Old Man obvs – although it’s 600m of relatively steep walking – easiest route is probably up walna scar roar road and over/round dow crag. Coppermines valley up to leverswater or round from coppermine cottages to the bell and back to walna scar car park for something less demanding
but also walk along the ambleside road (nice fpath/bway) and go to yew tree barn(not to be confused with operation yew tree), eat cake drink coffee, meander up to yew tree tarn, very picturesque, pop up to tarn hows, reet bonny, bob down to monk coniston, more cake, then if you’re feeling brave head to brantwood for more cake, a bit of art/culture and steamer back to coniston (get on the gondola if you can) or walk back along shore. Black bull for a pint of blue bird.
Brantwood may also have theatre/music on in the evenings too.
Elterwater and langdale along the valley bottom for another easy walk. Or tilberthwaite to little langdale, refreshments available on both.
