The classic Lakeland arete over Red Tarn, with Ullswater and central-fell views

The line through Lake District, England, United Kingdom - waypoints, elevation and the day-by-day shape of the walk.
Late spring-autumn (a serious winter mountaineering route otherwise)
Wind and cloud make the arete dangerous; ice transforms it
Best late spring-autumn; in snow/ice it becomes a mountaineering climb - many winter accidents. Confirm.
A knife-edge rock arete to a broad summit, down Swirral Edge
Striding Edge is a narrow, airy grade-1 scramble with big drops; serious in wind/ice
Marked/waymarked route; navigation generally straightforward - carry a map and confirm locally
Suitable for reasonably fit hikers; not wheelchair accessible - confirm specifics
Very popular in summer
Avoid the edges via the Grisedale/greenside paths for a walkers’ route

Day route - none needed
