We did the Silfra snorkeling trip. Our guide was Val; he was prompt in picking us up, he was extremely patient and helpful in getting everyone into their dry suits. Also, allowed plenty of time for us to take pictures after we finished. We were very pleased with the entire experience and this trip was $100 less than another one we first looked at, for the two of us. Truly is a once in a lifetime type of experience. Highly recommend Iceland Adventure Tours!
