Blue Lagoon, Iceland

[Bede735]

I went there a few years ago during March and visited an outdoor pool. I think there are around 7 of them in Reykjavík. It seemed bizarre swimming outdoors when there were snowflakes fallen on you, but the steam coming off the water protected you.
I didn't shower naked. There may have been a sign saying that but as the signage was in Icelandic I wouldn't have understood it.
