Gotta be my first real wilderness trip, in the Hammastunturi wilderness area here in Finland. I was going through some shit at the time and after losing my job due to covid it was a really low point in my life. I don't exactly remember how I got the idea, but basically I scraped together whatever second hand gear I could get, packed a weeks worth of food, took train+bus north and just set off. No real plan, I didn't even have a proper map of the area. In retrospect it was really dumb, but luckily nothing truly bad happened. Don't get me wrong, it wasn't exactly easy with the shitty gear (my backpack literally had a gaping hole in it) and me barely knowing how to start a fire or set up my tent. Not to mention way too many mosquitoes!! But mentally it was great and really helped me to get into better headspace. And it got me into hiking and backpacking and I've been hooked ever since.
