杰古沙龙冰河湖（Jokulsarlon）水陆两栖船游

冰岛南岸是冰岛最受欢迎、最热门的旅游景区之一，也是冰岛明星必游景点最为集中的地区。

黄金圈、杰古沙龙冰河湖(Jökulsárlón)、斯科加瀑布(Skógafoss)、塞里雅兰瀑布(Seljalandsfoss)、斯卡夫塔山等游客们耳熟能详、举世闻名的自然景点都位于冰岛南岸地区。

概括而论，冰岛南部可以分为两个部分：西部的低地平原地区以及东部地区。

冰岛南部的低地地区

冰岛南部的低地地区始自Hellisheiði地热区，终至埃亚菲亚德拉冰川(Eyjafjallajökull)，长达100公里。这一地区分布着平坦且肥沃的耕地，是许多冰岛马和冰岛羊的家园。

从地质方面来看，这一地区非常“年轻”；低地地貌形成于冰河时期，由火山爆发泄出的岩浆流塑造。至今这片地区仍然保存着不少活跃的火山系统，如埃亚菲亚德拉冰川火山、海克拉火山(Hekla)等等。

冰岛最著名的旅游路线黄金圈也属于这片南部低地地区。黄金圈的三大景点包括位于两大地质板块交界的世界遗产辛格维利尔国家公园(Þingvellir)、地热运动活跃的盖歇尔间歇泉地热区(Geysir)与冰岛最大的断层瀑布黄金瀑布(Gullfoss)。

值得一提的是，位于北美与欧亚板块的交界处的辛格维利尔国家公园不仅是地理的瑰宝，还是冰岛主陆唯一一处联合国教科文组织认定的世界文化遗产；世界首个民主议会Alþingi即诞生于此，这也是冰岛乃至世界范围的珍贵历史遗产。

这一地区的活跃地热运动也直接塑造了许多特色地貌，例如1975年韦斯特曼群岛(Westman Islands，也称西人群岛)的火山爆发就促成了一个崭新岛屿的形成。

与大多数早期冰岛聚落不同，冰岛南部的低地地区少有渔业城镇，仅有唯一一个重要的港口城镇：Þorlákshöfn；前往韦斯特曼群岛的渡轮也从Þorlákshöfn出发。

其他城镇则主要位于内陆地区，包括一号环岛公路上的塞尔福斯(Selfoss)、惠拉盖尔济(Hveragerði，“温泉小镇”)、海德拉(Hella)以及科沃尔斯瓦特鲁(Hvolsvöllur)等。

冰岛南部的低地地区也孕育了迷人的文化。冰岛第一位主教的定居地斯考尔霍特(Skálholt)就位于这片地区，而恢弘的《尼雅尔萨迦》的文学情节也在这一地区展开。

游客在这一地区也可以参加如骑冰岛马、钓鱼、徒步、浮潜、皮划艇等特色户外活动。

冰岛南部的东部地区

这一地区大概覆盖了卡特拉火山(Katla)/米尔达斯冰川(Mýrdalsjökull)至杰古沙龙冰河湖一带，以数目众多的火山、冰川与迷人的高地景色闻名。

与冰岛南部的低地地区一样，这一地区的地貌形成也同样受到火山爆发的深刻影响，却呈现出截然不同的地质景观。游客将在这里发现黑沙滩、悬崖石壁、玄武岩石、瀑布、冰川、火山等极具冰岛特色的壮丽地貌。

这一地区的冰川河也衍生出许多瀑布，其中就包括著名的斯科加瀑布与塞里雅兰瀑布。

索尔黑马冰川(Sólheimajokull)也位于这一地区。索尔黑马是米达冰川的一条冰舌，游客可以跟随专业向导，参加冰川徒步旅行团，以双脚丈量冰川的磅礴。在斯科加镇(Skógar)，游客可以参观民俗博物馆，了解冰岛的发展历程。Fímmvörðuháls等著名徒步路线等则沟通了海岸地区与内陆高地地区。

冰岛最南小镇维克镇(Vík)也坐落于此，集聚于小镇周围的雷尼斯黑沙滩(Reynisfjara)、迪霍拉里岬角(Dýrholaey)、Reynisdrangar岩柱都是在冰岛南岸之行中不容错过的美景。

沿一号公路继续东行，游客将抵达斯卡夫塔山自然保护区(Skaftafell)。斯卡夫塔山是冰岛最大国家公园——瓦特纳冰川国家公园(Vatnajökull)的一部分。

被誉为“冰岛自然王冠上最耀眼的宝石”的杰古沙龙冰河湖接近冰岛东部与南部的交界，冰河湖对面布满碎冰的“钻石冰沙滩”也是这一地区最为迷人的自然宝藏之一。

冰岛南岸的杰古沙龙冰河湖(Jökulsárlón)是冰岛最著名的冰泻湖，位于冰岛一号环岛公路沿途，处于斯卡夫塔山自然保护区(Skaftafell)和霍芬镇(Höfn)之间，是冰岛旅行最热门的必游自然景点之一。

地理

杰古沙龙冰河湖由Breiðamerkurjökull冰舌的冰川融水滋养，而这条冰舌则发源自欧洲最大冰川——瓦特纳冰原(Vatnajökull)。

一年四季无分昼夜，冰湖内始终漂浮着许多巨型冰块，其中的一些甚至与楼房等高。

浮冰的巨型体积引人瞩目，而纯白与冰蓝混合的冰块颜色、掺杂火山灰的冰块纹理。也都令造访冰河湖的游人颇感震撼。

浮冰跟随水流渐渐漂流入海，进入广袤的大西洋，而有些冰块则会被冲刷到Breiðamerkursandur黑沙滩上；这片聚集了无数如钻石般闪耀的碎冰的沙滩，也因此被冠上了“钻石冰沙滩”的名号。

虽然杰古沙龙冰河湖只是近代才出现的自然景观，如今却已经成为冰岛最深的湖泊。目前杰古沙龙冰河湖深约248米，面积约为18平方公里。随着冰川不断消融退却，在不久的将来，杰古沙龙冰河湖也会逐步演变成冰岛最大的湖泊。

历史

杰古沙龙冰河湖并非自移民定居时代就一直存在的自然景观，而是在1935年才开始慢慢形成的。自20世纪以来，冰岛的平均气温逐年升高。1920年，Breiðamerkurjökull冰舌开始迅速融化退却，其融水也逐步填满了冰川脚下的大片空地，形成了一片冰河湖。

杰古沙龙冰河湖的面积仍在持续扩张，现在的面积已经比1975年扩大了两倍以上。随着扩张持续，杰古沙龙冰河湖最终会变为峡湾。

冰岛冰川的消融一直都是严峻的自然灾难，但无意中形成的冰河湖也称得上是一个短暂的“美丽错误”。

世界各地的电影导演早已发现了杰古沙龙冰河湖的绝世之美。詹姆士·邦德系列电影《007之雷霆杀机》(1985年)、《择日而亡》(2002年)、《蝙蝠侠：侠影之谜》(2005年)等电影大片都曾在此取景拍摄，将冰河湖之美搬上了大荧幕。

2017年，杰古沙龙冰河湖正式被纳入冰岛瓦特纳冰川国家公园，成为受冰岛法律保护的自然景点。

野生生态

潮汐为杰古沙龙冰河湖带来了众多的鲱鱼和毛鳞鱼，也因此吸引了许多野生动物来此安家，聚居觅食。

夏季时，许多北极燕鸥会在此筑巢繁衍。北极燕鸥是攻击力极强的鸟类，它们会奋不顾身地攻击接近其鸟蛋的生物。如果在夏天到访冰河湖，一定不要走近北极燕鸥的巢穴，以防被攻击。此外贼鸥也会在此筑巢孵蛋、繁衍后代。

野生海豹则一年四季都以冰河湖为家。无论任何季节到访杰古沙龙冰河湖，游人都有机会看到海豹们在巨型浮冰之间戏水嬉闹、慵懒躺卧的可爱景象。杰古沙龙冰河湖不但为海豹们提供了丰富的食物，也成为了它们避开冰岛东南部海域的虎鲸的避风港。

Vatnajökull glacier is the largest glacier in Europe, covering 8% of Iceland’s landmass.

It is the central feature of the Vatnajökull National park, found in the south west of Iceland, a popular spot for activities like glacier hiking from Skaftafell, boat tours in the Jökulsárlón glacier lagoon, and ice caving tours between November and March.

Facts about Vatnajokull

Vatnajökull has a surface area of approximately 8,100 square kilometres (3127 square miles); though it is rapidly shrinking due to climate change, its recession is not quite as advanced as at other glaciers, such as Langjökull and Mýrdalsjökull. In parts, it is a kilometre deep (over three thousand feet), and its average thickness is around half of that.

Vatnajökull also holds the tallest peak in Iceland beneath its ice; Hvannadalshnjúkur is 2,200 metres tall (7,218 feet). It also conceals some of the most active volcanoes in the country, the most notable being Grímsvötn, Öræfajökull and Bárðarbunga.

Volcanic activity in the region has occurred on and off throughout the centuries, and many geologists believe that several eruptions are overdue. If their calculations are correct, it would mean significant volcanic activity for Vatnajökull over the scope of the next half-century.

Depending on winds, this could result in worldwide consequences in terms of air-travel, agriculture and the general climate.

The glacier boasts over 30 outlet glaciers, which are channels of ice that flow out of ice caps but remain constrained on the sides of the valley. The major outlet glaciers of Vatnajökull include Dyngjujökull in the north, Breiðamerkurjökull, and Skeiðarárjökull to the south. To the west, one can find the outlet glaciers Síðujökull, Skaftárjökull and Tungnaárjökull.

Numerous rivers run out of Vatnajökull, making up some of the greatest glacial rivers in Iceland. The most notable are:

• Tungnaá (west)

• Köldukvísl (west)

• Þjórsá (west)

• Jökulsá á Fjöllum (north)

• Skjálfandafljót (north)

• Jökulsá á Brú (northeast)

• Jökulsá í Fljótsdal (northeast)

• Jökulsá í Lóni (south)

• Hornafjarðarfljót (south)

• Jökulsá á Breiðamerkursandi (south)

• Skeiðará (south)

• Núpsvötn (south)

• Hverfisfljót (south)

• Skaftá (south)

Vatnajokull National Park

Vatnajökull National Park was established in June 2008 and has slowly grown to include more and more areas. The park now covers an area of 14,141 square kilometres (5,460 square miles), 14% of the country. It is the second largest national park in Europe.

Rivers divide the highland plateau to the north of the park. The volcanic table mountain Herðubreið towers over this particular region, along with volcanoes Askja, Snæfell and Kverkfjöll.

The canyon Jökulsárgljúfur was carved out by glacial floods centuries ago. At the upper end of the canyon, you'll find Dettifoss, the most powerful waterfall in Europe. Further north, the horseshoe-shaped canyon Ásbyrgi is believed to have formed when Óðinn's eight-legged horse, Sleipnir, stepped his foot down from the heavens.

East around Snæfell, one can find wetlands and ranges, home to roaming herds of wild reindeer and abundant birdlife. Steep mountain ridges make up the south side of Vatnajökull, where outlet glaciers crawl onto the lowlands. The sandy plains of Skeiðarársandur also lie to the south, and the glacial river Skeiðará runs through this vast desert.

One of Iceland's most visited landmarks in the National Park is the Jökulsárlón glacier lagoon, which sits at the base of the outlet glacier Breiðamerkurjökull. Here, large icebergs that have broken off the glacier float across a vast lake before ending up in the Atlantic Ocean, or washed ashore on the nearby Diamond Beach.

This is one of the best seal-watching spots in the country.

The Future of Vatnajokull

The volume of Vatnajökull reached its peak around 1930 but has since been in a steady process of decline. Because of rising levels of global temperature, Vatnajökull has on average lost about a metre (three feet) of its thickness annually over the past 15 years.

If temperature levels continue to rise, the glacier could be all but gone nearing the end of the next century, leaving only small ice caps on top of the highest mountain summits.  

Efforts are being made to prevent what some say is the inevitable, with reforestation projects going on all around the glacier, a proven method of cooling the area. Time will tell how successful they are.

Vatnajokull and Jokulsarlon in Popular Culture

The beauty of Vatnajökull National Park has not gone unnoticed by those in film or television. Many famous scenes have been shot here, starting with James Bond: A View to Kill in 1985. Other notable films with scenes here include Batman Begins, Lara Croft: Tomb Raider, and James Bond: Die Another Day.

Most famously, however, many places in Vatnajökull have been used in the HBO Series Game of Thrones, north of the Wall. The Wall itself is constructed with CGI using shots of the glacier.

Breiðamerkurjökull is the glacial tongue that extends from southern Vatnajökull and into the glacier lagoon Jökulsárlón, creating the icebergs that define this beautiful landmark.

Breiðamerkurjökull is constantly retreating, breaking and melting, causing the Jökulsárlón glacier lagoon to increase in size; it is less than a century old, but already the deepest lake in Iceland.

This glacier tongue provides the lagoon with all of its enormous icebergs, which perpetually break from off its tip and tumble into the waters. Here they float for about five years until they are small enough to make their way towards sea. When they finally do escape the lagoon, most join the countless smaller ice chunks that adorn the nearby Diamond Beach.

Breiðamerkurjökull is beset with enormous cracks and crevices, and since it's virtually impossible to tell exactly when the next big block of ice will break from it, people should admire this enormous glacier tongue from a great distance.

The South Coast of Iceland is the country's most visited sightseeing route, along with the Golden Circle.

This incredible shoreline stretches from the greater Reykjavík area in the west to the magnificent Jökulsárlón glacier lagoon in the east and is lined with countless natural wonders such as cascading waterfalls, volcanoes, black sand beaches and glaciers.

Geography, Nature & Wildlife

The South Coast is the most easily accessible part of the country’s southern region, found along the Route 1 highway (the Ring Road), which encircles Iceland. The area consists of a diverse lowland that transitions between, marshlands, bays, cultivated pastures, estuaries and black sand deserts.

Underneath the soil rests a vast lava field, known as Þjórsárhraun. Its edges reach several hundred metres offshore where the ocean waves crash upon them, thereby protecting the lowland from the invasion of the sea. This results in the South Coast being unusually lacking in the deep fjords that so distinctly characterise the rest of Iceland's shoreline.

The region boasts vibrant bird life during all seasons. Freshwater birds nest in the marshlands and around the estuaries, while seabirds flock around the cliffs of Reynisdrangar and Dyrhólaey, including the North Atlantic puffin between May and August. Some species stay throughout the harsh Icelandic winter, including the northern diver, the loom and various species of gulls and ducks.  

Seals are often found along the shore, particularly around the Jökulsárlón Glacier Lagoon and Diamond Beach. As with everywhere in Iceland, you should always keep an eye out to sea, as whales and dolphins reside all along its coastline.

Highlights of the South Coast

The South Coast offers an unprecedented array of natural wonders that draw thousands of visitors each day.

When driving the route from Reykjavík city, the first major features are the two great waterfalls of Seljalandsfoss and Skógafoss, which sit beneath the notorious subglacial volcano, Eyjafjallajökull. On clear days from these beautiful cascades, the Westman Islands can be seen across the ocean.

A little further down the route is the glacier Mýrdalsjökull, which covers one of Iceland’s most explosive volcanoes, Katla. Many glacier hikes are taken here upon the outlet of Sólheimajökull.

The aforementioned Dyrhólaey cliffs are next, home to many seabirds. Even if you come outside of puffin season, they are well worth a visit; jutting out to sea is an enormous rock arch of the same name, which you can marvel at from many angles.

Adjacent to the village of Vík is the famous black-sand beach, Reynisfjara, home to the rock pillars of Reynisdrangar, said to be two trolls frozen by the light of the sun. Though beautiful, this area is gaining notoriety for its dangerous sneaker waves, so visitors should be sure to stay well away from the edge of the water, even on a calm, still day.

There are no landmasses between Reynisfjara beach and the continent of Antarctica, so you can imagine how the waves can build momentum.

After passing through Vík, you will cross the glacial sand plain of Skeiðarársandur, before entering Vatnajökull National Park, home to the largest ice cap in Europe, Vatnajökull itself, dozens of glacial outlets and the magnificent Jökulsárlón glacier lagoon.

While almost all of these sites can be seen from Route 1, they make up a fraction of what the South Coast has to offer. The vast sand plains of Sólheimasandur are home to a crashed DC-3 Plane Wreck, and within the Vatnajökull National Park is the dramatic Skaftafell Nature Reserve.

Less than a kilometre from Seljalandsfoss is the hidden gem of Gljúfrabúi waterfall, and short distances from Jökulsárlón you will find the Diamond Beach, where icebergs wash on the black-sand shore, and another glacier lagoon, Fjallsárlón.

The Diamond Beach is a strip of black sand belonging to the greater Breiðamerkursandur glacial plain, located by Jökulsárlón glacier lagoon on the South Coast of Iceland.

Here, the icebergs which fill Jökulsárlón glacier lagoon wash up on shore, standing dazzling and defiant in stark contrast to the black sand beach. It is, therefore, a favourite amongst photographers, nature-lovers, and wildlife-enthusiasts. Many seals call this beach home, and it is one of the best places in the country to see orcas from the shore.

Breiðamerkursandur

Breiðamerkursandur is a glacial outwash plain located in the municipality of Hornafjörður. The sand stretches approximately 18 kilometres along Iceland’s South Coast, more specifically from the foot of Kvíárjökull Glacier to the famed glacier lagoon Jökulsárlón, that nests by the foot of Breiðamerkurjökull Glacier.

Both glaciers make up part of the 30 outlets of Vatnajökull, Europe’s largest ice cap and the central feature of the Vatnajökull National Park. Many of these are seen en route to the Diamond Beach as you travel along the South Coast.

The outwash plain was formed when three of Vatnajökull’s outlet glaciers, Breiðamerkurjökull, Hrútárjökull and Fjallsjökull, flowed forward due to volcanic activity and ground the rocks of the underlying surface, creating and pushing forward the glacial sediments.

Such sand plains are a common part of the Icelandic landscape, due to the island being volcanically active as well as boasting numerous ice caps. The terminus (the tip of a given glacier) also dug deep into the ground and left what is now the Jökulsárlón glacier lagoon. Although now the deepest lake in all of Iceland, it only began to form in 1935.

The glacier lagoon and Diamond Beach are fantastical sites, however, the rate of their expansion is, unfortunately, a consequence of climate change. With the rate that the glaciers are melting, there may be no ice left at either site within decades.

Jökulsárlón Icebergs

Jökulsárlón glacier lagoon is one of the most famed and visited attractions in Iceland. Floating on the lagoon are enumerable icebergs that have broken off the resident glacier, creating an ever-changing scenery of incredible allure.

The river Jökulsá connects the lagoon to the Atlantic Ocean, meaning that these icebergs eventually drift out to sea where they are polished by the waves before floating back to the black sands of Breiðamerkursandur. The name ‘Diamond Beach’ thus comes from the white ice on the black sand appearing like gemstones or diamonds, as they often glisten in the sun and sharply contrast their jet black surroundings.  

Safety at the Diamond Beach

The Diamond Beach is a safe place for any responsible traveller; unlike at Reynisfjara, another South Coast black-sand-beach, sneaker waves and rip currents are not notorious for whisking unwitting tourists out to sea. However, there are still dangers to consider.

The main one of these is the icebergs themselves. Under no circumstance should you climb upon an iceberg, due to their slippery surfaces and sharp edges.

This is especially the case if the iceberg is at all in the water, as it could flip and trap you underneath, or else be pulled out to sea by a current with you on it.

The risk of injury and illness in the form of hypothermia is so great that extortionate fines exist to deter any ‘rebels’ looking for a thrill-seek. These have only come about due to serious incidents, to protect not only tourists at the lagoon but guides and staff who may feel obligated to embark on a dangerous rescue if they see someone at risk.
