We absolutely loved our snorkeling experience. The water wasn’t even very cold with the dry suits on which was awesome. The whole family loved snorkeling and we were so glad we went! Our guide, Christian was amazing too!

If I could give this trip a negative star I would think about it. The equipment they used was old and beat. The tour guide was a bit surly. I didn’t think he had good accountability of the group the whole time sand could have probably used a little help.The experience was good. Very scenic, but I wish I had booked another operator. Let me give you one small example… bugs were terrible. Other tour operators let their guests use net hats to keep bugs off their faces. Our operator had his own net hat but he didn’t have any for the tour members to use and we were miserable. He may have tried hard but was a bit gruff. Not exactly Mr personality….it was kind of sad because I use Viator a frequently, usually with good results.
Poor customer service ...

Poor customer service The tour operator assumed I Had a medical condition and cancelled my dive after I assured her that I did not It was too early to text my US doctor for verification

Standing in the parking lot in the pouring rain wondering what the heck I was doing here!!!! Worth every moment, it was incredible! The visibility was amazing, and not as cold as I had thought! Its a must do tour!!!!
Just amazing

Huge shout out to Matt from Arctic Adventures for giving us the best tour we could hope for, such a great guy and a great tour guide and gave us all an experience we won't forget
Experience of a Lifetime!
Linda_M, Mar 2023
Crystal clear water with astounding view of the fissure and tectonic plates. Current moves you along, allowing you to focus on the views. Dimitri was an awesome guide and photographer. He not only has a great sense of humor, but was also calm and helpful me when I panicked. It is an effort to get in and out of the equipment. Just take your time and follow instructions.
Sensational experience. Highly recommend it.

Don’t miss this tour and this guide!

SIGGI was our guide. Knowledgeable, friendly,helpful. It was cold, icy. His warm enthusiasm was electric. If you don’t do this you are missing out. As a manager of a US tour company I recognize great service. He and the tour are great!
Christen_H, Jun 2021
The entire operation was beautifully orchestrated. The experience was a “once in a lifetime” gem. Our Guide, Byron was absolutely fantastic, he instilled confidence from the moment we met. The equipment was top notch, none of us were the least bit cold or uncomfortable. Five PLUS stars to Artic Adventures!
Not to be missed!

A wonderful experience! Our guide Nebo was great and we didn't get wet with the great suits. Super fun!
The Devil is in the details

Not until I landed in Iceland and read my three page voucher, that I realized my husband was over the weight limit. I wish this had been clearly stated. When I called to ask about his weight I was told I should have read the statement. I AGREE I just wish someone would have mentioned this @ the time of booking over the phone. The web sight does not lead with these requirements
A once in a lifetime experience

It was a new and different experience. Apollo, our guide was great. The whole team in fact was wonderful from helping get into and out of the suits. The cookies were wonderful as well!

After having the jitters prior to commencing the snorkelling, our guide made sure I was at the front and close to him at all times. After the initial shock of the cold water on our face and hands we gently proceeded through the silfra , the nerves passed and I can only describe this experience as unique in every way. Well worth it, no regrets what an experience.

My 2 guides were so awesome! The tour co. had some mix up with the pickup. They forgot to pick me up from my hostel, BUT they sent a personal cab! Feeling like a VIP! my cab driver was so awesome I feel like I had a personal tour guide on the way to/back from Pingvellir. 5 stars! Great customer serv
magistral moment

fabuleux, fantastique, très bien accompagné par un guide top, chocolat chaud et petits gâteaux en fin de seance.
À faire absolument
JeanLouis_B, Aug 2023
C’était top, c’est Alizé qui nous a guidé, elle est adorable et très pro. Bref une belle aventure que je recommande à tout les touristes. J’avais une appréhension avec les 2 degrés de l’eau mais avec la combi sèche on ne sent pas le froid, sauf sur la bouche qui est le seul contact avec l’eau.
Esperaba otra cosa

Lo contratamos como una experiencia d e grupo pequeño Cuando llegamos habíamos al menos 12-14 personas para tres monitores lo que implicó al menos hora y media para colocarnos trajes y prepararnos a todos Pero aún peor fue que al llegar al lugar d e inmersión había una cola formada por los otros grupos al menos seis grupos más y esperamos casi otra hora para la inmersión Finalmente dos horas y media de preparación para media hora d e inmersión Además otros monitores eran más comunicativos pero el nuestro no nos sacó fotos prácticamente ni nos ayudó demasiado cuando tuvimos algún problema durante el paseo Sinceramente es la primera vez que me decepciona tanto una experiencia viator Salvo la inmersión que es espectacular en sí misma lo demás no está a la altura
