I did the Golden Circle tour with my mates at Intrepid Travel (you can see my pics on the website). We started out in the capital of Reykavik before venturing out to the Golden Circle—Thingevellir National Park, Strokkur Geysir, Gullfoss Waterfall. From there we hit the breathtaking Skógafoss waterfall and onto a definite trip highlight at the glacier lagoon of Jökulsárlón.
Hamilton, according to some, is the Waterfall Capital of the World. It does call 120 separate waterfalls home. The lady and I have been going to explore them as of late. Here are Webster's Falls and Tews Falls. The latter is only a few meters shorter than Niagara Falls, minus the tacky tourist traps.
