Into The Glacier - From Þingvellir
5 hours and 30 minutes
Golden Circle
Walk down into Almannagjá on a still morning and the rock wall on your left is, geologically speaking, the edge of North America. The wall is tall, cracked and mossy, and the path runs along its foot like a street between buildings. Nobody tells you it will feel this quiet.
Þingvellir (often written Thingvellir) is where Iceland's two big stories meet. The North American and Eurasian plates are drifting apart here, roughly 2 cm a year, and the whole valley floor is stretched and split into fissures. It is also where Icelanders gathered for the Alþingi, their general assembly, from around 930 until 1798. That combination earned the park a place on UNESCO's World Heritage list, and it is the first stop on almost every Golden Circle day in Iceland.
Start at the Hakið viewpoint above the gorge, where the visitor centre is. From there you get the wide view: the rift valley, the lava plain and Þingvallavatn, the largest natural lake in Iceland, stretching off to the south. Then walk down through Almannagjá. It's paved, gentle and takes most people 15 to 20 minutes to reach Lögberg, the Law Rock, where a flagpole marks the spot where laws were once read aloud to the assembly.
Keep going and you reach Öxarárfoss, a waterfall that pours off the edge of the gorge. It's a short, easy detour. Worth it.
Down on the valley floor you'll find the little white church and the old farmhouse with its row of gables, plus a web of water-filled fissures. The most famous one is Silfra, where people snorkel and dive in glacial water so clear it hardly looks real. You can't just jump in, though. It's done with licensed operators only.
Stay on the marked paths. The ground between them is cut by cracks you won't see until you're standing over one, and in winter the paths themselves can be sheet ice. Bring microspikes or at least proper boots between November and March. The wind also funnels through the gorge, so a layer you think you won't need usually gets used.
Þingvellir is about 45 minutes' drive north-east of Reykjavík, which is why it tends to be the first stop of the day. Entry to the park is free, but you pay for parking: 1,000 ISK for a normal car, valid all day across the park's main car parks (P1, P2 and P5). Pay at the machines or online through Checkit.is. The cameras read your plate, so don't skip it.
Plan on at least an hour for the walk from Hakið down to Öxarárfoss and back. Add two to three hours if you're snorkelling Silfra, which includes the briefing and getting in and out of a drysuit.
Pro tip: if you're driving yourself, park at P1 by the visitor centre, walk down through Almannagjá to Öxarárfoss and then back along the gorge the same way. Most tour groups do it one way and get picked up at the bottom, so the return walk is often the emptiest part of the park.
Summer brings long evenings, and after the tour buses leave in the late afternoon the gorge is almost silent. The autumn colours in late September and October, when the dwarf birch and blueberry bushes go red and orange, are something locals drive out specifically to see. In winter the park is snowy, often icy and dark by mid-afternoon, but that darkness is useful. Þingvellir is far enough from city light that it's a common stop for northern lights tours between roughly September and April, when the sky is clear.
After Þingvellir, most people continue to Geysir and Gullfoss, with Friðheimar, Kerið or a hot spring bath slotted in somewhere. Most of the tours on this page stop at Þingvellir, from small-group Golden Circle days to Silfra snorkelling trips. Pick your pace below.
