Runnable start to finish — nothing here forces you to walk.
A flat, scenic 17.5 km loop linking the shores of Buttermere and Crummock Water, with barely 80 m of climbing. An easy valley run ringed by some of the steepest fells in the western Lakes.
Two of the prettiest lakes in the district on one near level circuit, including the short rock tunnel cut through the crag on the Buttermere shore.
The route
This 17.5 km loop strings together the two lakes of the Buttermere valley on good, low paths. With only around 80 m of ascent it is one of the gentlest long runs in the area, which makes it a fine recovery day or a first attempt at the distance. There are no fells to climb here, so the effort comes purely from the kilometres.
Starting from Buttermere village you follow the Buttermere lakeshore first, a flat and mostly firm path beneath the towering slopes of Fleetwith Pike and High Stile. Partway round you pass through the short rock tunnel, hewn through a crag so the shoreline path could continue, which always raises a smile mid run.
The two lakes
A brief link past the village takes you onto the second half around Crummock Water, the larger of the pair. The western shore here is quieter and a little rougher underfoot, with the bulk of Mellbreak rising straight from the water. Views back to the head of the valley, with Haystacks and the Buttermere fells stacked behind, are some of the best lake level scenery in Lakeland.
Why it works
It is honest, low level running with huge mountain surroundings and none of the navigation or exposure of the high routes nearby. Footing is good enough for steady running throughout, with a few stony and rooty sections to keep you paying attention. Pair it with a swim on a warm day, or use it as a relaxed leg stretch between bigger outings. There is parking and a tea room in the village, so you are never far from a brew at either end. The valley feels remote despite the easy going, and in autumn the bracken on the surrounding slopes turns deep copper, making this one of the most photogenic low runs anywhere in Lakeland.

A few rocky and root crossed sections near the shoreline can be slippery when wet, and the rock tunnel on the Buttermere shore is low and dark. Lake paths can flood after heavy rain.
Leave No Trace
- Leave nothing but footprints, take nothing but memories.
- Please respect the countryside and all its inhabitants.
- Dogs on leads near livestock, and around ground-nesting birds from March to July.
- Gates as you find them — open or closed, leave it that way for the farmer and the next runner.
- Take it all home — wrappers, peel, tissue, the lot. It doesn't count as biodegradable if you can still see it.
- Stick to the path where the ground either side is wet, planted, or nesting habitat.
Common questions
- Most runners complete Buttermere and Crummock Water Circuit in 1 hour 55 minutes to 2 hours 35 minutes, depending on pace and conditions.
