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.
Geysir, 
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.
Gullfoss, 
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.
Another major reason as to why Þingvellir is considered so important to Icelanders is the fact that this is where the decision was made to abandon the belief of Paganism and the Norse Gods; the people adopted Christianity in 1000 AD under threat of invasion from Norway.
This turning point in history was left to the pagan lawspeaker, Þorgeir Þorkelsson, who rested on the choice for one day and one night before reappearing to share his decision.
To symbolise the country’s change, he threw idols of his old deities into the northern waterfall Goðafoss, the name of which translates to ‘Waterfall of the Gods’.
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.
Þingvellir, 
Silfra is a fissure filled with fresh spring water within Þingvellir National Park, and one of the country’s most cherished wonders. Snorkelling and diving in its crystal-clear waters is an experience that is both thrilling and relaxing, and it is now considered to be one of the top five dive sites in the world. It takes around an hour to reach Silfra from Reykjavík.
Geography of Silfra

Silfra fissure opened in 1789, due to the movements of the tectonic plates that frame Þingvellir National Park. The North American and Eurasian plates, which run all the way through Iceland, separate at about 2 centimetres per year, and as they do, they tear open fissures in the land between them.
Some of the ravines fill with water travelling underground through the porous lava fields in the area, originating from Langjökull glacier about 60 kilometres north. It can take the water up to a century to reach Silfra and this long filtration process results in the water being both extremely clear and drinkable.

Because the water travels underground, it maintains a constant temperature of two to three degrees Celsius and does not freeze over immediately at the source of the spring. Snorkelling and diving tours are thus open throughout the year.
The clarity of the water is what draws most visitors. The visibility can extend to over 100 metres, allowing you to see the canyon walls and bottom like you are floating over a great cathedral.
The last colour that water absorbs is blue, which means that when you look forward in Silfra, it is as if you are looking into an ethereal, vivid, azure world. The clarity also means that sun-rays refract through the surface of the water, creating rainbows on Silfra’s bed when the weather allows.
Snorkelling in Silfra

Snorkelling in Silfra fissure is a highly enjoyable activity, but you must meet some prerequisites to be able to join. These are as follows:
- You must be able to swim
- You must be over 16
- You must be in good physical health
- You must be at least 145 centimetres and 45 kilograms
- If you are over sixty, you will need a medical waiver
- If you are over forty-five with a history of heavy alcohol use and pipe smoking, you will also need a waiver
The most common option for snorkelling is to conduct it in a drysuit. Drysuits work with a fluffy undersuit to keep your body free from water and insulated against the cold, making the task of swimming through the near-freezing temperature more than achievable.
While drysuit snorkelling is the most comfortable and popular option, a few tours allow you to go through Silfra wearing a wetsuit. Wetsuits, made of neoprene, allow water to surround your body in a thin layer, that your body then heats up and uses to protect you. Though they grant you more flexibility, they are not so warm, so this should be done by the daring; you will also need to be at least 50 kilograms to snorkel in a wetsuit.
In all tours, you wear neoprene on your head and hands to allow for better mobility, a mask and snorkel, and a pair of fins, all of which are provided on site. The course of Silfra takes approximately forty minutes, and there is a gentle current throughout, meaning it requires minimal energy to traverse.
Diving in Silfra

Diving through Silfra gives an extra dimension to its beauty, as you will be able to look up and see the sun glistening upon the surface as you cruise through the crystal clear waters. However, considering the risks associated with diving in cold water and cumbersome equipment, all who partake must meet all the requirements above, as well as one of the following:
- You must be a qualified diver with a certification in a drysuit speciality, OR
- You must be a qualified diver with at least 10 logged dives in a drysuit conducted over the past two years, signed by an instructor or divemaster.

Kerið is a volcanic crater lake in the Grímsnes area of South Iceland. It is close to the three major sites that comprise Iceland’s world-famous Golden Circle sightseeing route and thus makes for the perfect detour for those on visiting these landmarks.
Kerid and the Golden Circle
The Golden Circle is Iceland’s most popular tourist route. 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.

There are several tour operators who offer trips to the Golden Circle. Many of those define their tours from 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, providing visitors with two routes by which they can return to Reykjavík.
If travelling to Kerið crater alone, please be aware that there is a small entrance fee, 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 Kerid
Kerið is approximately three thousand years old, making it roughly 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 be found in nearby, 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 why the lake is so vividly coloured is that of the minerals from the rocks, seeping into and dyeing the water the aquamarine colour for which it is renowned.

Haukadalur is a geothermal valley in South Iceland on the popular Golden Circle route.
Lying to the north of Lake Laugarvatn, it is home to hot springs, fumaroles, mud pots and geysers, including the famous Great Geysir and the active Strokkur. The area is noted for the vivid colouration of its surrounding hills, caused by elements deep in the earth being brought to the surface by the geothermal activity.
History of Haukadalur
Haukadalur has been mentioned in historic writings as far back as 1294, in which its geysers were described following an earthquake that activated them. Since the 18th Century, it has been drawing visitors to the island including two different Kings of Denmark in 1907 and 1922.
Throughout the 20th Century, images of the Great Geysir erupting at Haukadular began to symbolise Iceland. It’s activity, however, was unreliable, so unnatural efforts were made to stimulate it more regularly, such as lowering the water table in 1935 and pumping soap into it 1981.
These, however, limited the geyser’s long-term activity, so that it rarely goes off today, although, in the early 2000s, it did have a period where it was spouting water over 140 metres (459 ft) high. Even so, the geyser Strokkur is still very active, erupting to heights of 30 metres (98 ft) every five to ten minutes.
Today, most of the near-two million visitors to Iceland will see Haukadalur Valley on their travels.
Surroundings of Haukadalur
Haukadalur Valley is located about an hour and a half’s drive inland from Reykjavík, thus making many sites of the South and West easily accessible. The most notable of these are the other points on the Golden Circle: Gullfoss Waterfall (about five minutes away) and Þingvellir National Park (about forty minutes away).
It is also, however, within an easy driving distance of Flúðir, home of the Secret Lagoon, the Kjölur Highland Road, which leads into Iceland’s interior, Sólheimar eco-village, and Faxi Waterfall.
