Snorkeling the plates - I had an excellent time with James the pick up from my hotel stop was easy and the instructions on site for snorkeling were clear and the instructors did a great job of securing my dry suit. It was an unforgettable memory.

Once in a lifetime experience - A once in a lifetime experience would highly recommend it. Our driver James was amazing and so lovely. For the Snorkelling I was in Konrads group and he made me feel so comfortably especially since i’ve never been snorkelling before. The weather wasn’t the best but the guides were outstanding with making sure we were all safe and calm when going into the water and after. If you’re going to Iceland i’d most definitely book this,, the best experience!

Once in a life time - do it! - This was one of the best things we did in Iceland. The pick-up was smooth, small group, no drama. Our guide was calm and reassuring and you felt very safe the whole time. Yes, it’s freezing. You know that going in. But once you’re floating there, it’s just surreal. The water clarity is unreal. It genuinely feels like you’re flying. Floating between tectonic plates is not something you do every day and it really did feel like a once-in-a-lifetime experience. Expensive, yes. Worth it, absolutely.

What a great experience!... - What a great experience! Snorkeling between the tectonic plates was amazing. The guides were amazing, my wife was a little nervous, but they assured her it would be great. We went in February and thankfully it was warm outside, about 34 Fahrenheit. The coldest part was waiting to change into the dry suit. Once in the water it was comfortable in the dry suit.

Fun Time! - It was great snorkeling! If you are uncomfortable with tight clothes the dry suit is very tight around the neck and hands. I was worried about being cold but in the end, only my hands were cold.

An amazing experience and the water temperature was bearable. - I had an amazing experience that I am so glad I did. I was nervous about the water temperature beforehand, but the dry suits we were provided did a decent job of keeping us warm enough (it was cold, but not unbearable, and certainly not as bad as I thought it would be). Also, the dry suit made me incredibly buoyant, so I barely had to swim at all (you don't have to be a strong swimmer to enjoy this experience). The clear water allowed for amazing sights of all the impressive geological features below. The water is so clean and clear of any pollutants that we were told its completely safe to drink (I didn't try it, personally, but others said it was very refreshing). Overall, I thoroughly recommend this experience.

Checked off my bucket list - Doing this in the winter was another level of adventure. They supply the warm onesie, the dry suit and all the rest of the gear. Come dressed in your good thermals and bring a few pairs of warm socks. Getting the gear on can be uncomfortable but the reward is absolutely amazing. An unforgettable experience!
