The Blue Lagoon is a huge artificial lake of geothermal hot water just 30 minutes drive (or bus ride) from Iceland capital Reykjavik. The entrance fee is a bit high but worth it. Even though this place is very touristic and huge groups kept on entering, it is large enough not to feel too crowded and if you go to the back of the lake you get some peace and quite as most of the people just stay close to the entrance. Mud buckets are scattered around for facial masks and relaxing water massages are available. On the day of our visit a DJ was there with very loud music but he left just a few minutes after we arrived (16:00) leaving a quite and relaxing place.
