The UK is home to some treacherous routes, but this one might be one of the most extreme. With an extreme gradient, no barriers and sharp turns, the route is a challenge for drivers.

The UK's wildest road was built by the Romans, reports The Mirror. Drivers are willing to take an hour detour to avoid travelling on it. The Hardknott Pass in the Lake District has an extreme gradient, no barriers and is notorious for breakdowns, accidents and being impassable in dangerous weather. One person on TripAdvisor who took the route said: "Certainly not for the faint hearted & not for a long bonnet either."

Some drive the route for its breath-taking views, but others would happily add time to their journey to avoid taking the dangerous road.

The Hardknott Pass is the most direct route from the central Lake District to West Cumbria but it is considered so difficult that drivers often decide to take an hour-long detour to avoid twisting up a single-track slalom on a mountainside.

It's 13 miles long and has been described as one of Britain's most outrageous roads.

One person who travelled along the dangerous road said: "Took this pass by mistake on the way to Muncaster Castle from Ambleside, it was the scariest drive I've ever done.

"Once on, you can't get off the road. There are sheer drops and the hairpin bends all added to the danger.

"If I had seen the warning sign I would never have driven up, it goes on for around 10 miles."

The person adds: "The views were breathtaking but I couldn't really enjoy them as I couldn't take my eyes off the road.

The road has a long and celebrated history - it was originally laid by the Romans around 110AD and led to the dramatic stronghold at the top of the pass known today as Hardknott Fort.

After the Romans left, the road lingered unloved and uncared for until the 1880s when a local hotelier association paid for some improvements.

Many reviews of the road reflect the opposing opinions of the pass.

One reviewer wrote: "Absolutely fantastic! I've been driving for years and am confident in my abilities so this proved an easy drive for me.

"Once over the peak, it's definitely worth a stop at the old fort to take in the views, which are just stunning."
