Kerið is one of the easiest extra stops on the Golden Circle and one of the most photogenic. Within a few minutes of parking you are standing on the rim of a volcanic crater, looking down at a blue-green lake ringed by red and orange slopes that feel completely different from Þingvellir, Geysir, or Gullfoss.
If you've seen Kerið mentioned in our Complete Golden Circle Guide, this is the deeper page on the crater itself: what it is, why it looks so different from much of Iceland's darker lava landscape, how long you need there, and when it actually improves the day instead of just padding it out.
What Kerið Actually Is
Kerið, often written Kerid in English-only itineraries, is a volcanic crater lake in the Grímsnes area of south Iceland. The crater is roughly 170 metres wide, 270 metres long, and about 55 metres deep, with a lake at the bottom whose level shifts through the year with the groundwater table.
The reason it photographs so well is simple contrast. Instead of the black-and-grey palette many visitors expect in Iceland, Kerið combines rusty red volcanic rock, green moss, and a vivid aquamarine lake. That color contrast makes it one of the few Golden Circle stops that looks dramatic even in a single, quick overview shot from the rim.
Why It Is So Geologically Distinct
Kerið is widely described as a collapsed volcanic cone rather than a purely explosive crater. The basic theory is that a cone formed, emptied much of its magma chamber, and then lost structural support, causing the top to sink and leave the bowl shape visible today.
It is also relatively young by Icelandic standards, usually estimated at somewhere between 3,000 and 6,500 years old. That youth helps explain the color. The mineral-rich slopes have not had enough time to weather into the darker tones you see in many older Icelandic volcanic landscapes, so the crater keeps its unusual red-orange walls.
Kerið works because it is quick. You do not need a long hike, special gear, or an extra transfer. It gives you one more distinctly Icelandic landscape without turning the Golden Circle into a second full itinerary.
A Short Stop with a Few Good Stories
Despite being a small stop, Kerið has a couple of details guides like to mention. The bowl shape produces notably good acoustics, so the crater has occasionally been used as a concert venue. The most famous example is Björk's 1987 performance on a floating stage on the lake.
There is also a layer of folklore around the crater and nearby water-filled volcanic features, with stories of hidden underground connections and water spirits. Whether or not you care about the folklore, those stories fit the place: Kerið feels a little more mythic than a simple parking-lot stop has any right to.
Other Experiences You Might Enjoy
Kerið is most often paired with the classic Golden Circle, but it also fits naturally with a soak at the Secret Lagoon, lunch at Friðheimar, a stop at Laugarvatn Fontana, or a longer route through Selfoss and back to Reykjavik. The auto widget below is primed with those nearby experiences and route extensions:
What Visiting Kerið Feels Like
The visit is simple. You park, pay the small entrance fee, walk a short distance to the rim, and the full crater opens almost immediately in front of you. That instant payoff is part of the appeal, especially if you are traveling with limited time, children, or anyone who is not enthusiastic about longer walks.
The rim walk takes roughly 10 to 20 minutes at an easy pace, or a bit longer if you stop often for photos. It is mostly straightforward, though some sections are loose gravel and can get slick when wet.
The descent to the lake uses a staircase down one side of the crater. It gives you a very different perspective, looking back up at the colored walls from the water's edge. In dry conditions it is easy for most visitors. In rain, ice, or snow it can be the trickiest part of the visit.
Practical Visitor Information
Getting there: Kerið sits just off Route 35 in the Grímsnes area, around 70-75 km from Reykjavik. On the classic clockwise Golden Circle loop it usually falls naturally on the way back south, which is why so many tours include it without adding much total time.
Entrance fee: Kerið is on privately owned land, so there is a small admission fee, commonly around 600 ISK per adult. Parking is usually free. The fee supports maintenance and helps protect the rim and paths from erosion.
Facilities: Expect a parking area, ticket point, and basic restrooms, but not a big visitor center. Kerið is a quick natural stop, not a major service hub. If you need a longer break, food, or fuel, build that into another part of the day.
Accessibility: The rim is much easier than the lake descent. Visitors with limited mobility can still get the main visual payoff from the upper path, but the stair section down to the water is not the right call for everyone.
What to wear: In dry summer weather, ordinary sturdy shoes are usually fine. In winter or after rain, traction matters more. If you are unsure what conditions will feel like across the whole route, our Golden Circle packing list covers the practical clothing tradeoffs.
If You Want a Smaller-Group Kerið Tour
The most popular Kerið tour is the large-group classic loop, but this smaller-group version works better if you care more about pacing and guide interaction than simply ticking off the stop list:
When Kerið Improves the Day
Kerið is worth adding when you want one more visual highlight and still need to stay efficient. That is why it works so well on first trips to Iceland, cruise-ship day tours, and guided Golden Circle loops where you want something beyond the classic three but not another major activity.
It matters less if you are already adding a longer experience such as the Secret Lagoon, Silfra snorkeling, or a big spa detour. In those cases, Kerið can start to feel like one extra stop too many unless you know you want the crater specifically.
Seasonal Notes and Photography
Kerið is attractive year-round, but the look shifts a lot. In summer, the lake color and red slopes are at their most vivid. In autumn, grasses around the rim add warmer tones. In winter, snow on the rim creates a striking high-contrast frame around the blue or partially frozen lake below.
The cleanest classic photo is from the rim with a wide view of the full bowl. The most dramatic second angle comes from the lake level, looking back up at the steep walls. If conditions are wet or icy, the upper rim is the smarter place to prioritize.
Frequently Asked Questions
Yes. Kerið is one of the best quick add-ons because it adds a completely different landscape to the day without much extra driving. It is especially worthwhile if you want a high-contrast photo stop beyond the classic three attractions.
Most visitors spend 30 to 60 minutes there. That is enough for the rim walk, photos, and the staircase down to the lake if conditions are comfortable.
Yes. Kerið is on private land and charges a small admission fee, while parking is usually free. The fee helps maintain the site and protect the crater from erosion.
Usually yes. There is a staircase to the water's edge, but it can be slippery in rain or winter ice, so not every visitor will want to do the lower section every day of the year.
