This was a great experience, truly once in a lifetime. The water was so clear and the view was amazing. Chico and his colleague were awesome guides and super fun; they made sure we were well equipped and safe. The drysuits are a bit uncomfortable to wear but you can’t feel the cold water at all. Overall this is a must do in Iceland, 10/10 would recommend! The only thing that would be better than this would be scuba diving-which they also provide :)

Fantastic tour! Vanessa was an excellent guide and the pictures she took were the perfect way for us to remember such an amazing experience! I was prepared to be pretty miserably cold the whole time but I can say it really was not as bad as I thought it would be - I was comfortable in the dry suit. Also, you float very easily so do not need to worry about sinking or having to exert yourself swimming the entire length. Very cool experience!

Our guide Anais was incredible. The team did an excellent job of explaining things. The dry suits kept us dry and cozy. The views in the water were just spectacular. My only feedback would be to consider investing in a few suits for short people with hips. My suit was clearly built for a bigger man based on the length and size. I know they are expensive, so just something to consider. Overall had an amazing time!!

We had an amazing experience with Troll expeditions, Veronica our guide was friendly, funny and knowledgeable making the activity extremely enjoyable! We would definitely recommend this activity, the water was so clear and we were very happy that the dry suits kept us dry and warm in the cold temperatures!

A great experience. Super competent guides with a lot of good humor. There was information about the process and the area. A lot of attention was paid to the well-being and asked again and again. I would repeat the offer with this provider at any time. Highly Recommended.
