The Blue Lagoon (or Bláa Lónið in Icelandic) is one of Iceland's more famous attractions. The facility is state-of-the-art, and the setting is picturesque. However, add in hordes of flabby tourists yelling things like "I don't need to sun myself here, I get plenty of that on the Jersey shore...", think about all the gunk you can't see under the water, and realize that the whole lagoon is really just the outlet pool of a nearby geothermal plant, and the place loses some of the appeal. Still, it's worth a visit... but perhaps the middle of winter, or the first minutes of the morning would be the best time.
