Oh it was hard to leave! I had 3 nights on the lava and loved it. From the bedroom/lanai (the yellow building) the glow (at night) and steam (daytime) from the current sea entry and rift is visible about 4 miles away. Fantastic.
I hadn't thought about navigating the lava between the main building and the bedroom until I arrived. You do have to be careful, but there is good motion-detecting lighting and torches provided.
The whole place is spotless and really interesting /quirky (in a good way) - I loved the car seat sofa. Kitchen water is from those big blue bottles - I wondered if I'd be able to switch to a new bottle, but it was easier than I expected.
When I was staying the composting toilet was out of action so I had to use a portaloo next door, but that wasn't a big issue.
The property is right on the track towards the current lava viewing point which makes it super-easy to walk, hire a bike, or get a shuttle which cuts 2 miles off each way ($30 return). You can hear people coming back until about 10pm, but they are generally a happy crowd!
