Our tour started at one of the easily identifiable pickup points in downtown Reykjavik, where we met our tour guide (who suggested we pronounce his name as 'Good John'). Good John was an excellent tour guide, showing us not just the destinations we had in the brochure, but also some of his personal favorites while also providing color commentary about the surroundings as we blitzed through Iceland's south coast.
I personally found that the tour was very well-timed as well. I felt like we were afforded enough time at each of our destinations to explore, take some good photos, check out the gift shops, and return to our bus comfortably. Perhaps we had some favorable traffic conditions, but it felt like we narrowly beat 'the good light' to every destination, making for the curious (and tremendously welcome) sensation of arriving somewhere just as the sun came out to bask it in a simple gorgeous shade of warmth.
Something else I was impressed by was how accommodating Arctic Adventures were. Our tour company sent them the wrong shoe sizes and when we discovered this on the first day, I was quite surprised to see that Good John had talked to his fellow tour operators and traded his way into getting my partner and myself a set of proper boots for our Glacier.
There were a few minor negatives that I will mention for the sake of being complete, but I would absolutely describe this as a 5/5 experience.
1.) The beds were a little thin. I found the first place we stayed had a slim bed and thin pillows which made for a poor night of sleep.
2.) If you opt to bring a backpack, try to condense what you have as seating on the bus is quite limited. If possible, I'd suggest trying to get to the bus early in the morning so you can pick your seat (we found sitting near the front especially good as we got to ask questions, and we had more leg room).
3.) I realize this review is very dependant on the guide you're assigned. We had a fantastic one, and I'm inclined to believe that Arctic Adventures realizes that when they hire their team members. I can certainly speak to how excellent Good John is, but beware that your experience may differ (as ours did with the very next Arctic Adventures tour we did).
But in conclusion, if you're alright with a tour group of about 18 people and cramming into a fun-filled 2 day adventure down the south coast of Iceland, Arctic Adventures knows what they're doing.
