参加这个团，您将有两次在丝浮拉裂缝（Silfra）潜水的机会，探索深邃的蓝色世界。丝浮拉大裂缝坐落于辛格维利尔国家公园（Þingvellir National Park），2004年时辛格维利尔国家公园被联合国教科文组织评为世界文化遗产，这里对冰岛人而言有着重大的历史意义——冰岛人在此建立了世界上最古老的、仍在运行的议会。丝浮拉大裂缝位于亚欧板块和美洲板块之间的裂谷顶端，地理位置十分特殊。
如果您住在雷克雅未克，我们将到您下榻的酒店接您（限雷克雅未克市区酒店或旅舍），然后在雷克雅未克准备潜水器材、挑选合适的潜水服并为您详细讲解安全规则和当日的具体行程安排。随后我们会向辛格维利尔国家公园进发，车程约40分钟。在丝浮拉的停车场，我们将为接下来的两次潜水做好准备。旅行团结束后我们会将您送回酒店，时长（包括大巴时间）共约6小时。您也可以不选择接团服务，直接与我们在辛格维利尔国家公园信息中心(Þingvellir Information Center)集合。

Thingvellir is one of the most important sites to visit in Iceland for its landscape, history and cultural value.
The Icelandic parliament was founded in Thingvellir in 930 and remained there for centuries.Thingvellir 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 Almannagja, which marks the eastern boundary of the north American plate and into which the beautiful waterfall Oxararfoss falls.
Other notable attractions within the park include the beautiful lake Thingvallavatn, the largest lake in Iceland, the Silfra fissure, one of the world's top dives, and Gjabakkahellir, one of Iceland's most interesting lava tubes.
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.
