Simply put, Iceland’s famous Golden Circle is a popular route between three of the island's most visited attractions. Usually done as a day trip, the route starts in Reykjavik and takes you south and inland, to the Þingvellir National Park. There you enter the Geyser geothermal area with the Strokkur Geyser being most eager of the bunch. Finally, you arrive at to the 32-metre tall Gullfoss waterfall in the canyon of the roaring Hvítá river. Many tour agents and travellers themselves like to make extra stops along the way to see a geothermal power plant or spend a few hours at one of the spas. You could rent a car and drive between the landmarks at your own speed. In summer, you could even use the long daylight hours to avoid the crowds that tend to come earlier in the day. If you can pick your own route, don't miss the Kerid Crater Lake — a scenic lake that occupies a 3,000 years old volcanic crater that you can easily reach on foot.

Renamed from Kestner-Museum to Museum August Kestner, in order to avoid confusion with the local art gallery Kestnergesellschaft, this museum was founded in 1889 and, in 1962, rebuilt in its present and highly interesting form. Centered on the collections of August Kestner himself as well as his nephew Hermann, the exhibitions contain four different categories of antiquities: Ancient Egypt, Classical Antiquity, Numismatics and Handicraft.
