Fault Defines The Region
Close
Not only has the Great Glen Fault defined the Scottish Highlands physically and geographically, but it has also long defined the region's politics and economy. This naturally occurring line has long served as a traveling route for people since people first entered this region, and to this day, the A82 highway and Caledonian Canal run along the Great Glen fault.
The Great Glen fault has long served as a vitally important border in Scotland, separating the Western Highlands from the rest of Britain. For example, the Great Glen fault was an important boundary during the Jacobite risings in the 17th and 18th centuries. This bloody movement pushed for the restoration of the Scottish House of Stuart.
Today, the lochs that run along the Great Glen Fault serve as a hub for tourism in the region, with millions of tourists visiting these scenic and beautiful natural wonders every year. Loch Ness and the legend of the Loch Ness monster particularly attract curious travelers, who can book a glass-bottom boat tour of Loch Ness, hoping to catch a glimpse of Nessie swimming through the cold depths of this ancient lake.
However, Loch Ness is known for more than its monster. The ruins of Urquhart Castle, first built in the 13th century, sit on the western banks of Loch Ness, allowing visitors to glimpse what remains of medieval Scotland. North of Loch Ness sits the town of Inverness, which many call the capital of the Scottish Highlands.
Inverness offers travelers a wide array of delicious food options and exciting adventures. Tourists often visit Inverness Castle, which towers above the landscape of this quaint highland town. Visitors can also pay their respects at the Culloden battlefield, just miles from downtown Inverness. This is the site of the Battle of Culloden, in which British soldiers massacred as many as 2,000 Jacobite fighters during the Jacobite rising of 1745.
For anglers, Inverness serves as an ideal location to flyfish for salmon, a fish that has long served as a staple food for people in the Scottish Highlands.
