Visit Booths at the station for great cheeses (Crumbly Lancashire, Black Bomber and their Red Leicester) and beers, wines etc. Visit Lakeland next door for household gadgets and solutions looking for a problem and a great cafe upstairs past the invisible pianist. Take a cruise or row a boat on Windermere. Go round to Grizedale for the zipwire and the Go Ape and bike hire, walking etc. Not sure if the steamboat museum has reopened but that used to be good; some lovely Edwardian steam yachts inside.
For unfit folk who fancy a nice walk, the circuit of Tarn Hows, just off the Ambleside to Coniston road is easy and beautiful. I sometimes take overseas business visitors there.
