I give this trip five full stars plus! The horseback riding hosted by a small family farm provided the most fun of the day. My husband, a very beginning rider, said it was the best part of the whole day. I am an experienced rider and really enjoyed the small group, riding these wonderful small horses at their special 'tolt' gait, and the incredible staff at the Horse Farm. They provided a delicious soup, breads, strong coffee, and pastries as well as answered my many questions about the kind and very willing Icelandic horses. Seven thumbs up on this part. The trip by bus to the Gulfoss waterfalls and the 'Geisers' were great. The driver was very safe and the guide provided rich information about the history and the geographic of the countryside and the places we visited. This was a well-organized tour. We saw everything promised with good time at each place to enjoy what we came to view. We were back in the city on time having learned about and seen some of the natural beauty outside of Reykjavik. Thank you Viator!
