Raufarhólshellir formed about 5,200 years ago in the Leitahraun eruption, when lava kept flowing under its own cooled crust and then drained away, leaving a long hollow tube. At 1,360 metres it is the fourth-longest lava tube in Iceland, and one of the roomiest, up to 30 metres wide and about 10 metres high, so the standard tour involves no crawling or squeezing. It can only be visited with a guide.

4Geysir geothermal areaGeysir geothermal areaHot springs, with Strokkur erupting every few minutes.
Geysir geothermal areaGeysir geothermal areaStrokkur geyser erupting at sunrise

Geysir gave every geyser in the world its name. The original Great Geysir now erupts only rarely, sometimes after earthquakes, so the show is Strokkur, a short walk away. It throws boiling water 15 to 20 metres into the air every 5 to 10 minutes, and sometimes a good deal higher, so you will see several eruptions while you are here. Keep to the paths between the pools and stay behind the ropes, as the water is very hot.

Walking · short, flat pathsFacilities · visitor centre, café and toiletsTip · stand upwind of Strokkur to stay dry

Gullfoss, the Golden Falls, drops about 32 metres in two steps into a narrow canyon roughly 70 metres deep and 2.5 kilometres long. The water comes from the Hvítá river, which is fed by the glacier Langjökull. Glacial water often turns golden-brown in sunlight, and rainbows hang in the spray on bright days. A path with stairs leads down to a lower level, closer to the water.

Walking · upper viewpoint is easy; lower path has stairsFacilities · café, shop and toilets

Þingvellir is where Iceland's parliament, the Alþingi, first met in 930, and it lies in a rift valley where the North American and Eurasian plates are pulling apart. Chieftains gathered here every summer, laws were recited from the Lögberg (Law Rock), and the plain below still shows where the assembly booths stood. The lake beside it, Þingvallavatn, is the largest natural lake in Iceland. The park is free to enter and open all year.

About the Golden Circle lava tunnel tour

Raufarhólshellir is one of the longest lava tunnels in Iceland, formed around 5,200 years ago when a lava flow's outer layer cooled and hardened while the molten rock underneath kept moving and drained away. A walkway and boardwalk let you explore a stretch of it safely, past collapsed skylights and coloured mineral deposits on the rock.

The day starts with pick-up in Reykjavík and a short drive southeast to the lava tunnel, where your guide fits you with a helmet and headlamp before you go underground. From there the tour continues into the Golden Circle: Geysir, where Strokkur erupts every few minutes; Gullfoss, the wide two-step waterfall on the Hvítá river; and finally Þingvellir, where the North American and Eurasian plates pull apart.

It's a long day out, so pace yourself and bring something to eat or drink for the drive. Underground the temperature stays cool year round, while up top the weather at the Golden Circle stops can change quickly, especially in winter when daylight is short and paths can be icy.
