The distance to travel all the way around Loch Ness is approximately 70 to 80 miles (112 to 128 kilometers), depending on the exact route and detours you take. For those driving or cycling, the journey follows the Loch Ness 360° Trail, which circles the entire perimeter of Scotland's most famous body of water. The north side of the loch follows the A82 road, which is the main artery between Inverness and Fort Augustus; this side is roughly 23 miles long and offers dramatic views and access to Urquhart Castle. The south side, following the B852 and B862, is much narrower, quieter, and more rugged, offering a "hidden" perspective of the water away from the main tourist traffic. For hikers, the Loch Ness 360° is a multi-day trek that connects the Great Glen Way on the north side with the South Loch Ness Trail. In 2026, the trail has become a premier destination for "slow travel," with many visitors taking 3 to 6 days to complete the circuit on foot. Along the way, you pass through charming villages like Dores, Drumnadrochit, and Foyers, where the famous "Falls of Foyers" provides a spectacular stop. The total elevation gain is significant, as the south side involves climbing into the hills for panoramic views.
