Peaceful Dragonfly, awesome place to stay! what a privilege! Admittedly outside the comfort zone of many--but if you're one of those, you probably haven't gotten as far as this review.
All the positive comments in previous guest reviews are accurate. The location is a simple drive from Hilo. Beyond Pahoa, the closer you get, the narrower the road, the more wondrous the trees and vines. Based on my experience, I recommend arriving in the morning to get oriented during daylight. While truly deep in the middle of nature, with only mesh screens separating you from the outside world, there's nothing rustic about the basic furnishings: comfortable bed, nightstand & lamp, small lanai, and simple, modern and clean bathroom with open-air shower. And just steps away, the meditation pavilion.
Maybe the most unforgettable part for me, the astonishing sounds of the jungle! Especially the amazing, nonstop, dusk-to-dawn chorus of coqui frogs (so near, yet you never see one!), providing a natural in-your-ear soundtrack, only broken by intermittent rain showers on the canvas roof. With sunrise, the nocturnal music is replaced by tropical birds and soothing ocean waves (only a short walk away). The first night, I had some misgivings about the frogs, but surrendered and probably never slept better, really! As a bonus, geckos are always nearby, and if you aren't already familiar with them, you will peacefully coexist and find them endearing. Only a few encounters with dragonflies, never less than cordial.
With only 3 days on the Big Island and so many places to explore, my time at KMEC was mostly limited to nighttime and early mornings. Otherwise, I would have enjoyed making use of the wonderful communal kitchen, a short ways up the trail by the cottages, as well as the spacious fruit orchard. Last but not least, the people I met briefly were all great, elevating the KMEC experience yet another notch.
