Personally I’d say cave diving. I was contemplating between that and free climbing soloing but I honestly rather fall to my death than drown in a claustrophobic, dark, cold, silted up cave.
Extreme Cave diving.
Edd Sorenson has some fantastic cave rescue / body recovery stories incase anyone’s interested. The dude is an absolute legend in the cave diving circles.
Cave diving is a good one. But also underwater cave diving, if that’s the right term. Seeing pictures of those those “don’t go beyond this point you will die” signs underwater is pretty dang spooky
I think “cave diving” is generally understood to refer to the underwater variety.
If you’re referring to general cave exploration, that would generally be called “spelunking”
Don’t read about https://en.m.wikipedia.org/wiki/Nutty_Putty_Cave then. Quite a way to go out, 28 hours headfirst into a crevice you can’t back out of. RIP
Russian Roulette.
Anvil firing
You get 2 anvils, stack them on top of each other, the bottom one upside down, pack some gunpowder between them, light it, run, and the top one shoots off into the air and eventually comes back down.
I’m sure it’s a blast (literally) but I’m not trying to looney tunes myself.
Three years ago, I broke my leg free climbing. It took two and a half years of physical therapy to get back to maybe 80% of what it used to be, and now I have a permanent metal plate. I was lucky it wasn’t any worse.
I don’t think I’ll ever free climb again, it’s just not worth it. However, I also would never do cave diving.
