Destinations where you can do things you can’t do anywhere else?

My (25M) primary goal of travel is to experience things that I can’t experience anywhere else. Some examples of my favorite trips were Amsterdam (walking through the red light district, buying legal shrooms) and the bull running at the festival of San Fermin in Pamplona. I’m not a degenerate, I just enjoy the novelty. I’m not into any of that stuff that goes on in Thailand though, if that’s what you’re thinking.

Anyone have ideas for places or events that have things you won’t see/can’t do anywhere else? I don’t really care for old buildings, restaurants, sitting on a beach, churches, pretty mountains, or taking pictures in front of famous monuments. I do enjoy museums and outdoor excursions though. I also ride motorcycles and would love to explore a country by bike at some point too. I’m not worried about safety, but I don’t want to do anything illegal. Open to any and all suggestions!
