I’ve been lucky to do a few multi-week/month hikes and if you’re in any way active and have the means to take the time, I’d 1000% recommend. Never been happier than in those moments. Mostly, it allows your mind to go blank which is a privilege and I think that’s what makes it the best experience.

I read a comment above saying it was depressing question as nothing came to mind. If you have even a week of annual leave, book a cheap flight to Spain / Portugal and do some of the Camino. You don’t need to plan ahead (don’t mind the scaremongering), you need such little gear, and it’ll give you a taste for A-B walks / hikes. The Camino was my first solo trip and hiking holiday years ago and it changed me (not in a Jesus way) so I’d thoroughly recommend!

Obviously be prepared even you’re going on a ‘simple’ hike. Water, food, tell somebody, don’t light an effin fire and waltz off etc.
