"Excellent caving trip" | 5 stars By Fiona Macdonald 30/01/2018
Our guide Andrea was punctual, polite and friendly. A very informative and enjoyable trip
"I had a great time" | 5 stars By Wenjing Zheng 04/03/2018
The crew members are very friendly and lovely. The tour itself was more like a little adventure caving tour, and this is the kind of caving I love!
"Icelands Finest" | 5 stars By Lisa Reilly 08/03/2018
Definitely worth doing. Fine visual treats!
"Great trip" | 5 stars By John 10/03/2018
Our trip to the lava tube cave was well worth it. The trip was short, but not rushed and made for a great start to the day. Zaho our guide did a good job leading us through the caves. We would recommend it.
"Overall the tour was fab" | 5 stars By Hannah Vallance 01/03/2018
My only comment would be that the bus windows got lots of condensation on them so we couldn’t really enjoy the view on the way to the lava tunnel. Overall the tour was fab and I’d def recommend to a friend.
"Great tour!" | 3 stars By Caitriona Hartnett 06/03/2018
Great tour! Loved the caving but felt totally unprepared for crawling into a hole in the ground. Would have liked to be provided with clothing recommendations when we booked the tour. really enjoyed the golden circle tour! we booked 2 tours with your company - should have offered some sort of a discount for booking more than one tour.
"Both trips where very nice and the guide was great" | 5 stars By Nicole 10/03/2018
We make the tour together with the hirse riding tour. Both trips where very nice and the guide was great. The only problem was the connection between the tours which cost a lot of time.
"The Lava Tunnel tour was incredible" | 4 stars By Raven 22/03/2018
The Lava Tunnel tour was incredible and our tour guide was very knowledgeable. I’d definitely go on another tour with Arctic Adventures when I’m Iceland again!
"The part we saw was impressive" | 3 stars By Jennifer Lohmann 17/04/2018
Unfortunately, only a part of the cave was shown to us. The other part is not accessible in the "winter", the guide made us aware before the start. The tour through the cave lasted only 30 minutes. The part we saw was impressive.
"Great tour" | 5 stars By Cathal 31/01/2018
Great tour. Friendly guide. Ran like clockwork.
"The tour was great!" | 4 stars By Mário Canastro 11/05/2018
The tour was great! but there should be a little bit more explanation about the cave.
