Summary
The Duddon Triangle Walk is a challenging mountain walk focusing on high-level crossings of the Ulpha Fells to the north of the Duddon Valley and the Dunnerdale Fells to the south of the valley. From the start at Ulpha Bridge, the walk heads in a clockwise direction, initially along the valley road following the River Duddon upstream to Whistling Green and continuing on road to Millbrow and Old Hall Farm. After leaving the road behind, a tough fell ascent is made to Whitfell. The Ulpha Fells are now the focus of an undulating walk, with Hesk Fell explored before the Duddon Valley to Eskdale road is crossed. Next in line come Great Worm Crag, Far Hill, White How, and Green Crag, before the gentle undulating walking is abruptly ended with a steep ascent needed to bag Harter Fell. At 653 metres, Harter Fell is the highest point on the walk. Next, the walk continues down into Dunnerdale Forest by way of Maiden Castle. The descent continues to the valley floor in the village of Seathwaite via Grassguards, Rowantree How, and Wallowbarrow Crag. If open, the Newfield Inn is a popular place to take refreshment. From Seathwaite, a tough climb to Caw is next on the agenda before crossing the Dunnerdale Fells on a gradual descent back to Ulpha Bridge.
