The Golden Circle map in Iceland: itinerary, stops and distances

On a map, the Golden Circle draws an irregular triangle in the south-west of Iceland, starting from the Reykjavík region. You leave the capital on Route 36 heading north-east towards Þingvellir National Park, then swing east on Route 365 and Route 37 to the Geysir geothermal area, continue straight on for a few kilometres to the Gullfoss waterfall, then head back south-west on Route 35 to close the loop towards Reykjavík. The route therefore forms a ring: you never pass the same spot twice, which is the whole point of the circuit.

This is where many visitors trip up. Looking only at the distance to Gullfoss, the most distant site, they picture a simple out-and-back trip of about 120 km each way. Yet the map shows that Route 35 lets you return by a different path, without redoing the stretch already covered. Reading the loop correctly avoids this duplication and frees up time for secondary stops. The total comes to around 230 to 250 km depending on the detours, a distance covered in a rushed half-day or, more comfortably, over a full day.

The three pillars of the Golden Circle read in a natural order on the map. Þingvellir comes first: it is the national park where the rift between the North American and Eurasian tectonic plates is visible in the open air, and also the historic site of the old Icelandic parliament. Geysir comes next, at the heart of a steaming geothermal area where the Strokkur geyser erupts roughly every five to ten minutes. Finally Gullfoss, the "golden falls", marks the easternmost and most spectacular point, with its two tiers of water plunging into a canyon.

The sequence is not arbitrary: it follows the terrain and the road network. Going from Þingvellir to Geysir and then Gullfoss, you move inland and eastward, before Route 35 drops back down to the agricultural plain of the south-west to bring you back towards Reykjavík. Reckon on roughly two hours of cumulative driving for the whole loop, excluding stops. It is precisely those stops that determine whether you make it a three-hour expedition or a full day.

The table below summarises the main segments of the loop. Times are given as a rough guide, excluding stops and winter conditions: in winter, on icy or snow-covered roads, expect noticeably longer durations and always check road conditions before setting off.

These orders of magnitude show that pure driving stays modest. The real time budget is spent on site: Þingvellir deserves at least an hour of walking, Geysir around thirty minutes to watch Strokkur erupt several times, and Gullfoss as much again to walk down to the viewpoints. Adding driving and visits together, a full day offers a comfortable margin; a half-day forces you to choose and not linger.

The map holds several worthwhile pauses along the return on Route 35, without really lengthening the trip. The Kerið crater, a volcanic cone with reddish walls encircling a turquoise lake, sits on this road south of the circuit. The Faxi waterfall, quieter and less crowded than Gullfoss, is reached by a short detour between Geysir and the village of Flúðir. At Flúðir, the Secret Lagoon offers a geothermal bath that is more authentic and less packed than the large spas. And the Efstidalur dairy farm, between Þingvellir and Geysir, is known for its homemade ice cream.

These stops fall naturally into place depending on the direction of travel. Driving clockwise (Þingvellir first), you keep Kerið, Faxi and the Secret Lagoon for the end of the day, on the way back — handy for a warm bath before heading home. Here are the main detours to know, with the idea of not stacking them all up on pain of turning the loop into a marathon.

The direction of travel mainly affects the crowds. Most buses and organised excursions leave Reykjavík in mid-morning and start with Þingvellir, going clockwise. Taking the loop the other way round, or simply leaving very early, often lets you reach the major sites before the big flows. A study by Sæþórsdóttir, Hall and Wendt published in 2020 in the journal Sustainability ("Overtourism in Iceland: Fantasy or Reality?") highlights how Icelandic tourist traffic concentrates on a few flagship sites such as the Golden Circle, which makes shifting your timing all the more rewarding for avoiding the crowds.

In practice, leaving Reykjavík around seven or eight in the morning changes the experience: clear car parks, breathable Gullfoss viewpoints and Strokkur photographable without a forest of selfie sticks. Conversely, a late departure condemns you to cross paths with every group at the same moment on each site. Spreading out your stops over time too — visiting Þingvellir early, then leaving the secondary sites for the afternoon — eases the pressure and makes the day more pleasant.

The classic mistake is to treat the Golden Circle as a single destination rather than an itinerary. Keeping the map in front of you, you can visualise that Route 35 is the key to the return and that it crosses several secondary stops: you can then decide in advance which ones to keep, rather than discovering them too late once you have passed. It is this reading that turns an out-and-back trip you endure into a loop you master, where every kilometre driven leads towards something new.

What remains is to adapt the pace to the season and the vehicle. In summer, near-permanent light allows an early start and a stretched-out day without stress. In winter, short days and tricky roads mean tightening the programme around the three major sites and giving up the detours. In every case, a simple map annotated in advance beats improvising on the spot: it is what separates a smooth day from a race against the clock.
