Silfra and the Golden Circle | Snorkelling and Sightseeing
Admire the incredible sites of the Golden Circle, and see one of them in an exhilarating and unique new way with a snorkelling adventure in Silfra. This tour is perfect for those who want to see Iceland’s most famous places, but don’t want to miss out on any excitement.
You will be picked up in the morning and head straight towards your snorkel; nothing, after all, will wake you up like a plunge into Icelandic spring water.
Þingvellir, where Silfra is located, is within the rift valley between the North American and Eurasian tectonic plates, which are visible as soon as you enter the park. The geology and surrounding nature are breathtaking, and you will have your opportunity to explore them later in the day.
First, however, you will reach Silfra and get into your snorkelling gear and you can choose whether you snorkel in a wetsuit or drysuit.
When you enter the ravine, you will be instantly mesmerised by its incredible beauty. Not only is it a dramatic gorge, up to 63 metres deep, but it is a freshwater spring, with some of the clearest naturally occurring water in the world; the visibility exceeds a hundred metres. The sights, therefore, are unbelievable and will take your mind from the cold instantly.
Once you have marvelled over this wonder, you will exit the water, get into your dry clothes, and start exploring Þingvellir. This park is not only famed for its geology but also its fascinating history. It was here, after all, that early Vikings formed a representative parliament in 930 AD, which still continues to this day. This makes Þingvellir the original site of the world’s longest running parliament and a UNESCO World Heritage Site.
Following your walk through this area, you will head to the geothermal valley Haukadalur, home to hot springs, steaming vents, and two geysers. The first of these was the first described in European literature and gave all others their name: Geysir itself. The second is Strokkur, which, unlike its neighbour, is incredibly active, erupting every ten minutes or so to heights of up to forty metres.
Finally, you will head to Iceland’s most famous waterfall, Gullfoss. This majestic natural feature tumbles in two tiers into a beautiful canyon, and there are several viewing platforms to admire it from. One of these sits just feet away from where the water is falling.
Once the Golden Circle is complete, you will return to Reykjavík. This tour is sure to leave you in awe; not only will you have seen some of Iceland’s most incredible landmarks, but you'll also have seen one from underwater.
Do not hesitate to jump on this tour. Plunge into Silfra's depths, and explore the famed Golden Circle. Check booking availability by choosing a date.

The Golden Circle is a 300 km route to the 3 most popular natural attractions in Iceland. The Golden Circle consists of Geysir, Gullfoss and Thingvellir.
See this for Golden circle tours.
Geysir is a geyser that gives its name to hot springs all over the world. But although Geysir itself is not active anymore the area features spectacular hot springs such as the powerful Strokkur (spouting a vast amount of water every 10 minutes, regularly about 15-20 meters into the air), Smidur and Litli-Strokkur.
The 'Golden Waterfall', is the second part of the Golden Circle, and one of the most beautiful and powerful waterfalls in Iceland, plummeting 32 meters into the river gorge of the popular rafting river Hvita. It is Iocated about 10 km from Geysir.
Thingvellir national park
The largest attraction of the Golden Circle is Thingvellir National Park. The Icelandic parliament was founded there in 930 and remained until the year 1798.
Today it is a UNESCO World Heritage Site and one of the most important places to visit in Iceland, not just for its historical and cultural values, but for also its magnificent landscape.
Thingvellir is surrounded by a beautiful mountain and volcano range and is the site of a rift valley, where the tectonic plates meet, marking the crest of the Mid-Atlantic ridge.
Of particular note at Thingvellir are the magnificent Almannagja gorge, and the beautiful lake Thingvallavatn, the largest lake in Iceland. The popular Gjabakkahellir lava cave is also in the area.
The fissure Silfra is located by Thingvallavatn, Iceland's largest lake, and is famous for its clear waters and popular for diving and snorkeling, as you can literally swim between continents.Geysir,
Geysir is a famous hot spring in Haukadalur valley in South Iceland. Part of the ‘Golden Circle', Geysir gives its name to hot springs all over the world.
Though Geysir itself is hardly active anymore, the area features spectacular hot springs such as the powerful Strokkur, which spouts a vast amount of water every 10 minutes, around 15-20 meters into the air, Smidur and Litli-Strokkur.
North of Geysir are fumaroles, i.e. unlike the hot springs that emit hot water, only steam and gas emanate from these. You may be able to observe bright yellow stains at the fumaroles, this is native sulphur, which crystallizes from the steam. At the southern part of the geothermal area, called Thykkuhverir, you‘ll find various mud pots. Such mud pots are actually fumaroles that boil up through surface water/groundwater and may become steaming fumaroles during dry spells, rather than the usual boiling mud pots.
About 2 km from Geysir is an old preserved natural pool called Kúalaug. One can bathe in it and it has room for 3-5 people at a time, but care should be taken, as the area around the pool is very delicate. The temperature is 39-43°C, depending on how 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.
In Haukadalur there has also been tree planting in recent times and today the forest Haukadalsskógur is one of the largest in South Iceland. Aspen, various types of pine, and other plants have been tried out there and experiments and research continue. We also recommend visiting the tree museum, built in the memory of forester Gunnar Freysteinsson. There are good paths and roads in the forest and the wood is specially designed to accommodate wheelchairs.
Haukadalur has been a church site since ancient time. The current wooden church was last rebuilt in 1938 but the variety and appearance of the church dates back to 1842, making it one of the oldest of its kind in Iceland.
Haukadalur is indeed a historical place. It was settled during the age of settlement and scholar Ari “The Wise“ Thorgilsson grew up there. The first pastoral school in Iceland was also built there.
For accommodation, Hotel Gullfoss is about 7 km from the Geysir area, and closer still is the Hotel Geysir.Gullfoss,
Gullfoss (translated to ‘Golden Falls’) is one of Iceland’s most iconic and beloved waterfalls, found on the Hvítá river canyon in south Iceland. The water in Hvítá river travels from the glacier Langjökull, finally cascading 32m down Gullfoss’ two stages in a dramatic display of nature’s raw power.
Because of the waterfall’s two stages, Gullfoss should actually be thought of as two separate waterfalls. The first, shorter stage of the waterfall is 11m, whilst the second stage is 21m. The canyon walls on both sides of the waterfall reach heights of up to 70m, descending into the 2.5km long Gullfossgjúfur canyon (geologists indicate that this canyon was formed by glacial outbursts at the beginning of the last age.)
In the summer, approximately 140 cubic metres of water surges down the waterfall every second, whilst in winter that number drops to around 109 cubic metres. With such energy, visitor’s should not be surprised to find themselves drenched by the waterfall’s mighty spray-off.
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 known only as Howells 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 Howells the land, inadvertently beginning the first chapter of Icelandic environmentalism.
It was Tómas’ daughter, Sigríður Tómasdóttir, who would lead the charge. Having grown up on her father’s sheep farm, she sought to get the lease 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 if only to keep the trial moving. Circumstances became so difficult that Sigríður threatened to throw herself into the waterfall if any construction began.
Thankfully, in 1929, 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. Her contribution is forever marked in stone; a plaque detailing her plight sits at the top of Gullfoss.
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,
Þingvellir is one of the most important sites to visit in Iceland for its landscape, history and cultural value.
The Icelandic parliament was founded in Þingvellir in 930 and remained there for centuries. Þingvellir is surrounded by a beautiful mountain range and is the site of a rift valley, marking the crest of the Mid-Atlantic range. Today it is a natural park, listed as a World Heritage Site by UNESCO and considered a vital part of the ‘Golden triangle’ (with Geysir and Gullfoss). Of particular note is the magnificent gorge Almannagjá, which marks the eastern boundary of the North American plate and into which the beautiful waterfall Öxarárfoss falls.
Other notable attractions within the park include the beautiful lake Þingvallavatn, the largest lake in Iceland, the Silfra fissure, one of the world's top dives, Þingvallakirkja Church and Gjábakkahellir, one of Iceland's most interesting lava tubes.Strokkur,
Strokkur (Icelandic for "churn") is one of the most famous hot springs in Iceland and belongs to the famous Golden Circle.
Strokkur is a fountain geyser in the Geysir geothermal area in the southwest part of the country, east of Reykjavik. Strokkur is a powerful hot spring and an impressive sight. It erupts about every 4–8 minutes and spouts water to a height of 15 – 20 m, sometimes up to 40 m.Silfra
Silfra is a fissure filled with fresh springwater 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 when they do, tear open fissures in the land between them.
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 like is done on this tour. 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.
