The North Coast 500 is a 516 mile scenic route around the north coast of Scotland, starting and ending at Inverness Castle. The route is also known as the NC500 and was launched in 2015, linking many features in the north Highlands of Scotland in one touring route.
The route has increased visitor numbers to parts of the north of Scotland, which has brought economic benefits to some areas. The increase in traffic has also led to more instances of bad and dangerous driving, as well as damage to the roads and concerns about the environmental impact.
Apparently the route was amended in 2022 with detours etc being removed.
