I feel like I need a break. Would be happy to spend £500 (maybe more). Somewhere I can get to within maybe 3hours of Glasgow (by public transport, happy to fly/train/bus/taxi). Probably with some nature? Would go on my own and want to mainly be on my own but not feel weird about it. Would love a Nordic cruise or something like that but maybe something a little more low key to start me off. Would like it to feel like an adventure. Any ideas??
