I played tourist today and drove the Golden Circle. First I visited, and walked around the site of the Parliament Assembly in the Thingvellir National Park. This is a stunning site and was used as assembly fields from 930 AD on, shortly after the settlement of Iceland. It was also used for judicial proceedings including executions. Today it is a park with beautiful vistas and many walkways.
The next stop was a famous waterfall, quite impressive but also rather crowded.
Geysers are called geysers because there is a fountain called The Great Geysir in Iceland. Unfortunately, it is not active right now, but close to it is a smaller one that regularly blows.
I stopped for a recovery session in the hot pool at Secret Lagoon, which is not all that secret anymore, but was not too terribly crowded.
