ゴールデンサークルとケリズ火口湖｜日帰りツアー

The Golden Circle is a 300 kilometre (186 mile) route to the three most popular natural attractions in Iceland: the Geysir Geothermal Area, Gullfoss Waterfall and Þingvellir National Park.

This sightseeing trail is easy to do within half a day from Reykjavík, either by self-drive or on one of many tours. Some of these tours have additional activities, such as snorkelling or snowmobiling, or are conducted in a unique style, such as by helicopter, or under the midnight sun.

Within the three locations of the Golden Circle are some of the clearest examples of Iceland’s fascinating geological forces, magnificent landscapes, and rich culture.

The Geysir Geothermal Area

The Geysir Geothermal Area is a hot-spring haven in Haukadalur Valley. As could be guessed, it is home to a famous geyser, the name of which has named all others: Geysir itself.

Though this feature is currently in a phase of inactivity, its neighbour Strokkur more than makes up for it. Every five to ten minutes, it blasts a column of boiling water to heights that can reach over 40 metres (131 feet).

The surrounding area is dotted with fumaroles, hot springs, and mud-pits. There are also two other smaller geysers, Smiður and Litlí-Strokkur, that can be easily visited, as well as a hotel, restaurant, cafe and gift shop across the road.

Gullfoss Waterfall

The 'Golden Waterfall', Gullfoss one of the most beautiful and powerful waterfalls in Iceland, plummeting 32 metres (105 feet) in two tiers into the river gorge of the popular rafting river Hvítá. It is just a ten-minute drive from Geysir and is the furthest point on the Golden Circle from Reykjavík.

Gullfoss was very almost lost in the early 20th century when British developers sought to harness its incredible power for geothermal energy. Though they got the lease to the land, allowing them to go ahead with their plans, they met an unlikely adversary: the daughter of the farmer who owned it, Sigríður Tómasdóttir.

This resilient woman refused to see the waterfall, to which she and her sisters paved the first path, destroyed. She, therefore, walked over 200 kilometres (124 miles) to Reykjavík and back multiple times to meet with a lawyer in order to help change the decision.

Though the process was arduous and took years, eventually Sigríður managed to exhaust the resources of the businessmen and they withdrew their plans. Because of her, all Icelandic waterfalls are now protected from foreign investors, and she is considered one of Iceland’s first environmentalists and most important historical people.

Thingvellir National Park

The largest attraction of the Golden Circle is Þingvellir National Park. The Icelandic parliament was founded here in 930 and remained until the year 1798 before moving to Reykjavík, making it the original site of what is now the world’s longest ongoing parliament.

Today it is a UNESCO World Heritage Site and one of the most important places to visit in Iceland. This is not just for its historical and cultural values, but for also its magnificent landscape and dramatic geology.

Þingvellir is surrounded by a beautiful mountain and volcanic ranges, as it is located in a rift valley directly between the North American and Eurasian tectonic plates. This makes it one of the few places in the world where you can walk between the continents, in the Mid-Atlantic Rift.

The daring and qualified even have opportunities to snorkel or scuba dive in this no-mans-land, in a ravine filled with crystal-clear spring water called Silfra. The visibility here can exceed 100 metres (328 feet), revealing incredible geological sites. Though it never freezes over due to the constant flow of water into it, it is 2°C (35°C) throughout the year, thus underwater explorers are always equipped with protective suits.

Other sites of note are the magnificent Almannagjá gorge, which you can walk down into to reach the rift valley from the North American tectonic plate, and the beautiful lake Þingvallavatn, the largest lake in Iceland, which gleams to the south of the National Park.

Surrounding sites

Due to its convenient location in south-west Iceland, it is easy to visit the Golden Circle alongside with many other sites. Those seeking relaxation could head to the Secret Lagoon in Flúðir or Fontana Spa in Laugarvatn, those seeking adventure could book a trip to the ice tunnels of Langjökull glacier, and those seeking culture could visit the Sólheimar ecovillage. For more natural beauty, you can visit the nearby Kerið crater lake.

There are many tours that include such bonuses, but if driving yourself, you should check out this guide to great detours off the Golden Circle.

Geysir is a famous hot spring in the geothermal area of Haukadalur Valley, found in south-west Iceland.

Making up just one of the attractions along the world-renowned Golden Circle sightseeing route, alongside Þingvellir National Park and the mighty Gullfoss waterfall, Geysir is most well-known for having lent its name to geysers all around the world.

Geography 

Though Geysir itself is rarely active these days, Haukadalur Valley boasts a plethora of hot springs and geysers, including the powerful Strokkur, Smiður and Litli-Strokkur.

Strokkur is, arguably, the country’s most famous hot spring, shooting vast jets of boiling water from 20 metres (65 feet) up to 40 metres (130 feet) high. Don’t worry about missing this incredible spectacle of nature, as Strokkur erupts every five to ten minutes; just make sure to have your camera ready.

Geysir is much larger, but years can go by between eruptions here; it is currently in an inactive phase. When it does erupt, the water can shoot up in the air as high as 70 metres (230 feet).

Just a few minutes walk north of Geysir are a wealth of fumaroles emanating steam and gas into the cool Icelandic air. Aside from watching the hypnotic pillars of steam, you will also be able to observe the yellow sulphuric stains along the fumaroles themselves, a result of the earth’s minerals crystallising around the rock bed.

At the southern part of the valley, Þykkuhverir, you’ll find various bubbling mud pots. These spooky brown cauldrons are actually fumaroles that boil up through the loose ground; after a dry spell, these mud pools are likely to transform into a hardened fumarole.

Nearby Attractions 

About two kilometres (one mile) from Geysir is a preserved natural pool called Kúalaug. It has room for three to five people at a time, but care should be taken, as the area around the pool is very delicate. The temperature is 39-43°C (102-109°F), depending on where you are positioned in the pool.

The water is slightly muddy, as the pool is built on soil, and the bottom is slippery due to algae, so caution is advised when relaxing here.

Haukadalur has also seen a rise in reforestation in recent times thanks to continued experiments and research in the area. Today, Haukadalsskógur is one of the largest forests in south Iceland, boasting accessible walking paths (also for wheelchair users), fascinating vegetation and The Tree Museum, built in the memory of forester Gunnar Freysteinsson.

History 

Haukadalur has been inhabited and used as a church site since the Age of Settlement. Given its historic value, it should be noted that scholar, Ari “The Wise“ Þorgilsson, grew up here; it was also where the first pastoral school in Iceland was built.

The current wooden church was last rebuilt in 1938 but its architectural style dates back to 1842, making it well worth a visit to see how Iceland looked before industrialisation.

For accommodation, Hotel Gullfoss is approximately 7 kilometre from the Geysir area, and closer still is Hotel Geysir on the other side of the road from the attraction, where you will also find a restaurant, café and a souvenir shop.

Gullfoss (translated to ‘Golden Falls’) is one of Iceland’s most iconic and beloved waterfalls, found in the Hvítá river canyon in south-west Iceland.

The water in Hvítá river travels from the glacier Langjökull, before cascading 32 meters (105 feet) down Gullfoss’ two stages in a dramatic display of nature’s raw power. This incredible site is seen by most visitors, as it is on the Golden Circle sightseeing route.

Because of the waterfall’s two stages, Gullfoss should actually be thought of as two separate features. The first, shorter cascade is 11 metres (36 feet), whilst the second drop is 21 metres (69 feet). The canyon walls on both sides of the waterfall reach heights of up to 70 metres (230 feet), descending into the great Gullfossgjúfur canyon. Geologists believe that this canyon was formed by glacial outbursts at the beginning of the last age.

In the summer, approximately 140 cubic metres (459 cubic feet) of water surges down the waterfall every second, whilst in winter that number drops to around 109 cubic metres (358 cubic feet). With such energy, visitors should not be surprised to find themselves drenched by the waterfall’s mighty spray.

As mentioned, Gullfoss makes up a part of the highly popular Golden Circle sightseeing route, alongside Geysir geothermal area and Þingvellir National Park. Many Golden Circle tours include additional activities that can be taken from Gullfoss, such as ascending the mighty nearby glacier Langjökull and entering its ice tunnels, or snowmobiling along its gleaming surface.

History

In the early days of the last century, Gullfoss was at the centre of much controversy regarding foreign investors and their desire to profit off Iceland’s nature. In the year 1907, an English businessman, Howell, sought to utilise the waterfall’s energy and harboured ambitions to use its energy to fuel a hydroelectric plant.

At the time, Gullfoss was owned by a farmer named Tómas Tómasson. Tómas declined Howell’s offer to purchase the land, stating famously “I will not sell my friend!” He would, however, go on to lease Howell the land without the knowledge of a loophole that would allow him to proceed with his plans.

It was Tómas’ daughter, Sigríður Tómasdóttir, who would lead the charge to stop Howell’s ambitions. Having grown up on her father’s sheep farm where she helped pave the first road to Gullfoss, she sought to get the contract nullified, hurriedly saving her own money to hire a lawyer.

The ensuing legal battle was an uphill struggle; the case continued for years, forcing Sigríður to travel many times by foot to Reykjavík, a distance of over 100 kilometres (62 miles). Circumstances became so difficult that Sigríður threatened to throw herself into the waterfall if any construction began.

Her tenacity, however, resulted in success. In 1929, Howell’s withdrew from the lease, unable to keep up with the costs and difficulties of his plan. The waterfall fell back into the hands of the Icelandic people.

Today, Sigríður is recognised for her perseverance in protecting Gullfoss and is often hailed as Iceland’s first environmentalist. As such, she is one of the most famous figures in Iceland’s history. Her contribution is forever marked in stone; a plaque detailing her plight sits at the top of Gullfoss.

Interestingly, the lawyer who assisted Sigríður, Sveinn Björnsson, went on to go down in history too; he became the first president of Iceland in 1944.

Restaurant / Cafe

Besides Gullfoss, visitors can enjoy the views from Gullfoss Cafe, a locally run delicatessen that serves a wide variety of refreshments and meals. The menu has options to tantalise everyone’s taste buds: hot soups, sandwiches, salads and cakes. There is also a shop on site where visitors’ can browse and purchase traditional Icelandic souvenirs.

Þingvellir National Park is the only UNESCO World Heritage site on the Icelandic mainland and one of the three stops on the world famous Golden Circle sightseeing route, alongside the Haukadalur Geothermal Valley (Geysir) and Gullfoss Waterfall. Just to the south of the park is Þingvallavatn, Iceland’s largest natural lake.

Geography 

The first thing that visitors to the National Park notice is its sheer aesthetic beauty; dried magma fields, covered in Icelandic moss, sit carved by glacial springs and surrounded by a bowl of ancient mountain peaks.

Two of the greatest attractions in the park are the exposed North American and Eurasian tectonic plates; it is one of the only regions in the world where you can see geology such as this on land.

Visitors are encouraged to walk along the North American tectonic plate, where they can read more about the area’s fascinating formation and history, before descending into the valley below.

History 

Þingvellir can be anglicised to ‘Fields of Parliament’, a nod to the area’s fascinating history and relevance to Icelandic culture. It is here, after all, that the world’s first democratically elected parliament that remains functioning, Alþingi, was formed in 930 AD.

It may seem unlikely that Vikings would want to be under such an uncombative government, but the thirty or so clans that lived in Iceland at the time sought to prosper in their harsh new environment.

The first gathering was such a success that the meetings became annual, and it became a place where disputes were settled, criminals were tried, and laws to the benefit of all were laid down.

This saw the birth of the Icelandic Commonwealth, a time of independence and freedom for the Icelandic people before they became constituents of the Norwegian monarchy. Sessions would continue to be held at Þingvellir until 1798.

Though the parliament was removed by the Danish at this time, it returned 1845 to Reykjavík.

Silfra Fissure 

Þingvellir is one of the most widely visited attractions in Iceland, in large part due to the fact that it is home to the glacial spring, Silfra fissure, one of the top ten sites in the world for snorkellers and scuba divers.

Silfra (meaning ‘Silver’) is a submerged ravine within the park, boasting visibility of up to 100 metres (328 feet) and a temperature just above freezing. Participants in these tours will be attired at the Silfra carpark in neoprene hoodies and gloves, as well as an undersuit and drysuit for thermal protection.

Kerið is a volcanic crater lake in Grímsnes, South Iceland. It is close to the three major sites that comprise Iceland’s world-famous Golden Circle sightseeing route, and makes for the perfect detour.

Kerið and the Golden Circle

The Golden Circle is Iceland’s most popular tourist route, which it is possible to explore on many tours in many different ways, or to traverse yourself. Its three main highlights are Gullfoss, or the ‘Golden Waterfall’; the Haukadalur Geothermal Valley, with its many springs and geysers; and Þingvellir National Park, the only UNESCO World Heritage Site on Iceland’s mainland and the birthplace of the country’s parliament.

Many operators define their tours from the others with extra stops, and Kerið crater is the most popular of these. It is approximately 40 minutes drive from Þingvellir and Haukadalur in different directions, allowing visitors to return to Reykjavík

If travelling to Kerið crater alone, please be aware that there is a small charge to walk upon it, of 400 ISK (about two Euros, or three US dollars). This is only to help the landowners preserve and protect the crater; after all, it is on privately owned land.

Other sites you may want to detour on when travelling the Golden Circle are the Sólheimar ecovillage, the Fontana Spa in Laugarvatn, the Secret Lagoon in Flúðir, and the Friðheimar tomato and horse farm.

Geology of Kerið

Kerið is approximately three thousand years old, making it approximately half the age of most volcanic calderas found in Iceland. This is the major reason as to why Kerið’s slopes are red in colour, rather than a volcanic black; the iron deposits are, geologically speaking, fresh.

This vivid redness is part of the appeal of visiting this crater. The crimson rocks contrast dramatically with their surroundings, particularly the intense azure colour of the waters within the crater lake, and the verdant bursts of vegetation.

Kerið is approximately 55 metres (180 feet) deep, 170 metres (558 feet) wide and 270 meters (886 feet) in circumference. It is possible to take a path right to the crater’s edge, to fully encircle it, and to descend down to the pristine waters of the crater lake.

Many crater lakes can found in this area, a region known as Iceland's Western Volcanic Zone. The area surrounding it is of barren, stark lava fields, further illustrating the volcanism of the region.

Scientists believe that Kerið was once a cone-shaped volcano. Upon eruption, it is widely believed that the volcano depleted its magma reserve, causing the foundation to fall in upon itself and result in the formation it has today. Of course, this was two thousand years before settlement, so no one is quite certain.

At some point in the centuries following the collapse, Kerið crater filled with water. The resulting lake is between seven and fourteen metres deep, depending on the time of year and the amount of rainfall.

The reason it is so vividly coloured is because of the minerals from the rocks, seeping into and dyeing the water the aquamarine colour for which it is renowned.
