Keeping with the theme, ktsp and I went for a 3km hike (about 2 miles) up to a geothermal river, just half an hour's drive from Reykjavík. It was the hottest day on record in Iceland yesterday (76 F, 23 C), so we took advantage of it for an evening hike... and at the top, settled ourselves into a nice pool in the river, which was hotter than a hot tub (and flowing all around us).
It was absolutely lovely, and there was only one other couple up the river from us (hidden, since there are so many pools on this river), so we shed our suits and soaked naked for an hour or so. We are definitely going back there again, maybe when the air is a little cooler and the feeling of total immersion in a hot, flowing water will be all the more dramatic.
