First....... holy yurt! It's amazing. I have never stayed in a yurt before and it was spectacular. The pictures do not do it justice. Much bigger than I expected , the decor is elegant and rustic. We cooked nightly, enjoyed hearing the rain in the evening. Seen the stars and slept well.
As everyone else has said, it is the road less traveled. You will be taking back roads to and from the yurt and they can be rough. 4x4 is the best option, not only for getting to the yurt but for some amazing attractions on the island (mauna kea/waipio valley ect)
Jim gave some very helpful tips on where to go and best ways to get there.
Enjoy your stay, the rest and relaxation and treat the place well.
Thank you to both Jim & Mercy.
