Route 1 circles Iceland in 1,332 kilometers. Most drivers do it in seven to ten days, which is enough time to complete the loop but not quite enough to stop thinking of it as a loop. The island imposes a different mental pace once you are out of Reykjavik — distances become abstract, weather becomes the primary variable in every decision, and the absence of trees, visible from the road through virtually the entire interior and south, produces a landscape that reads as both ancient and post-apocalyptic simultaneously.
The south coast is where Iceland front-loads its drama for drivers heading clockwise from the capital. Seljalandsfoss is the waterfall you can walk behind — a narrow path curves around the back of the curtain, and for about thirty seconds you are inside the falls looking out through moving water at the green plain and the ocean beyond. The path is wet and the rock is slippery and the experience is worth every bit of it. Skógafoss, a few kilometers east, is taller and wider and produces a permanent rainbow in sunshine. Both waterfalls are roadside and require no hiking ability whatsoever.
The black sand beach at Reynisfjara is the most dangerous tourist site in Iceland by visitor incident count. The Atlantic waves here come without warning — what looks like calm water can produce a surge that reaches thirty meters inland in seconds. The basalt columns behind the beach, formed by lava cooling against the sea, are geologically identical to Giant’s Causeway in Northern Ireland. The arch-shaped cave at the north end of the beach, Hálsanefshellir, frames the sea stacks called Reynisdrangar — rock formations that Icelandic folklore insists are trolls caught at sunrise. Stay well back from the waterline.
Vatnajökull is the largest glacier in Europe by volume and covers roughly eight percent of Iceland’s entire surface. The outlet glaciers descending from its edges are accessible from the Ring Road without specialized equipment. Svínafellsjökull was used as a filming location for both Game of Thrones and Interstellar, though the landscape renders fiction redundant. Jökulsárlón glacial lagoon, where the glacier calves directly into a tidal lake connected to the sea, is the visual centerpiece of the southeast: blue and white icebergs drift in black water under a sky that can turn any colour without much notice.
The Eastfjords are where the Ring Road earns its reputation for demanding attention. The road winds through a series of narrow fjords, climbing to exposed headlands and descending to small fishing villages that have been catching Arctic char since the settlement era. The east receives fewer visitors than any other region and has proportionally fewer tourist services — which is either a problem or the point, depending on why you came.
The north contains Mývatn, a lake formed by lava flows roughly 3,800 years ago and still surrounded by active volcanic features. The Námaskarð geothermal field east of the lake — boiling mud pools, sulphur vents, ground that hisses and shifts — is the closest most people will get to watching geology happen in real time. Dettifoss, accessible on a rough road off the Ring Road, is the most powerful waterfall in Europe by flow rate. The sound reaches you before the falls come into view.
Northern lights are the reason most first-time visitors choose Iceland over other sub-Arctic destinations. They are a phenomenon of clear, dark skies between September and March, and they appear on their own schedule with no regard for your itinerary. The Ring Road removes you from light pollution quickly once you leave any town, and pulling off on a gravel turnout at midnight to watch the aurora fold across the sky is the kind of experience that justifies the drive entirely — on the nights it happens.
