We all had a great time! It was so amazing and our tour guide Stephano was amazing. He was responsible in showing us what to do and how to be safe but always lets us enjoy ourselves.

This caving and snorkeling tour gives you an opportunity to experience Iceland from a new angle.

After we pick you up from Reykjavík we start with the black part of the tour by exploring a lava tube cave close to Reykjavík. This adventure gives you a great insight of the volcanic activities that have formed Iceland. Depending on the season we go either to Leiðarendi Cave or Gjábakkahellir, both caves are typical lava tubes that display the characterizing features that are common for this type of caves.
After we finish the caving, you will have a chance to grab some lunch between the two activities.
We will drive to Þingvellir National Park where Silfra fissure is found. Here we get ready to explore the blue by putting on a dry suit and other snorkeling gear needed. Your guide leads you through the marvels of this crystal clear water wonderland that is considered to be one of the best freshwater snorkeling places in the world.

The minimum height/weight is 150cm&45 kg. The maximum height weight is 200cm&120 kg.
You need to know how to swim independently in order to enjoy this adventure.
All relevant information for the tour can be found in our snorkeling handbook.
When snorkelling in Iceland you will be wearing a dry suit, hood and gloves made of neoprene, along with fins, mask and snorkel. This equipment will make it not only possible, but also very enjoyable, to stay in the water despite the low temperature. It is a fantastic experience.
No, you don’t need any previous experience of snorkeling, but it is important that you can swim independently and that you are comfortable in the water.
Please wear or bring some long underwear, and some warm socks. Wool or fleece is the best material to wear. You will be wearing your long underwear and warm socks under the dry suit.
The idea behind the dry suit is that it should keep your body dry. We are using top quality dry suits from respected manufacturers. It can be good to know that where is always a small risk that water can enter the dry suit. This is not dangerous, but can feel a little cold. We recommend you bring a spare set of clothes and a towel, just in case. Kindly note that your hands and face will get wet, which is completely normal and not actually that cold.
We provide undergarment and neoprene dry suits from Waterproof and 0’Three. We also provide neoprene hood and neoprene wet gloves to protect your head and hands from the cold. You will also be given fins, mask and snorkel.
It takes about 30-40 minutes to slowly swim through the whole Silfra fissure. Once we reach the exit point you can choose if you want to get out of the water, or if you want to swim around a bit longer.
Our client to guide ratio is one guide for every 6 snorkelers.

“Black and Blue tour - a must do!”
We done the black and blue tour with Arctic Adventures (this is lava caving and snorkelling at the Silfra fissure). Our pick up was bang on time and our host, Linus (my spelling could be wrong), was excellent! We loved every second of the tour. Linus was funny, informative, and good at checking in with us a group as to what/how we wanted to do things. For example, you can take two different routes in the lava caves and Linus was very sensitive at making sure the whole group was happy to take the harder route. The snorkelling was incredible! The suits are incredible at keeping you warm and if you follow the advice from the instructors on how to keep your hands warm you’ll be totally fine! Other people had clearly ignored all the advice given to them… This was truly worth every penny and we got to see some increcible views. Miles of lava fields covered in snow is an incredible sight. 100% recommend this to anyone interested in geology or just doing things out of the ordinary.
Amazing experience, felt like we were in Mission Impossible
“Black & Blue - caving & snorkeling”
Had a terrific time on this tour – everything ran smoothly from hotel pick-up on. The snorkeling really is amazing – I’ve read some reviews of these type of adventures that make the drysuit sound more complicated than I experienced. The folks from Arctic Adventures made all of it simple. The lava cave was cool, too, and a good addition to the day since I had previously done a Golden Circle tour.
