Thingvellir National Park

This UNESCO World Heritage Site is one of the most important destinations in the entire of Iceland, combining spectacular natural scenery, rich history, and geological significance. It is the site of Althingi, Iceland’s original parliament that was first convened in 930 AD, making it one of the oldest democratic institutions in existence. This coupled with its unique geological location, which straddles the continents of both Europe and North America, ensures that Thingvellir is one of the most alluring destinations in the entire world. It is an area that was crafted by the molten lavas of Iceland’s capricious volcanos, meaning that its soil is fertile, and it has some mesmerizing rock formations. Thingvellir is an unforgettable place that all visitors to Iceland should cross off their bucket lists.


The Silfra Fissure

A sapphire jewel, situated in the heart of Thingvellir, this magnificent diving site is frequently rated as one of the world’s best. Silfra is essentially a crack between two tectonic plates, meaning that you will literally be swimming between America and Europe. This coupled with underwater visibility of more than 100 meters, thanks to the icy glacial waters that come from one of Europe’s largest glaciers, makes it a profound experience that will inspire awe and wonder in equal measure. The opportunity to explore this turquoise wonderland crammed with underwater treasures should not be missed. Our experienced guides will provide you with all the equipment that you need and take you into this otherworldly blue world, dotted with emerald plants and spectacular rock formations.


The Secret Lagoon

One of the oldest swimming pools in Iceland, this invigorating pool of nutrient-rich waters is set in a jaw-dropping volcanic landscape that will take your breath away. Its geothermal waters are heated to around 40 degrees, making it ideal for bathing. It is the perfect place to experience one of nature’s finest spas and allowing the volcanic waters to lap over you is one of the finest experiences that Iceland has to offer. Winter visitors may be lucky enough to see the dancing, flickering lights of the Aurora playing overhead: a truly magnificent sensation, which is enhanced by the milky volcanic waters of the lagoon. No trip to Iceland would be complete without a bath in one of its many hot springs, the Secret Lagoon is among the best of them, making it a must-visit during your stay.

There are a few different ways you can book our trips. First of all, you can book almost all our trips right here on our website. There is a booking window on each tour page and we do recommend that you book and pay for your trip there, preferably in good time as we keep our groups small and some tours tend to sell out.

If the trip you would like to book is not bookable online, you can call our office directly, the phone number is +354 562 7000. Another way is to send us an e-mail with an inquiry through our contact form. What we need to have is your name, how many people are in your party, where you are staying, a way of contacting you either an e-mail or a phone number and what tour you are trying to book.

How do I pay for a tour with Arctic Adventures?
  1. You can pay through the internet, through our website. This is by far the easiest, safest and fastest way to reserve and pay for your adventure. If you choose this way then you will receive a voucher as a confirmation via e-mail which you will need to bring with you for your trip.
  2. You can pay via phone, the phone number is +354 562 7000.Please Note: However you pay, you will always get a voucher: REMEMBER TO PRINT IT OUT AND BRING IT ALONG OR MAKE SURE THAT YOU CAN SHOW IT ON YOUR ELECTRONIC DEVICE!
When is a booking for a tour with Arctic Adventures confirmed?

A booking is confirmed when you receive a confirmation email. If you think you have made a booking and have not received an email confirmation, please send us an e-mail with an inquiry through our contact form, and we will figure this out together.

What currency do you accept?

We process all payments in Icelandic króna (ISK). Prices in your currency might vary slightly depending on the conversion rate set by your card issuer.

Arctic Adventures is not responsible for currency changes between different currencies.

Is there a participation minimum?

Most of our tours have no minimum but there is a minimum of 2 people for a few of our trips. If you are interested in a trip that has a minimum of 2 persons and are travelling solo we can take down your information and contact you if more people book the trip.

Do you do private departures for any of your tours?

Yes, we arrange private departures on request. Most of the tours we offer can be arranged as a private tour. If you wish to have a private tour arranged you can contact us through email custom@adventures.is.

Please have a look at all of our private tours.

Do you have a waiting list for tours?

We, unfortunately, don’t have a waiting list for our tours but feel free to check the availability sheet on our website as all updates will automatically be made to the sheet listed in each tour‘s description. We also offer a lot of different adventure tours around Iceland so chances are that we will have a similar version of the tour that you were originally looking for.

How does the refunding procedures work when we cancel a tour?

If we cancel a tour you have booked with us you will receive a 100% refund. The refund process is different depending on the way you booked the tour.

If you booked the tour on our website we will start the refund as soon as we know you will not be rescheduling and you will receive a separate email with the confirmation once the refund has been processed. It can then take a few days for the amount to show back up on your bank account once the refund has been processed and we, therefore, ask you to be patient.

If you booked the tour through a booking agent you will need to contact them to receive the refund. We will confirm with them that the tour was cancelled and the refund process will start on their end. Arctic Adventures only receives a payment when the tour has finished, this means that your payment is still with the booking agent and therefore, the refund will be processed by them.

If you pay with you card via email or phone you will need to contact us the same way again to be refunded.

I want to book but a member of my group has not reached the minimum age, what can I do?

We can not accommodate a person that has not reached the age limit on the tour. We put great value towards the safety of our customers and the minimum age policy falls under this. The minimum age requirement is decided by our operational managers and is dependent on each activity and it‘s difficulty ratings and can, therefore, vary between tours. We ask you to try to understand that this is based on safety procedures and we can therefore unfortunately not make any exceptions to this rule.

Arctic Adventures is a part of VAKINN which is the official quality and environmental system within Icelandic tourism. VAKINN provides validation of insurance, safety and regulatory requirements which supports increased quality and safety within the tourism industry.

The tour I am trying to book has less seats available than I need, what can I do?

Our website shows the correct number of available seats left so we can unfortunately not accommodate you and your group if the number of your group extends the number of available seats left. It is not possible to squeeze additional participants onto the departure as we have really strict policy measures as to how many participants are assigned to each guide on our tour departures. This is of course done with our customers safety in mind, so we do hope that you understand.

Which payment methods does Arctic Adventures accept?

We accept Visa, MasterCard, American Express, Discover, Diners Club for all countries.

In addition, we offer various local payment methods in many other countries such as UnionPay and JCB (Japan Credit Bureau).

The safety briefing will also cover potentially foreseeable scenarios that may arise and explain how participants should react in such circumstances.
