The tour was fun but difficult due to the limited daylight in January! Additionally, trying to figure out which bus to board was a nightmare. The tour guide Christina originally told us we were not on her tour bus and directed us away quite rudely. We had to go back again and check her list ourselves! We arrived at the first stop in thingvellir national park and it was pitch black. We didn't get to see anything as we arrived there quite early and only had a 30 minute stop. The rest of the golden circle tour was okay but I would highly recommend hiring a car and doing it yourself. Snowmobiling on the other hand was absolutely amazing! Super well organised and the views were insane. We had a good 1 hour on the snowmobile which I think was perfect. Anymore than that and my fingers would have dropped off! Overall I think the tour was great. Best option would be to drive golden circle and just join this experience for Snowmobiling if that's possible.
