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.

Highest mountain in Northumberland national park, a decent path runs through to the summit as its a complete bog fest and there's not really any views as its a large plateau, but the views on the way back down are beautiful.

In the mid-13th century, Newton-by-the-Sea was part of the barony of Vesci, initially held by John Viscount for one knight's fee. Ownership passed through notable figures including Simon de Montfort and Edmund of Lancaster. By 1725, it became part of the Barony of Embleton and saw ownership by the Forster family, who built Newton Hall in the late 18th century for Joseph Forster. Low Newton, or Newton Seahouses, emerged in the early 19th century as a community for fishermen. The National Trust now manages some of these cottages, as well as the Coastguard Station, built around 1828. In the 19th century, Newton-by-the-Sea had around 250 residents. By 1895, it was a township of 1,211 acres with a population of 220. Today, the parish has about 135 dwellings, home to a mix of residents, holiday homeowners, and visitors. Many residents commute to nearby towns or Newcastle. The National Trust owns much of the coastal land and part of The Square at Low Newton.

Absolutely. Northumberland's landscape is shaped by fascinating geological features. The dramatic cliffs at Steel Rigg and Hadrian's Wall are a prime example, showcasing how ancient meltwater channels sculpted the land. St. Cuthbert's Cave is a unique rock formation, an overhanging outcrop of sandstone supported by an isolated pillar. The Drake Stone is a massive sandstone boulder, a glacial erratic deposited during the last Ice Age, adding to the region's geological intrigue.
The Northumberland Coast, designated as a National Landscape, features several stunning natural monuments. Holy Island (Lindisfarne) is a unique tidal island accessible via a causeway. Low Newton Beach offers beautiful sandy shores and coastal views. The Farne Islands, a short boat trip from Seahouses, are a significant natural monument known for their abundant wildlife.

The best time to visit Northumberland's natural monuments depends on your interests. For seabird colonies, particularly puffins, the Farne Islands are best visited between April and July.
