A great trip that made for a special day overall. The Blue Lagoon is a one-of-a-kind experience that is absolutely not-to-be-missed whilst the visits to Gulfoss and Geysir were both interesting and valuable to those wanting to know a little more about Reykjavik and Iceland's history, especially if you get a great guide like we were fortunate too!
You might even get more for your money than expected if you are lucky - we also paid a visit to Pingvellir National Park, which wasn't expected but definitely appreciated!
The only drawback to the day the constant changing of buses, but this seems a tradition in Reykjavik/Iceland as it was something we experienced every day!
All-in-all it this is a trip well worth the money and taking - highly recommended.
