I had an extraordinary time ! I was in Iceland for a day with a layover and decided to do this. The only thing I could say that might be taken as a negative was the way the trip was laid out. I was under the impression we'd take the horses to the lagoon. Instead, we were taken to the horse farm, where we rode for several hours through the countryside, taken back to the visitors' office, and then picked up to go to the lagoon. The lagoon was an additional fee and the trip could very easily fill an entire day. Also, when you start out on the horses, you think, "This is nothing," but then they start to run... watch out :D Your butt may be sore for a few days. Overall, I had a wonderful time. If you're in good heath and your body can take the horse ride, do it.
