the blue lagoon is a definite must. I would have given this 5 stars except for the fact that this was actually 2 tours back to back, so instead I actually had to go back to Rekjavik after the lagoon and then get on another tour for the geysir express tour. It would have been better if it was just continuous, less time wasted travelling back and forth.

The guide was great! Answered all my questions and made the whole experience enjoyable and fun. An underwater camera is a must. The water is cold but you wear an insulation suit under a dry suite so its actually not that bad even though the water is only 4 degrees C. This was a great experience, I've never been snorkeling before and this was an excellent first time.

Great! We werent able to see the lights the first night so I was allowed to go a second night for free and we eventually saw the lights. Definitely take a camera that is capable of capturing low light images, regular cameras and cell phones won't capture the images

I didn't get to see any puffins but we did get to see dolphins and Minke whales! It was extremely cold with the sea winds so definitely wear warm clothes
