The baths are man-made, but they’re heated to about 100° F with natural springs. There are two sulphur steam rooms and a smaller, hotter pool. The water is that now-familiar gorgeous, chalky blue, covered with a rolling layer of haze, and the view is all open sky and distant volcanos and lava-scape.
Afterwards, we checked into our hotel-on-the-moon, aka Hlid Hostel. We had a teensy private room with a teensy private bathroom, and everything felt clean, modern and very bright. But right outside our door, the world was rocky, flat and grey-scaled. I could have spent a full day just reading in the breakfast room, every once in awhile, glancing up at the lunar terrain.
