Kirkjugólf sounds a bit like "Kirk, you golf?" but rather than being an invitation to hit the back nine, the name in fact means "church floor." The honeycomb-shaped basalt rock comes from a long-ago volcanic eruption. People thought it looked the kind of surface found inside churches, and not remnants of a lava flow - thus the name. Like many other natural wonders in Iceland, this one is just kind of sitting out in a field, with very little signage or other indications that it exists. I got there by following a narrow, worn path in the grass through a pasture, which I reached by crossing over a fence behind the information board in Kirkjubæjarklaustur. If I hadn't known about this in advance, courtesy of the tour books, I never would have found out about it in town.
