Waterfalls in paradise.

Heavy rainfall combined with some of the world's most rugged terrain has created some truly spectacular canyons in the world's most remote archipelago.​

Hundred, if not thousands, of canyoneering descents have been made in Hawaii as of 2025.

However, few canyoning routes in Hawaii have been published. There is significant pushback in some regions, especially Maui and Kauai, to anyone hiking off-trail, even legally. Having ropes and gear tends to create suspicions.

However, certain routes, on each island, are in public areas. Locals seem to mainly be concerned about damaging native species, bringing in invasive plant species, and creating overtourism in beautiful waterfalls. Respect these three rules, and you should have better luck on your canyoneering pursuits in The Aloha State.

As of 2025, I've only run a few canyons on Maui. I've been ogling some interesting-looking mega-waterfalls on the northeast coast of Molokai, as well as jungle ravines in the mega-jungles of the vast Big Island. Both locations have apparently seen extensive canyoneering efforts, yet there is currently almost no information on the internet.

Contacting local canyoneers via social media is the best way to get into these canyons. There are a few local canyoneers on each island, and, in my experience, some are quite friendly and welcoming (though others less so). Planning a trip can be difficult when you don't know where the canyons are, or if the locals are available, and realizing that flash-flooding can happen literally any day of the year in Hawaii (though it's more common in winter). For those willing to make the effort, Hawaii has some of the most fun and green canyons in the world. I have lots more planned in my future.
