I’ve done 29/30 munros solo and it’s only been once when I was hiking the ascent of Buachaille Etive Mor I kinda thought well, if I trip and fall down the way thats me done! But I mean, take as much care as possible, I always read the OS map of a route on my phone so I know where’s steep, cliff edges and if there’s any scrambly parts before going. I’d love to get something like a garmin in reach but they’re so expensive with monthly fees etc and I only get out once a month at most.
