Review for Treasure Island Resort & Casino Review For Blue Lagoon Google User Apr 21 '18 at 16:24 Wonderful experience that was much better than we expected. In April the tourist numbers were low, queues were short and the staff were really helpful. Good quality amenities and the water temperature was perfect. Take your swimmers, rent a towel and get a beer to drink in the warm waters. Well worth the cost (a rare comment in Iceland) of the ticket which included all of this and the return bus trip.
