Like an irritable old codger fed up with the neighbor kids trampling his flower bed, the Earth has posted "No Trespassing" signs all over Iceland. "Nothing says Stay Away better than a hissing pool of mud," reasons the Earth. "And what's more, I'll make it stink of sulfur!" Makes sense, but what do we humans do? We turn it into a tourist attraction! Man, are we annoying.
While we enjoyed our visit to the Blue Lagoon, we did have a few complaints. It was too expensive, too crowded and although the landscape of black lava was striking, it could have benefited from more variety. Iceland was apparently listening to us and taking notes, because we found all our complaints improved upon at the "Blue Lagoon of the North": the Jarðböðin Nature Baths.
The Viti Crater is part of the Krafla volcano range just to the northeast of Mývatn. Viti is Icelandic for "Hell", and we experienced some unreal weather on the morning we chose to visit.
Just outside the hot spring haven of Hveragerði is the Hellisheiði Geothermal Power Station. If you want to visit, don't worry about accidentally driving past without spotting it. This is the world's largest geothermal plant, spouting giant columns of steam high into the atmosphere, and it's unmistakable.
Precariously situated in the middle of an active geothermal area southeast of Reykjavík, Hveragerði makes for an easy excursion from the capital. During our visit, we explored hot springs, ate an geothermally-cooked egg and treated our feet to a therapeutic mud bath.
On either side of Reykholt are two remarkable water-related sights. Measured by the volume of water produced, Deildartunguhver is the largest hot spring in Europe. And Hraunfoss, or the "Lava Field Waterfall", is precisely as strange as its name implies.
The Haukadalur Valley, found along the Mid-Atlantic Ridge just northeast of Þingvellir, is an especially restless area of geothermal activity. Along with other bubbling pools of rotten-smelling sulfur, it's here that you can find Geysir. This is the original -- the geyser which lends its name to all others.
Close to the Perlan Building, and directly underneath the path of roaring planes landing at the nearby Reykjavík airport, is the Nauthólsvík Geothermal Beach, one of the city's favorite hangouts.
