This caving and snorkeling tour gives you an opportunity to experience Iceland from a new angle.
Pick up starts at 9:00 am from your Reykjavík accommodation. Please note, that the pick up can take up to 30 min.
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.
Because of the snorkeling there are some requirements:
Age limit: 16 – 65 years old.
Weight limit: 45-120 kg
Height limit: 150 cm +
Other requirements: Participants need to be comfortable in the water and be able to swim. You are unable to participate if you pregnant.
You can view the online medical form all snorkelers must fill out before going on the tour which is sent by email upon booking. If you mark YES on any of the questions in section 1 then you will not be able to participate. If you mark YES on any of the questions in section 2 you will need to get your Physician’s approval and signature on this approval form.
You will be wearing a snorkeling mask while in the water and you won’t be able to wear your glasses underneath. So unless you are bringing your own prescription mask we recommend that you acquire contact lenses for your snorkeling tour.
Photo or it didn’t happen?
We offer every snorkeler the opportunity of having their picture taken whilst enjoying the wonders of Silfra. You can purchase the photos from the tour on site for 3900 ISK. We accept cards and cash.
You need to know how to swim because you have to be comfortable with floating in water to be able to enjoy to the fullest.
Remember to bring: Warm and waterproof outdoor clothing, gloves, warm undergarments (fleece/wool), warm socks, a change of clothing (just in case).
What if I don’t own all of these clothing necessaries?
Don’t worry, you can always rent sturdy hiking shoes, waterproof jacket and pants in the booking process. We do not rent gear from location.
This is a combo tour and it is not an option to meet us on location.
Due to guide/customer ratio limitations and Þingvellir National Park regulations this tour sells out frequently, we recommend you book this tour well in advance.
We provide you with a headlight and a helmet.
You are in the cave for about 1-1,5 hours.
Like always in Iceland, it’s best to dress in layers. A warm layers closest to you preferably wool/thermal underwear, pants sweater and on top waterproof outdoor clothing. We also recommend that you wear good hiking boots and gloves. Jeans have proven to be a bad choice.
You can bring a camera, but if it is not waterproof it will get ruined. We recommend a waterproof camera. You can hire a waterproof digital camera or buy a waterproof disposable camera from us.
If you prefer to meet us on location you need to be at the Information Center at Þingvellir 15 minutes prior to your tour start. Make sure it’s the Information center NOT the Visitor Center.

Yes we offer the option, you basically have these two options regarding photos on tours:
For the first option, the snorkel guide has a camera and will take photos of Silfra and of the snorkelers, provided that everyone is comfortable. Safety if the most important thing. Customers can view the photos and if they like they can purchase them. We charge 3,900 ISK for all the photos from the tour. Customers can pay cash or card once they are back in Reykjavik, the guide will upload the photos to a dropbox account and send an invite to the customer.
The second option is to rent an underwater camera from us. We supply and prepare the camera for you so the you can take as many photos as you like. Then at the end of the tour we give you the SD card, included into the cost.
The cost is 4,990 ISK, but it must be booked at least one day before the tour so the guide knows to prepare the camera.
Unfortunately glasses don’t create a seal between your face and the mask. We recommend to wear contact lenses instead.
Basically, yes. All you need to do is book separate tours for the same time. You will spend most of the day together in the water. But you will have separate guides. You will both take the same route in Silfra and see the same places.
The general rule is if someone is greater than 2m tall or weighs over 140kg, then they would struggle to get into a suit. But it’s difficult to tell until someone tries on the suit because someone can weigh a lot because they have a lot of muscle. But this is the best rule of thumb we can give.
All our tours are undertaken on the responsibility of its participants. Arctic Adventures does not assume any responsibility for accidents that are caused by its customers or can be traced to their own actions. Participants have to sign a waiver before undertaking all trips stating that they realize that all outdoor activities carry an inherent risk.

“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.
“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.
