But you know what happens with popular stuff. They tend to get old, worn down, often broken and lose their appeal in a jiffy.
This is exactly what is happening to the most popular tour operating in Iceland; the Golden Circle tour. This half or whole day tour from Reykjavik city takes you to Thingvellir National Park, Geysir area and Gullfoss area, all of which are unique in this world of ours.
But while those natural pearls will not lose their appeal these places are way too small and vulnerable for mass-market tourism. Nowadays, you will be lucky to find a parking spot in Thingvellir area. Luckier still to get into toilets around here without cues and delays. Not to mention all those pictures you are taking with whole heaps of people in every single frame.
All we can recommend is to come soon. Firstly because the government might charge extra for a visit later but much more importantly because if foreigners keep coming in droves Gullfoss, Thingvellir and Geysir will never be the same.
