Tumbling waterfalls, erupting geysers, and wild landscapes sprawling across 2 separate tectonic plates—there's a reason Iceland's Golden Circle is the country's most iconic tour. Discover the natural wonders of Thingvellir National Park, the Geysir hot springs, and the Gullfoss waterfall during this full-day road trip.

Departing from Reykjavik, ride off in the direction of Thingvellir National Park. A UNESCO World Heritage Site, this rugged wilderness is famed for its gorgeous rift valley, which has formed as 2 tectonic plates drift gradually apart. Listen to your guide describe how this location was the meeting place of Iceland's first general assembly in the year 930 as you snap photos of the greenery-blanketed rocks and deep blue water.

From there, continue on to Gullfoss, where the wide, rushing waters of the Hvítá glacial river plunge abruptly into a crevasse as if vanishing from the surface of the earth. Listen to the roar of this vast cascade, and feel the icy mist on your face.

Continue on to the geothermal area of Haukadalur, home to the Geysir that named all other geysers. Watch the regular eruptions of Strokkur as the burbling hot spring bursts skyward, and marvel at bubbling mud pots and hissing steam vents ringed with colorful algae and minerals before looping back to Reykjavik.
