Icelandic nature boasts a series of never-ending wonders that simply can’t be missed! Silfra is located in a UNESCO World Heritage Site and more than merits its spot as one of the top dive locations in the world.
Silfra’s unique natural history, incredible location in Thingvellir, and unbelievable electric-blue waters make it the best snorkeling location in the world.
Where else can you swim between continents and see the epic landscape created by two moving tectonic plates? Combine that with the chance to explore ancient lava tube caves formed thousands of years ago by volcanic eruptions. Now you have a life-changing tour that guarantees an amazing experience!

Your tour will begin when you’re picked up from your selected location in Reykjavik. The volcanic landscape of Iceland is rich in lava tube caves that have formed as a result of eruptions over the millennia. We start out at Raufarholshellir volcanic cave just a short drive from Reykjavik.
The ancient lava flows have created incredible formations and unique patterns in the rock. In winter, you can also see the glistening naturally-formed ice sculptures that contrast with the dark stalagmites, stalactites, and other formations.
The 1360-m (4500-ft) long Raufarholshellir is Iceland's third-largest lava tube.
Hiking in this otherworldly lava tunnel is not considered difficult. However, be aware that in some places you might have to get down on hands and knees or duck your head. But don’t worry, there will be plenty of open spaces to take outstanding pictures too!
After the cave exploration, you’ll have time to grab lunch before moving onto the second part of your adventure. Prepare for snorkeling in Iceland’s cherished natural wonder!

For part two of this trip, we go to Thingvellir National park for some snorkeling action in the Silfra Fissure. This rift between the North American and Eurasian tectonic plates is famous for the clearest water on Earth. It’s a must-do for anyone seeking a different kind of snorkeling or diving tour. The visibility in Silfra reaches beyond 100 meters, and there is plenty to admire down there!
Float weightlessly above the rift. Find yourself surrounded by vivid shades of blue, interrupted by the sun rays as they slice through the underwater canyon. Marvel at the bronze walls of the fracture and touch the green algae as you swim.
The meltwaters originate at Langjökull Glacier and are filtered over decades by porous lava rocks. There’s no harm in taking a sip of the pristine glacial water while you’re there!
Before we head back to Reykjavik, we’ll take a quick moment to enjoy the spectacular view of Thingvellir along with some hot chocolate and cookies.
Pick-up will begin at 8 a.m. from your hotel or nearby meeting point in Reykjavik. Please be aware that picking everyone up can take up to 30 minutes. Your patience is greatly appreciated. You can find a list of all available pick-up points in Rey...)

Please note that the National Park charges a small parking fee of 500 ISK.
We kindly ask you to be at the Silfra car park at least 15 minutes prior to your tour starts,
Our guides normally have an underwater camera and usually, take photos during the tour. If you are interested in photos please let your guide know before you go into the water.
You can then buy the photos from your guide at the end of the tour, for a price of 3 900 ISK, which includes all the photos from that day. Kindly note that photos cannot be guaranteed. Our customer’s safety and wellbeing is our first priority, and therefore the guide will focus on snorkelers as a priority when in the water and will be taking photos when everyone is comfortable.
Unfortunately, you cannot wear glasses as the glasses don’t create a seal between your face and the mask. We recommend wearing contact lenses instead.
You are not allowed to participate in our snorkeling tour if you are pregnant as it can put your baby in high risk.
Yes, you must be able to understand English to a participant. The tour is directed in English.
You need to be more than 12 years old ( guardian’s approval needed for minors under 18) and you need to know how to swim independently.

Some snorkeling tours match with a dive tour, and then you will be in the same area at the same time. You will, however, be in separate groups with separate guides, and won’t be in the water exactly at the same time.
Yes, you must be able to swim independently without a lifejacket and feel comfortable in the water to take part in the tour.
It is a magical experience. When snorkeling 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 as well very enjoyable to stay in the water despite the cold temperature. Tripadvisor recently rated Snorkeling at Silfra as one of the Top 5 travel experiences in the world.
No, you do not need any previous experience to snorkel, however, it is important that you can swim independently and feel comfortable in the water.
We highly recommend long underwear and some warm socks. Wool or fleece is the best material to wear. You’ll be wearing the clothing under the dry suit.
We provide you with high-quality neoprene dry suit so that your body stays dry. There is always a small risk that water can enter the dry suit, that is not dangerous but you can feel a little cold, therefore, we recommend you to bring an extra spare set of clothes and a towel, just in case. Note that your hands and face will get wet, which is completely normal.
You will be provided with high-quality neoprene dry suit from Waterproof International and O’Three. As well as neoprene hood and gloves to protect your head and hands from the cold. You’ll also be given fins, mask, and snorkel.

Yes, there are two toilet facilities at Silfra.
Occasionally fish venture into Silfra from Þingvallavatn lake, but they will quickly swim back as they don’t like the cold glacier water. However, there is a lot of colorful seaweed including a bright green variety known as ‘’troll hair’’, which makes the fissure unlike anything on the surface.
Silfra can be up to 60m deep. However, when you’re diving in Silfra than you will go about 7 to 12m deep, and the maximum diving depth that is permitted is 18m.
Yes, we will provide you with a headlight and a helmet.
The Icelandic weather is very unpredictable therefore we highly recommend to dress in layers. Warm layers closest to you preferably wool/thermal underwear, pants sweater and on top waterproof outdoor clothing. It is also suitable to wear good hiking shoes and gloves. Jeans have proven to be a bad choice.

My husband and I did the Black and Blue trip firstly doing the caving which was informative and well guided. In the afternoon we did the snorkeling at Silfra, now this was one of the reasons we came to Iceland and were not disappointed. The weather was cold and windy and we were concerned that we would freeze but I have to say I was at my warmest while being outside when I was in that dry suit! Entertaining getting in it but all the same warm. Your hands do get cold but as advised by the instructor just keep them still and it's not that bad. Highly recommend.

The Black and Blue Tour was incredible! Starting off at the cave and going underground is something I’ve never done before and it was so cool. Then we went snorkeling which was truly remarkable. Being between the tectonic plates is something you can only experience here so it is really a once in a lifetime experience. Steve was our snorkeling instructor and was amazing. He answered all questions and remembered each of our names in our small group and was very knowledgeable about snorkeling and the area. The hot chocolate and cookies at the end was a sweet treat! I would recommend this to everyone I know that visits Iceland because it was so incredible.
