Lava Lookout is like nothing else. I chose it because it was cheap and I could still have my own bathroom. What I got was so much more (in a good way) than I ever imagined.
First the good stuff: a place off the grid like this draws people who are curious and open to the experience. If that does not describe you, please stay somewhere else. The beauty of this place is the starkness of the landscape in contrast to the warmth of the communal kitchen, where instant friends are made.
The bed in my room was very comfortable. The kitchen is well-stocked. Everything is as clean as it can be, given the surroundings (not germy, just dusty).
To set expectations, the lava around the property is uneven and sharp, so be careful if you plan to walk around. Spend a little time out at the lookout tower to get a sense of perspective. Take pictures of the vast night sky. Admire the little bit of crazy it takes to build something and live here. And be aware of the neighbors--some friendly, and some came out here for the solitude.
I traveled there solo, and easily and comfortably connected with my fellow travelers, most of whom were also solo.
Matt is the beating heart of this property. He is passionate about sustainability and the reclamation that went into everything you see there, and he is happy to talk about it if you ask.
If you go, be open. Appreciate the beauty in the imperfection. Trust the experience will bring you exactly what you need.
