Icelandic tourism has been developing fast, and most visitors go to a few places rather close to Reykjavík. The most famous scenic areas are all explainable in context with the convection rolls arrangement:
The Golden Circle includes Thingvellir, Gullfoss and Geysir. Thingvellir are located on the NS-axis of the polygon south of Langjökull, making up half of the West Volcanic Zone. At the east corner, Geysir hotspring area is found. About 10 kilometers east of there is Gullfoss.
The two main waterfalls are found in similar context, Hraunfossar accurately at the relevant corner of a mini-polygon. Laugarvatn and Hveragerði are then found on the main division line.
