Cold Fell, at 621 m (2,037 ft), is a rather remote and boggy mountain top just south of Tindale Tarn. It makes for a good hiking outing from Hallbankgate, taking in the Brunwath Viewpoint. Being a UK designated Nuttall and Marilyn, it is a popular hiking point offering expansive views over Cumbria and the Lake District.

Cawfields Quarry is a former quarry located directly on Hadrian's Wall near Haltwhistle. Constructed in the early 20th century, the quarry cut through the Roman wall, exposing the underlying dolerite rock of the Whin Sill. This geological formation formed a natural defensive line upon which the Romans built their wall. Following the quarry's closure, the site has been redeveloped into a peaceful recreation area with a picturesque lake, picnic areas, and walking trails. The area offers direct access to Milecastle 42.

As of September 27th 2023 we are shocked and desperately saddened to learn that the famous Sycamore Gap tree at Hadrian's Wall has been felled overnight in what appears to be a wanton act of vandalism. We know just how much this iconic tree is loved locally, nationally and by everyone who has visited. It has been an iconic and important feature of the Northumberland landscape for nearly 300 years. https://www.bbc.co.uk/news/uk-england-tyne-66947040

This is a beautiful spot in an old quarry and the start for many a good walk. There are nice views of the quarry and nearby parts of Hadrians Wall. It is also a perfect place for picnics and has good facilities too.
