On our first day in Iceland we decided to do the Golden Circle drive. It's about 200 miles and starts and ends in Reykjavik. We picked up our hired car (which we named Poppy) and set off for the Thingvellir National Park.
This location is famous for 2 things. First of all it was the place where the North American and Eurasian plates meet - mostly this runs through the middle of the Atlantic Ocean, but here in Iceland the plates are splitting apart creating deep fissures in the ground. In fact you can snorkel or scuba dive through the icy glacial waters of one of these fissures if you want to (I didn't!)
The national park is beautiful and we were lucky it was such a beautiful day. We walked down through the gorge where you could see the plates on either side, right up to a picturesque waterfall.
Another important fact about the national park is that it was the location of Iceland's first parliament, that dates back to 930 AD. Chieftans gathered here to discuss the laws and put people on trial (punishments such as 3 years of exile for stealing were decided upon here).
We continued to walk around the park, stopping at the visitor's centre for a very interesting interactive exhibition, and finally back past a lovely little church.

Back at the car again, we set off for one of the geyser areas in Haukadalur about 60 km away. In this park there is the famous Geysir - the term geyser was named after this one - and another very active one called Strokkur. It was a really interesting place as you could see boiling water bubbling out of the ground and steam rising up from mud pools.
Although Geysir no longer erupts, Strokkur explodes every few minutes with boiling water shooting high up into the air.
Our next stop along the Golden Circle was Gullfoss Waterfall. Gullfoss means "gold waterfall" in Icelandic. The river falls 100 feet into a crevice in the earth, producing mist, spray and rainbows. It's all very magnificent.
We parked at the bottom carpark and then walked up to the falls, after which we climbed up a staircase and walked along to top of the waterfall.
This was the furthest we travelled out of Reykjavik, after that we turned round and went a different route back via the Kerid Crater Lake. In fact this was the only thing we had to pay for the whole day. This is a red volcano crater which is covered in bright green vegetation and you can walk around it, though it's a little bit of a scramble at times. The evening was warm and sunny and the views were lovely.
At one time this was a typical cone-shaped volcano, but the top has now collapsed into the empty magma chamber and the bottom is now filled with a lovely blue shade of water that contrasts with the red and green of the crater.
Continuing back to Reykjavik we decided to take the scenic route through the Nesjavallaleid geothermal area. This was a lonely and beautiful road with a couple of great viewpoints to stop and take in the magnificent scenery.
