Such a special piece of land. I imagine that you really do get the best sleep ever with the sound of those rapids always rushing. Inflatables or a kayak would be perfect for that river. The pool blessed by the mountain seems like the perfect place for a swim.
It looks like you have been in high gear for a while and still have plenty more work to do, but I know it is all going to turn out amazing. Can't wait to see everything when it is finished. That Airbnb is going to be THE spot, especially since you said you are the closest to the trailhead.
I have a whitewater rafting/kayaking/rescue background, and I immediately saw this potential. At highwater it is very kayakable, but not for the faint of heart. At normal water levels, the river is clear but shallow, so not boatable, but perhaps tubing would be a good idea. There is at least a 500 meter stretch that could be safely tubed, and for the most part there aren't any sharp objects, just a couple pieces of rebar embedded in concrete that need to be marked and padded/protected.
A future experiment is definitely going to involve buying an agricultural innertube of some kind, and seeing how difficult and/or dangerous it is to move through the rapids. The trailhead thing, the whitewater, I can imagine myself perhaps even marketing our place to my old adventure buddies back in Colorado, who are still doing things like ice climbing and rafting, etc. My extreme sports days are behind me, especially because of no insurance and Cambodian hospital standards.
That’s awesome! I’ve only been rafting a few times. We have the New and Gauley rivers here in WV, the latter being one of the most dangerous/exciting in the world at times. Sounds like you could turn your backyard into quite the little playground. It’s wise to only experiment to figure out how things can work back there, rather than putting yourself in danger over and over. I feel like marketing the place as an extreme Airbnb would be awesome for a lot of people. That’s an experience, not just a cheap place to stay.
