Your journey into the depths of the Earth starts when we pick you up from your chosen location in Reykjavik. We then take you on a short drive through the scenic Icelandic backcountry towards Raufarhólshellir, one of the longest lava tunnels in Iceland.
This exquisite lava tube tunnel was formed during the Leitahraun eruption some 5200 years ago. Walk along paths formed by piping hot lava and discover colorful minerals, stalactites, and, in winter, icicles hanging over your head!
Raufarhólshellir Lava Cave is a whopping 0.87 mi (1.4 km) long, around 32 – 98 ft (10 – 30 m) wide, and 32 ft (10 m) high, so you’ll have plenty of space to walk around and take breathtaking photographs!
Next, we’ll grab lunch and head toward Þingvellir National Park. Spend your afternoon at Silfra Fissure in the heart of Thingvellir National Park. Silfra has been rated as one of the best freshwater snorkeling sites in the world.
Once on site, our guides will help you get into your dry suit and all other safety equipment, like goggles, breathing tubes, and fins. The guides are all PADI certified, so you can enjoy your snorkeling experience without any worries. Once everyone is suited up, we’ll enter the underwater world of Silfra.
Snorkeling between two tectonic plates should be at the top of everyone’s bucket list. The underwater visibility in Silfra stretches around 328 ft (100 m). While the crevasse doesn’t look like much on the outside, once you enter the depths it will take your breath away. The stunning ridges, crevasses, and unique rock formations will make you never want to return to land.
After your exhilarating snorkeling adventure, we’ll take you back to Reykjavik to have dinner and relax before the Northern Lights hunt begins! At around 8.30 p.m. we’ll pick you up again and drive you far away from the city lights.
The aurora is most visible away from light pollution and under the starry Arctic sky. While it’s almost impossible to predict exactly where the aurora will show up, our experienced guides know how to interpret the latest forecasts and will determine the best viewing areas on the spot. Your journey might take you to Thingvellir, Reykjanes, Hvalfjörður, or any other place far from artificial light.
The Northern Lights are only visible in places close to the Arctic Circle, making Iceland one of the best spots to see them. Once on site, look upward to see saturated hues of green, yellow, and, on rare occasions, blue, rose, and red dancing in the night sky.
We will pick you up and drop you off at your chosen location in Reykjavík. The pick-up time is 8 a.m. Picking everyone up can take up to 30 minutes, so your patience is greatly appreciated! For the Northern Lights adventure, we’ll pick you up again from your chosen location in Reykjavik at 9.30 p.m. (September, March, April) or at 8.30 p.m. (October – February).
Available pick-up points: Arctic Adventures’s pick-up list.
What to wear: thermal long underwear, warm and waterproof outdoor clothing, hiking boots, gloves, warm socks, a change of clothing (just in case). It’s good to have a tripod for your camera on the Northern Lights hunt.

Before and during activities on the multi-day tours consumption of alcohol is prohibited. If we suspect that a participant is intoxicated, we will prohibit them from joining the activity.

Yes, we do. Langjökull Ice Cave is a magical experience, the tour has no minimum age and is a wonderful option for the whole family. Whale Watching with our partner company Elding has been a favourite with families traveling with young children, these guys have a great success rate in seeing whales (upwards of 98% in the summertime).
Another option would be the Landmannalaugar Safari on this tour you get to explore parts of the Icelandic highlands and bathe in natural hot springs. Most of our jeep tours are also suitable for children over the age of 6 years old. If you would like a nice and relaxing experience we would also recommend the Golden Circle & Secret Lagoon tour.
Your safety is our number one priority! Keeping this in mind, Arctic Adventures reserves the right to adjust the itinerary and/or take different routes depending on conditions. Please read more information in our cancellation policy.
Yes, there is a specially trained and certified guide on each of our tours. The only exception to this is for our self-drive tours.

We’ve partnered with the Kolviður Fund in a new carbon offsetting program, which passengers can select to participate in at the time of booking.
The Kolviður Fund is the oldest, most respected carbon offsetting program in Iceland. With your support, one tree will be planted in special Kolviður forests in Iceland to carbon offset your tour with us.
Kolviður forests are strategically planted to absorb the maximum amount of CO2 and the forests are protected for a minimum of 60 years. During their lifetime the trees absorb carbon and store it in their root system, trunk, and branches. Trees also prevent soil erosion and maintain storage of carbon in the soil.
We provide you with a headlight and a helmet.
Like always in Iceland, it’s best to dress in layers. 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.
All relevant information for the tour can be found in our snorkelling handbook.
Yes, you can bring a camera, but we recommend to have a waterproof one if you want to have it in the water with you.
If you plan to drive and meet us on location, the meeting point is at the Silfra car park, in Thingvellir National Park.
GPS: 64°15’23.508″N 21°6’58.676″W
Note that the National Park charges a small parking fee of 500 ISK.
We kindly ask you to be at the Silfra car park 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 2990 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.
No. Unfortunately, glasses don’t create a seal between your face and the mask. We recommend wearing contact lenses instead.
You are not able to participate in the snorkelling tour if you are pregnant.
Yes, the tour is directed in English and therefore you need to be able to understand English to participate.
Some snorkelling 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.
You need to be more than 12 years old. Participants under the age of 18 must be accompanied by a parent or adult guardian booked on the same tour.
You need to know how to swim independently. Because of the dry suit sizes, there are height-weight limitations. The minimum height is 150 cm, and the minimum weight is 45 kg. The maximum height is 200 cm, and the maximum weight is 120 kg.

The minimum weight is:
- 45 kg (99 lbs)

Yes, you must be able to swim independently without a lifejacket, and you must be comfortable in the water.
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 to snorkel, 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.
We provide dry suits so that your body stays dry, and you will also wear undergarments to keep you warm. We use high-quality neoprene dry suits from Waterproof International and O´Three. But it is good to know that there is always a small risk that water can enter the dry suit. This is not dangerous but can feel a little cold, so 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 an undergarment and neoprene dry suit from Waterproof and 0’Three. We also provide a neoprene hood and neoprene wet gloves to protect your head and hands from the cold. You will also be given fins, mask and snorkel.
Our client to guide ratio is one guide for every 6 snorkelers.
The water temperature is 2-4 degrees C (35-37 degrees F) all year round. The water comes from the Langjökull glacier which keeps it nice and cool, and very refreshing!
We use high quality neoprene dry suits from Waterproof International and O´Three.
Yes, there are 2 toilet facilities at Silfra. However, we don’t recommend that you use them for changing, as it can result in long queues.
Sometimes fish venture into Silfra from Þingvallavatn lake, but they will quickly swim back, as they don’t like chilly glacier waters. However, there is plenty of colorful seaweed, including a bright green variety known as “troll hair”, which makes the fissure unlike anything on the surface.
The cave systems in Silfra can be up to 60 m deep. However, your dive in Silfra will be from about 7 to 12 m, and the maximum diving depth that is permitted is 18 m.
The Northern Lights are natural phenomena and we unfortunately cannot promise you will see them. Their appearance depends upon atmospheric and weather conditions.
For more information on the Northen Lights, please have a look at our Northern Lights information.
Unfortunately, there isn’t just one simple answer to this question.
There isn’t just one single setting for your camera that ensures great photos. But if you have manual options, you are probably best served with experimenting with various combinations of ISO, aperture, and exposure settings. As a rule of thumb, ISO setting between 800 and 3200, aperture between f/2.8 and f/5.6, and shutter speed at between 15 seconds and 30 seconds have proven effective.
A good thing to keep in mind, ISO setting between 800 and 3200, aperture between f/2.8 and f/5.6, and shutter speed between 15 seconds and 30 seconds have given great results.
Different combinations may give very different results. Higher ISO setting will allow you to capture faster exposures, but the downside to this might be for example grainier images.
If the shutter speed is above 15 seconds it will result in a slight star movement.
Wider angle lenses are usually more versatile in low light settings, but longer lenses give you different options for compositions. Make sure that you remove all lens filters, as they may distort images. You will probably get the best results with manual setting for infinite focal length
A refund is not available if the northern lights tour goes ahead and no northern lights are seen but we do offer you the chance to join a Northern Lights Minibus tour free of charge.
Please go to My Adventures to re-book your tour.
When Northern Lights tours are cancelled it’s usually due to unfavourable weather conditions.
In that case, your options will be to:
1. Reschedule for another day.
2. Find another tour to do and use the deposit for it.
3. Get fully refunded.
Like you might have heard, the northern lights are a pretty difficult thing to predict. You can check en.vedur.is to see the forecast and if the level is high and the skies are clear then it’s very likely that the tour is going. We do update our website’s tour departure sheet with the information at 17:00 pm the latest. If the tour is cancelled, you will receive an email from us.
If we think there is no chance at all of seeing the lights we will cancel the tour. We don’t want to bring you out and disappoint if there is no chance to see the lights.
Yes, the guide will take a photo of you with the northern lights behind you. These can be single or group photo’s and free of charge.
The Northern Lights season is said to be from late August until mid-April. However, if you want to increase your chances of seeing them, it is best to wait until the clear winter months of mid-September until March.
If luck and weather are on your side, then you will be able to see the Aurora Borealis above the inviting streets of Reykjavik. Whether you see the lights or not are dependant on two different factors. The first being the weather. If the sky is clear, no clouds, then you are halfway there to seeing the astonishing spectacle that is the Northern Lights (although light pollution can sometimes be a problem). Increased solar activity is the second half so, if these two merge together you may well be able to see the Northern Lights from Reykjavik.
