Some of the buses in the Lake District are open topped, hop on and hop off, free with a oldies bus pass*, mostly half hourly from early to late seven days a week, with much much nicer scenery than going round a big town or city and excellent for getting to plenty of proper pubs. I used them over four days a week ago between Kendal, Windermere, Bowness, Ambleside, Grasmere, Keswick, Longthwaite and Seatoller.
* And even without a oldies bus pass my ten journeys capped at £2 would be less than a day on an open topped hop on and hop off bus round Bath.
Buses. Use them or lose them.
