On my way to find the Haughton Green bothy, I stumbled upon the stunning Cawfields Quarry, a former limestone quarry within the Northumberland National Park.

In addition to its calming atmosphere Cawfields Quarry has historical significance.

The site contains remnants of Hadrian's Wall, a UNESCO World Heritage Site built by the Romans in the 2nd century AD to fortify their northern frontier in Britain. Hadrian's Wall runs along the northern edge of the quarry, and visitors can explore the remains of the wall and the nearby milecastle.

Whilst swimming is not permitted at the quarry, there are some smart new washrooms and toilets here, making it a useful stop when I come to hike the Pennine way.
