Itinerary for the Golden Circle tour
A short drive from Reykjavik is Nesjavellir and Hengill volcano where you visit a geothermal power plant, and learn about how it provides Reykjavik with hot water and electricity without polluting.
Next stop is Thingvellir national park, where the Icelandic parliament was founded in 930 AD. This is where the Eurasian and North-American tectonic plates meet, having formed a crevice while slowly drifting apart.
After crossing Lyngdalsheidi you get to Gullfoss waterfalls. The name translates to "Golden Waterfall", and the "gold" is the rainbow that forms on sunny days over the waterfall as it cascades down the Hvita River in two steps.
After enjoying lunch you head to Geysir hot spring area. There you find Geysir, from where the English word "geyser" gets its meaning, and the geyser Strokkur which spouts boiling water 25-30 meters into the air every 5-10 minutes.
Optional: You can go for an hour long horseback riding or ATV tour from Geysir and explore the beautiful Haukadalur region. The ATV tour is more action-oriented while the horseback riding tour is more relaxed.
On the way back to Reykjavik you stop at Kerid Crater Lake. Because of minerals in the water it's an opaque and aquamarine colour. Once back in Reykjavik your driver guide will drop you off at your hotel or a restaurant of your choice.
