You’ll hesitate for a moment, but then jump in anyway! The water between the two continental plates of Thingvellir National Park is around 4 degrees all year round, but with your thermal suit on you can relax with the current. In the crystal clear water you can sometimes see up to a hundred meters on this guided snorkelling trip. There’s undulating green algae and golden-yellow rocks to make this a completely alien underwater world.
Please note: If you suffer from heart or lung problems, have epilepsy, or if you are pregnant, this excursion is not suitable due to the cold water.
