This was an excellent tour. Everything was very easy in terms of pickup and getting on our way. There are several pickup locations in Reykjavik which seem to be universal and make it simple to get hooked up on your tour. All seem to be close to the common hotels. We were picked up at the stop next to our hotel and then to the tour terminal. We departed from there.
Our guide Dylan was super. His narration included the Iceland's history, geology, folklore, weather and he answered any questions asked on the tour. He was really knowledgeable. I liked his sense of humor and his willingness to try to adjust our day based on the weather and what would work best. Dylan kept us on time.
We stoped at two of the biggest, most famous waterfalls (the names are in tour description and are too long to spell out right now) but also saw many not the route. We also stopped at the black sand beach (beautiful) and a glacier. The best part was the second waterfall which you can walk behind - but be warned, you will get very wet- bring a rain poncho. Amazing and beautiful.
I recommend this tour. If you go, know it is a long day. I would not book on the same day as a northern lights tour. Also, have a good jacket and a rain poncho for the waterfall. My husband wore jeans over his thermals. I wore waterproof pants (also with thermals) and my coat. By the end of the day, we both all a bit soggy, so was most of our tour group. But the beauty was well worth the discomfort.
