The experience looks pretty freaking awesome.
The slide sits in the middle of the jungle as part of a 25-mile irrigation system, hence the dangerous pipes you have to take to get to it. It was never intended for this type of use, and isn't maintained or regulated in any way.
"We need to discourage this as much as we can when people are saying things to appeal to a visitors that may want to do a reckless type of experience," Mufi Hannemann of Hawaii's Lodging and Tourism Association told Hawaii News Now last year. The official line is that the slide and structures like it are too dangerous for tourists to responsibly flock to, and that trespassing is against the law.
That's all well and good. Doing illegal things isn't something we'd ever endorse in this space of course. So next time you visit one of the country's prettiest states, don't skip the beaches, don't skip the waterfalls, but definitely don't forget that this thrilling, beautiful, possibly perilous, hidden wonder where a lot of people seem to have fun, exists either. Just think about it, really, really hard. Ponder the fact that hikers claim to leave beers at the gate for workers on their way out as they leave.
Make your travel decisions intelligently.
