丝浮拉浮潜＋黄金圈观光一日游

绵延300公里的黄金圈是冰岛最热门的旅游路线，盖歇尔间歇泉地热区(Geysir)、黄金瀑布(Gullfoss)与辛格维利尔国家公园(Þingvellir)三大景点都是冰岛旅行的必游景点。

黄金圈景区交通便利，从首都雷克雅未克出发一日之内即可往返；租车自驾和参加旅行团都是绝佳的旅行选择，一些旅行团还将黄金圈自然观光与浮潜、雪地摩托、直升机、午夜阳光等特色旅行项目结合，升级黄金圈旅行体验。

黄金圈是冰岛最经典的旅行路线，三大自然景点尽显冰岛地质的神奇瑰丽与冰岛文化的恢弘迷人。

盖歇尔间歇泉地热区

盖歇尔间歇泉地热区位于Haukadalur山谷内。间歇泉这一地热奇观的英文学名“geyser”就源自这一地区的盖歇尔(Geysir)。

如今盖歇尔已几乎不再喷发，取而代之的是活跃的史托克间歇泉(Strokkur)；每隔5～10分钟，史托克便喷发出40余米的沸腾水柱，地心深处的澎湃力量也由此涌出地表。

地热区还遍布着蒸汽孔、沸泥潭、地热喷泉等地热奇观，除了盖歇尔与史托克外，这里还分布有Smiður与Litli-Strokkur两座小型间歇泉。盖歇尔景区设施齐全，设有酒店、餐厅、咖啡厅与旅行纪念品商店。

黄金瀑布

黄金瀑布是冰岛最壮丽的瀑布之一，也是冰岛最大的断层瀑布。瀑布高达32米，分为两层汇入峡谷；发源自Hvítá“白河”的黄金瀑布水流极为丰沛，Hvítá也是冰岛最受欢迎的漂流地点之一。黄金瀑布距离盖歇尔间歇泉地热区仅有10分钟车程，也是黄金圈三大景点中距离首都雷克雅未克最远的一处。

20世纪初时，英国投资者预备在黄金瀑布筑坝，利用瀑布的强大水能发电。虽然已拿到一纸租约，但瀑布土地所有者的女儿Sigríður Tómasdóttir始终与其抗争，竭尽全力保护这片生养自己的美丽国土。Sigríður曾数度步行200公里，往返于雷克雅未克与黄金瀑布之间，与律师商讨对策，最终终使投资商放弃了修建水电站的计划。

Sigríður终于成功，冰岛也从此禁止外国投资商染指瀑布；Sigríður被誉为冰岛第一位环境主义者，也位列冰岛历史上最重要的人物之一。

辛格维利尔国家公园

辛格维利尔国家公园是黄金圈景区的最后一处景点。公元930年，冰岛议会于辛格维利尔成立，直至1798年才搬迁至雷克雅未克。冰岛议会也是世界上运行时间最长的民主议会。

辛格维利尔国家公园被联合国教科文组织认证为世界文化遗产，也是冰岛最具历史文化价值的人文景点之一。与此同时，辛格维利尔恢弘的地理地质与维京历史亦相映成趣。北美与亚欧两大地质板块于此交界，大西洋中脊横贯其间，板块分界的大裂谷与火山地貌无比震撼。

丝浮拉大裂缝(Silfra)即形成于板块地质运动，裂缝中注满了纯净剔透的冰川融水，水下能见度可达100米以上，五光十色的水下世界仿如梦幻，因此丝浮拉大裂缝也成为了举世闻名的浮潜与潜水地点。丝浮拉水温常年维持在2°C，因此多数游客会选择参加干衣浮潜，收获在两大板块之间潜水畅游的非凡体验。

在Almannagjá峡谷，游客可以触摸北美板块的粗糙边缘；在冰岛最大湖泊议会湖(Þingvallavatn)，游客则可以领略粗犷火山地貌的静美一面。

黄金圈景区小众景点

黄金圈景区位于冰岛西南部，与许多小众景点相距不远。Flúðir小镇的秘密温泉与Laugarvatn地区的Fontana温泉都是体验冰岛地热温泉的完美去处；经由朗格冰川(Langjökull)的人造冰川隧道，游客可以深入探秘冰川内部构造；在索尔黑马生态村(Sólheimar)，游客可以体验别样的生活艺术；Kerið火山口湖的迷人景色也同样不容错过。

盖歇尔地热区(Geysir)是举世闻名的间歇泉喷发区，坐落于冰岛西南岸的Haukadalur山谷中。

辛格维利尔国家公园(Þingvellir)、黄金瀑布(Gullfoss)与盖歇尔地热区共同组成了冰岛最热门的黄金圈景区。

盖歇尔间歇泉地理特征

盖歇尔间歇泉的喷发强度曾为所有间歇泉之首，如今却鲜少喷发，而Haukadalur山谷中还分布着多座间歇泉，其中就包括最为活跃的史托克间歇泉(Strokkur)，以及规模更小的Smiður与Litli-Strokkur。

史托克间歇泉是世界最活跃的间歇泉之一，每隔5～10分钟就喷发一道沸腾的水柱，高达20～40米，场面颇为壮观。许多游客都会准备好相机，拍下史托克陡然喷发的壮丽一瞬。

盖歇尔间歇泉规模更大，但如今的喷发频率极低，间隔数年方能喷发一次；而盖歇尔常常是不喷则已，一喷惊人，水柱高度可达70余米。

盖歇尔间歇泉以北分布着许多蒸汽孔，散发的滚滚蒸汽在凉爽的冰岛空气中徐徐飘动，别是一番外星般的奇妙风光。蒸汽孔周围的土地则被硫磺等矿物漆染，大地呈现出斑斓的地热色彩交织。

山谷南部的Þykkuhverir沸泥潭则仿佛是童话故事中巫婆的大锅，如锅炉般一刻不停地冒泡。沸泥潭实际上也是蒸汽孔的一种，泥浆干涸后便成为普通蒸汽孔。

盖歇尔间歇泉周边小众景点

Kúalaug天然温泉与盖歇尔间歇泉相距2公里，温泉最多可容纳3～5人，水温在39～43°C之间。在体验温泉时，要格外注意保护该地的脆弱生态。温泉底部为土壤，因此水中混有些许泥浆；温泉底部生长有湿滑的水藻，游客需注意安全，以防跌倒。

Haukadalur山谷虽为地热区，但经过不断的植树造林，这里也生长起一片颇为茂盛的森林。Haukadalsskógur是冰岛南岸的最大森林之一，游客可以经由林中小径漫步，参观林中植被，以及为纪念林务员Gunnar Freysteinsson而修建的树木博物馆。

盖歇尔地热区的文化历史

自冰岛有人定居开始，Haukadalur山谷就一直有人居住，人们还曾在此修建教堂。冰岛11世纪的著名历史学家Ari Þorgilsson就成长于此；冰岛第一所牧师学校就建立于此。Haukadalskirkja教堂为木质教堂，其建筑风格可追溯至1842年，展现着冰岛工业化进程开始前的建筑风情。

Hotel Gullfoss酒店距盖歇尔地区约7公里；Hotel Geysir酒店则与景区仅一路之隔，景区设施齐全，设有咖啡厅以及纪念品商店。

黄金瀑布(Gullfoss)又译为居德瀑布、古佛斯瀑布，发源自冰岛西南部的Hvítá白河，是冰岛最壮丽、最著名的瀑布之一。

Hvítá白河发源自朗格冰川(Langjökull)；河流跌落32米，历经两级阶梯，最终汇入峡谷，塑造了黄金瀑布这座壮观的双层瀑布。黄金瀑布与辛格维利尔国家公园、盖歇尔间歇泉地热区共同组成了冰岛最受欢迎的旅行景区——黄金圈。

黄金瀑布分为两层，我们也可将其视为两座瀑布。第一层也即较短的一层瀑布高约11米，第二层瀑布高约21米。瀑布两侧的峡谷岩壁耸拔70余米，一线倾斜后又与开阔的Gullfossgljúfur峡谷相接。据地质学家推算，峡谷的形成历史可追溯至末次冰期的冰川洪流。

黄金瀑布夏季每秒钟的水量可达140立方米，冬季时的水量约为109立方米/秒。丰沛而湍急的水流使得瀑布气势磅礴，令每一位身临其境的游客颇感震撼。

黄金瀑布是冰岛黄金圈景区的三大景点之一，许多旅行团也从黄金瀑布集合出发，其中最受欢迎的要属在朗格冰川进行的雪地摩托与冰川隧道旅行团。

黄金瀑布的历史

正因蕴含了丰富的水能，黄金瀑布的磅礴风光才如此引人入胜。黄金瀑布的能量却也引起了外国投资者的兴趣。1907年，一位名为Howell的英国商人就曾设想在黄金瀑布建立水电站。Howell出价购买黄金瀑布，而当时黄金瀑布地段的所有者Tómas Tómasson严辞拒绝，说出了“我不会出卖我的朋友！”这句名言。于是Howell转而选择租用这片土地，以实现修建水电站的计划。

保卫瀑布的重任落在了Tómas的女儿Sigríður Tómasdóttir身上，她雇用了一位律师，努力以法律的方式捍卫瀑布的自然生态。Sigríður数次往返于官员所在的雷克雅未克与家乡黄金瀑布之间，几度徒步走过100公里的路程，与各方斡旋。为了阻止人们破坏瀑布，Sigríður甚至威胁跳入瀑布，以其生命誓死抵抗。

Sigríður的抗争终获成功。1929年，Howell撤回其租约，放弃了修建水电站的计划，黄金瀑布也得以保持其原始却美丽的自然生态。Sigríður也常被赞誉为冰岛第一位环境保护主义者，被载入冰岛史册。黄金瀑布旁的石碑上就记载了她的光辉事迹。Sigríður的律师Sveinn Björnsson也是冰岛历史中的重要人物：1944年冰岛建国后的首位总统。

黄金瀑布景区的餐饮

在黄金瀑布咖啡厅(Gullfoss Cafe)中，游客可以品尝冰岛特色美食；在黄金瀑布景区的商店中，游客也可以将冰岛特色旅行纪念品带回家。

辛格维利尔国家公园，又译辛格韦德利国家公园，是冰岛大陆上唯一被联合国教科文组织认证为世界文化遗产的地点。它和盖歇尔间歇泉、黄金瀑布，组成了著名的黄金圈旅游线路。公园南侧是冰岛最大的湖泊－辛格瓦德拉湖（Þingvallavatn）。

地理

辛格维利尔的地理地质特性在世界上独一无二。欧亚大陆板块与美洲大陆板块在此相会，且暴露在海平面之上。全世界只能在冰岛看到两大地质板块在海平面之上相会的地质奇观。

游览时，建议从美洲大陆板块一侧开始观光，在这里的信息牌上可以阅读到这个地区的更多有趣信息和历史，之后可以再走入其下的山谷。

历史

辛格维利尔在冰岛语中的意思为“议会土地”，从它的名字就不难猜出它的历史。在这里，世界上的第一个民主议会诞生－公园930年，维京人选址在此，创立了冰岛的议会。

民主议会也许和维京人喜欢战争掠杀的名声背道而驰，但当时的30多个氏族急需在恶劣的新环境中求得生存与繁荣。第一次集会的空前成功，让议会得以保留。每年，人们聚集在此，解决争端、审判罪犯、制定让所有人都能受益的法律。

冰岛联邦就此诞生，让冰岛人在成为挪威王国的选民前就获得了独立与自由。冰岛在辛格维利尔的年度议会一直延续到了1798年。

丹麦王国取消了冰岛的议会，直至1845年，冰岛的议会在雷克雅未克重生。

辛格维利尔在冰岛历史上的另一个重要角色与信仰有关，公园1000年，挪威入侵冰岛，冰岛人在辛格维利尔舍弃异教信仰、北欧众神，转而投信基督教。

冰岛的法律演讲人、议长Þorgeir Ljósvetningagoði是冰岛的这场信仰危机中起到了决定性的作用，他考虑了一天一夜，才回到这里宣布了他的决定。

为了见证冰岛信仰的转变，Þorgeir将北欧众神的神像抛入北部的众神瀑布－Goðafoss，瀑布正得名于此。

丝浮拉裂缝

辛格维利尔是冰岛最受欢迎的自然景点之一，而除了上述的自然、历史原因，它还有另一大独特的景观－丝浮拉裂缝（Silfra，又译史费拉裂缝）。丝浮拉裂缝流淌着冰川水，是世界上排名前十的浮潜、潜水地。

丝浮拉在冰岛语中意为“银”，是公园内的一个水下峡谷，能见度高达100余米，温度常年保持在零上。世界各地的人们在这里穿上潜水衣，去水下享受完美的失重感，以及遨游在两大地质板块间的难得体验。

Strokkur is Iceland’s most visited active geyser. One of the three major attractions on the world-famous Golden Circle sightseeing route, it is usually visited alongside Gullfoss Waterfall and Þingvellir National Park.

Strokkur is found in the Geysir Geothermal Area, titled after the Great Geysir, which lent its name to all others across the world. It is the greatest active geyser on site; Geysir itself is in a period of inactivity. Strokkur erupts more regularly than Geysir ever did, blasting water to heights of around fifteen to twenty metres every five to ten minutes, although it is known to reach up to forty metres. 

Strokkur and Haukadalur Valley

Strokkur is the primary feature of the Haukadalur valley and the main reason why it is one of the most visited sites in the country. While Geysir will very occasionally still erupt to enormous heights, it is nowhere near reliable enough to justify the area’s popularity.

Haukadalur valley, however, has many other features that make it worth a visit. The natural beauty of the area is shaped by the forces of the earth; fumaroles, hot-springs, mud-pits and other little geysers are littered around, and the ground itself is dyed vividly by elements such as sulfur (yellow), copper (green) and iron (red).

Opposite the main geothermal area in Haukadalur Valley is a restaurant, cafe, hotel and luxury gift shop.

Science behind Strokkur

Active geysers like Strokkur are rare around the world, due to the fact that many conditions must be met for them to form. They are thus only found in certain parts of highly geothermal areas.

The first condition that is necessary is an intense heat source; magma must be close enough to the surface of the earth for the rocks to be hot enough to boil water. Considering that Iceland is located on top of the rift valley between the North American and Eurasian tectonic plates, this condition is met throughout most of the county.

Secondly, you will need a source of flowing underground water. In the case of Strokkur, this comes from the second largest glacier in the country, Langjökull. Meltwater from the glacier sinks into the surrounding porous lava rock, and travels underground in all directions.

Evidence of this flowing water can be found in Þingvellir National Park, where there are many freshwater springs flowing straight from the earth.

Finally, you need a complex plumbing system that allows a geyser to erupt, rather than just steam from the ground like a fumarole. Above the intense heat source, there must be space for the flowing water to gather like a reservoir. From this basin, there must be a vent to the surface. This vent must be lined with silica so that the boiling, rising water cannot escape before the eruption.

Environmental Issues with Strokkur

One of the main reasons that Geysir entered a period of inactivity was due to the fact soap used to be pumped into the vents to make the eruptions more dramatic; it damaged the structure of the vent and prevented water building up. Strokkur, therefore, is guarded against all interference, with chains keeping visitors a good distance away.

Unfortunately, however, there have been incidents where people have meddled with its natural state. For example, an artist called Marco Evaristti once poured food colouring into it to make the eruption pink. He defended himself by claiming that nature was open to artists to utiltise and the fact the colouring was all-natural, but he became a pariah amongst many Icelanders, and was arrested and fined (though never paid it).

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.
