We visited two geothermal pools in Iceland. This tiny one was tucked into a hillside, and very cute, but also only big enough for a few people, and quite crowded. We didn't really have the chance to go in, even though the careful framing of these pictures doesn't show any bathing strangers. Trust me, they were there! I soaked my feet a tiny bit since I had twisted my ankle on the path walking down, which was nice, but Moss didn't even go that far. We'd read that The Secret Lagoon was better for swimming, and this turned out to be true. Hrunalaug is tiny and can't really handle all the traffic it gets. We were happy to have seen it, but would not suggest it as a main destination. Also, apparently tourists have been jerks and left trash behind or otherwise been disrespectful. We were careful to leave it as we found it, but were sad that others weren't.
