As we were planning our trip, everyone said, "Make sure you spend time at Mytvatn." So we did. We heard about the fabulous hiking and walking around there, interesting geologic lava flows, hot springs and boiling mud pots, the geothermal power plant, and on and on. The maps show a "Yellowstone-Park-like" filigree of roads and trails to explore. That was the demo. Reality was on a much smaller scale.
I mention Yellowstone park because I am very familiar with it. Also, because the map looks similar ... big lake, rivers, geyser areas, mountains ... similar when you look at a map. I neglected to factor in scale. Yellowstone park is the size of Iceland. Mytvan is the size of a small county in my native Washington. It's all there: the springs; the trails; the mountains; the power plant; and so on but we budgeted one too many days to see it. Also, we had the worst of all our hotels here. It wasn't bad on an absolute scale, but in the league table of hotels we stayed at, it was at the bottom.

These photos were taken in August 2007 mostly with a Nikon D200.
