Until 2023 there was a tree in a national park near me that was 65m tall, and you could climb to the top because there were rebar climbing pins in the tree. Not a ladder, as such, but just steel pins sticking out from the trunk about 2 feet apart, spiralling up the tree at an 80 degree angle. There was no safety net, no safety line, no harness, no gates. It was not 'closed' during major storms, it was just assumed nobody would climb in one. You could just drive up, and start climbing in thongs and a bintang singlet during a thunderstorm if you wanted to.

Sadly this era came to an end in 2033 when they restricted the climb to just 30m.

Nobody has ever died falling from it.
