Hands down one of my favorite experiences!! Our guide, Veli, was more than welcoming and friendly. He helped us suit up, explained some of the history of the fissure and national park, made sure all people in our party were comfortable and safe. The fissure itself was just amazing. The most beautiful and purest water I've swam in, and not as cold as you'd think with a layer of clothing & wet suit pieces. Make sure you take a sip, too!! My only 'downfall' was I personally would've loved to be able to dive down and get more than a 'birds eye view' of the fissure. Those wet suits make it perfectly impossible to sink below the surface! I was a part of the first group of the day at 8am and I highly recommend. We had no other groups/crowd to swim around, and we were able to take our time and take in the views leisurely.

The snorkeling tour was really awesome and Avelino was a great guide. The hot chocolate after the snorkeling was also nice. Would highly reccomend it

Great time. Freezing, but not as cold as I thought I was going to be. Wilmar was an awesome guide. Would recommend to anyone!

The experience was unique and our guide Konrad was excellent. The uniform we wore was 100% waterproof so we didn't feel cold at all. Only the gloves had an issue, so our hands were a little bit freezing but all good!!!

We had the best time snorkeling with Diogo! The staff at Dive.is is awesome - from the office managers who helped us navigate to the location, to the dive leaders who kept us laughing the ENTIRE TIME, this whole experience was magical. Diogo was the best - he was super informative and his instructions were great. He is an incredible guide! Thank you all so much - Diogo's Gorls miss you already!

What a cool experience! We had Quim as our guide and had a great time. Water is crystal clear, you can see all the way to the bottom. The dry suits do a pretty good job at keeping you warm!

An amazing experience with beautiful underwater images. A snorkeling tour I would strongly recommend when coming to Iceland!

Lisa was fantastic and we got lots of nice photos! Very chilly in the water but the team are so efficient in getting all the gear on and off and in providing hot chocolate and biscuits!! What an experience :)

Snorkeling in the icy but so clear waters was a once in a lifetime experience. Asier was an excellent guide. Be mentally prepared for the uncomfortable choking dry suits but once you are floating in the water the feeling is totally incredible

Snorkeling the Silfra is an amazing experience not to be missed! We had a beautiful sunny day and had a great guide, Konrad! He was patient and very informative. The Viking baptism at the end was a perfect way to end our tour.

This was the coolest this to do - weird sensation snorkelling in a dry suit! Lisa was an amazing guide, she was funny and made sure we were all having a great time. She was super patient with me having to swap suits before we started. The hot cocoa at the end was the best way to finish off!

An incredible experience!!! Lisa was very helpful and made us feel super relaxed😀😀😀It was such a fun time 😀 Thank you!!!

Asier was a great and funny guide. Very helpful and looking after our group, would recommend to everone who likes to snorkel

It was amazing experience. We could see so many meters below the water level. Papi was our guide, he was very cool and very instructive.

Unforgettable experience with the Dive.IS crew! Diogo was an amazing guide and walked us through each part of the process very clearly! 10/10 would recommend and ask for Diogo! Underwater views were stunning 🤩

Incredible experience, Asier was a wonderful and friendly guide. He took many photos of us and as we had only a small group was able to chat with us all.

The experience was unique although a little bit freezing (fortunately only for the hands) Our guide Conrad was amazing and very helpful.

I did the tour as a local meet on my way to doing my own Golden Circle. All of the liability and medical release were sent ahead of time and could be done online. Meeting place instructions were very clear and it was extremely well organized. Our guide Quim from Lleida was amazing and personable. I would highly highly recommend this trip to anyone who is capable is swimming, although all you had to do was float around.

Alex was a terrific guide for the snorkel tour. The activity was just as described. Customer service was good throughout the process. Alex was fun, funny and knowledgeable. She had a good emphasis on safety and made sure everyone in the group was enjoying the experience.

Amazing trip and guide!! Asier showed the group an unforgettable experience and would highly recommend anyone going!!
