Thornthwaite Force is a modest but attractive waterfall on Haweswater Beck, set within a narrow wooded ravine about 100 yards east of Naddle Bridge near Burnbanks. Here, the outflow from Haweswater Reservoir tumbles over rocky ledges in a rush of white water before continuing north-east through the Lowther Valley. Beyond Burnbanks and Bampton Grange, Haweswater Beck eventually joins the River Lowther, which carries its waters towards the River Eamont and the Eden. Surrounded by mature trees and rich riverside vegetation, the falls provide a peaceful and picturesque feature beside the Coast to Coast route.

Naddle Beck rises in the hills and forests above the eastern shore of Haweswater Reservoir. Flowing north-east between the Harper Hills and Highfield Crag, it curves around Naddle Farm before turning towards Naddle Bridge. Here, the beck joins Haweswater Beck, adding its waters to the river that drains the reservoir and continues through the Lowther Valley.

Naddle Old Bridge is an 18th-century single-arch stone bridge and a Grade II listed structure on the edge of Burnbanks. Although now bypassed by a modern road bridge, it remains an attractive feature of the valley. Just beyond the bridge, Naddle Beck joins Haweswater Beck, creating a confluence that can be seen on the eastern side of the crossing.

Haweswater Beck carries water from Haweswater Reservoir through the wooded valley below Burnbanks. The Coast to Coast path follows its banks from Naddle Bridge to beyond Park Bridge, where the river turns north towards Bampton Grange. After a journey of about a mile and a half, its waters join the River Lowther, which continues through the Eden Valley.

A short distance beyond Thornthwaite Force, Haweswater Beck passes beneath Park Bridge, a small stone crossing that carries the access track to Thornthwaite Hall. Framed by trees and fast-flowing water, the bridge marks a pleasant point along this quiet stretch of the Coast to Coast route.

Between Park Bridge and Rawhead, Haweswater Beck makes a sharp turn to the north as it continues towards Bampton Grange. At this point, a simple wooden fence spans the river, creating an unusual feature beside the water. The bend offers an attractive view of the beck as it leaves the wooded valley below Burnbanks.
