Aloha Matt ~ I am from Oregon, but now live in TN via Maui.
My friend Amara from Eugene moved to the Big Island and is part of the community at http://permaculture-hawaii.com/
I've wanted to visit for years now, but haven't made it.
I understand the ocean is a bit rough down mountain from their place, but there are natural hot pools to soak in.
On Kauai, another friend Tara from Oregon, is married to mushroom farmer Philly White. I hope to tour their facility some day. She teaches awesome yoga classes in Hanalei.
Have a wonderful time!
