Aira Force to Glenridding
Above Ullswater
The longest day starts at Aira Force — the beck that falls into a wooded ravine above the lake — and stays high through the northern Eastern Fells all the way to Glenridding.
Aira Force drops 20 metres in a single fall into a gorge of ancient woodland above Ullswater. It's a good place to start a run that's going to ask something of you. From here you climb out of the trees and onto the open fell, with the lake laid out below and the first ridgeline ahead.
The day covers the northern and eastern high ground — Gowbarrow Fell first, then the ground above the lake's eastern shore, with Ullswater one way and the Helvellyn range forming the western horizon. It's 45 kilometres with nearly 2,000 metres of ascent. Long, steady, and the clearest possible introduction to what the Eastern Fells are.
