Off-grid living in the jungle but still conveniently located. My tiny cabin is fifteen minutes from Hilo and the airport and is centrally located to Volcano National Park (25 minutes), Puna and Red Road (35 minutes) and Hilo and the Hamakua Coast.
This house is an example of sustainable entirely off-grid living in Hawaii. It has a 500 watt solar system and batteries for power, water catchment for water, a lava rock outdoor shower with hot water (propane, yes, there is some fossil fuel use even here), and a rainwater-fed outhouse with flushing toilet for doing your business. It's a one-room cabin on three acres about 15 minutes from Hilo airport and centrally located to all that East Hawaii has to offer, from the Kapoho warm ponds to the active Kilauea volcano to the Hamakua Coast.
I'm biased, but this tiny house makes me very happy just hanging out. I visit regularly (I live mostly in Santa Barbara) and I work on writing projects or just putz around the place landscaping or doing home improvement projects. It rains regularly, a delicious warm rain, which keeps it lush and full of life.
The kitchen is fully equipped with a two-burner stove that works very well, a medium-sized fridge and a large sink. It's a lot of fun to cook in! There's also a little grill for use on the lanai if you want to go native and cook some local ahi in ti leaves on the grill (a local specialty).
There are no visible neighbors and it's pretty jungly so if you like walking around in your birthday suit in nature, or just to the lava rock outside shower, this is the place for you.
This is a one-room cabin (16x16), with covered deck (lanai, 8x16) that's a good size for two people. There's also a futon for guests to sleep over.
If you're interested in experiencing pristine Hawaii this is a great place to do it. My place offers the convenience of being only five minutes from Keaau, and only two minutes from a 7-Eleven, the J. Hara convenience store with the best fried chicken ever, and fifteen minutes from Hilo, but also out in the country with only one neighbor who isn't even visible or audible. Birds abound, as well as geckos and coqui frogs. There are some mosquitoes but use the smoke rings available in the cabin and you'll be good to go.
It rains almost every day at least for a little, which is how it stays so green, usually in short heavy showers that give way to sunny skies before too long. It's always warm, though, so it's not an inconvenient rain like it is in colder climates. 70s to low 80s is the temperature range all year 'round.
