アイスランドの自然の驚異

アイスランドの渓谷

アイスランドは世界で最もドラマチックな渓谷の一部を有しています。これらの深い谷は何千年もの間、強力な氷河川によって刻まれ、しばしば切り立った崖、滝、独特の岩の形成を特徴としています。

Iceland's canyons were shaped by immense geological forces — glacial rivers cutting through volcanic rock, explosive jökulhlaup floods, and millennia of erosion. The result is a collection of dramatic gorges ranging from narrow slot canyons to massive horseshoe-shaped valleys kilometers wide.

Many of Iceland's most beautiful canyons can be found along the South Coast, in the Highlands and in North Iceland. Popular canyon destinations include Fjaðrárgljúfur, Stuðlagil Canyon and Ásbyrgi canyon in Vatnajökull National Park.

Some canyons, like Fjaðrárgljúfur, are easily accessible from the Ring Road with well-marked walking paths. Others, like Sigöldugljúfur in the Highlands, require 4WD vehicles and summer-only access. Several canyons allow visitors to walk inside the narrow gorges, offering unique perspectives of towering cliffs and hidden waterfalls.

Planning Tip

Many canyon trails can be muddy or closed due to erosion prevention. Check local conditions before visiting. Bring waterproof hiking boots and be prepared for wet conditions when exploring slot canyons.

アイスランドの注目すべき渓谷

From the iconic Fjaðrárgljúfur to the remote Highlands gorges — explore Iceland's most spectacular canyons carved by glacial rivers and volcanic floods.

Fjaðrárgljúfur

Iceland's Most Famous Canyon

Fjaðrárgljúfur is a magnificent 2km long and 100m deep canyon carved by glacial meltwater over thousands of years. The Fjaðrá river winds through the serpentine gorge, creating stunning curves and viewpoints along the walking path.

Visitor Tips

Stay on marked paths to protect fragile moss. The viewpoint trail takes 1-2 hours round trip. Can be closed in early spring to prevent erosion. Best light for photography is late afternoon.

Stuðlagil Canyon

Basalt Column Cathedral

Ásgarðsgljúfur eru sunnan við Ásgarðsfjall á Kerlingarfjallasvæðinu. „Fullyrða má að þeirra bíði veisla sem Kerlingarfjöll sækja heim og kunna að meta fallega og fjölbreytta náttúru. Litbrigði, litir og landslag, með fjöllum, jöklum, dölum, tindum, giljum og bullandi hverasvæði bíður og ekkert eftir en að mæta á staðinn og bera sig eftir björginni. Í Kerlingarfjöllum finna allir gönguleiðir við sitt hæfi. Sumar leiðir eru merktar en aðrar eru ómerktar.“

Dimmugljúfur og Hafrahvammagljúfur

Dimmugljúfur og Hafrahvammagljúfur

east-iceland

Við Kárahnjúka eru dýpstu gljúfur á Íslandi, Dimmugljúfur og Hafrahvammagljúfur sem eru afar fjölbreytt að lögun og berggerð, víða ægifögur. Hafrahvammagljúfur eru víð og grunn vestan megin, en með miklum hamravegg að austanverðu. Á innri mörkum þeirra hefur áin grafið sig inn í dökkt gjall-klepraberg Kárahnjúkaraðar. Þar má sjá „langsnið“ af eldstöðinni, sem í jarðsögu landsins er næsta einstætt. Dimmugljúfur taka svo við af Hafrahvammagljúfrum, þar sem kallast Gljúframót. Þau eru „nokkuð jafn djúp en mun þrengri og þverhnípt beggja vegna, grafin í móberg og basaltlög, vestanvert við Kárahnjúkamyndunina“ (1). Það er einstakt að standa á brún þeirra og horfa niður en „einnig er hægt að ganga niður í Hafrahvamma og skoða þar hella og móbergskletta“ (2).

Djúpárgljúfur

south-iceland

Djúpá er „jökulá sem kemur undan suðvestanverðum Vatnajökli og fellur fram fyrir vestan Björninn um Djúpárdal, víða í gljúfrum, uns hún kemur fram á láglendið austan við Kálfafell í Fljótshverfi. Mikill foss er í Djúpárgljúfri, ekki langt frá Kálfafelli, og heitir hann Gufufoss. Fleiri fallegir fossar eru ofar í ánni.“

Fagradalsárgljúfur

east-iceland

Fagridalur er fjallaskarð milli Reyðarfjarðar og Fljótsdalshéraðs en um hann liggur þjóðvegur sem nefnist Fagradalsbraut. Vegurinn var fyrsti akvegur yfir Austfjarðafjallgarð og var fullgerður árið 1909. „Dalurinn er þröngur og klettafjöll á báða bóga“ (1). Vinsæll áningastaður (2) er við Fagradalsbraut þaðan sem gott útsýni er yfir Fagradalsárgljúfur (3).

Fannardalsgljúfur

east-iceland

Eftir Fannardalsgljúfri rennur samnefnd á, Fannardalsá. Fagrir fossar renna eftir grónu gljúfrinu og frá því er stórbrotið útsýni (1). Gilið markar upphaf gönguleiðar upp á Goðaborg (2) sem er 1132 m hátt fjall. Þess má geta að Goðaborg er hluti af gönguleik sem kallast „Fjöllin fimm“ sem Ferðafélag Fjarðamanna stofnaði til árið 2004. Felst hann í því að ganga á fimm fjöll á fimm dögum og er Goðaborg eitt þeirra (3). Skráðar athugasemdir. Hlutar leiðarinnar á viðkvæmu gróðurlendi. (4)

Geithúsaárgljúfur

Gljúfrið er einstaklega fallegt og undir það á Kjarval að hafa tekið en hann á að hafa lýst því sem „fallegasta stað á Íslandi“. Falleg gönguleið liggur meðfram gilinu og upp á Grænafelli sem er í um 600 m hæð (1). Á leiðinni er gengið fram hjá fallegum fossi, Háafossi. Á kafla meðfram gilinu er grindverk til stuðnings (2).

Kolugljúfur

Kolugljúfur

north-iceland

„Þegar ekið er fram Víðidal kemur maður að Kolugili sem stendur við Víðidalsá. Rétt neðan við bæinn rennur áin friðsæl niður í stórbrotið gljúfur sem heitir Kolugljúfur og þar eru fossar sem kenndir eru við tröllkonuna Kolu og heita Kolufossar. Það er afar áhrifamikið að aka út á brúna yfir gljúfrið og sjá hina friðsælu á steypast fram í svo mikilfenglegum fossum. Sýn sem lætur engan ósnortinn“ (1). „Góðar gönguleiðir eru meðfram gilinu sitthvoru megin, fara verður þó með varúð og hætta sér ekki of nærri gilinu. Þvergil lokar leið að vestanverðu svo ekki er hægt að ganga hringleið niður á Víðidalsbrúna“ (2).

Frequently Asked Questions

What is the most famous canyon in Iceland?

Fjaðrárgljúfur is arguably Iceland's most famous canyon, gaining worldwide attention after appearing in a Justin Bieber music video in 2015. The 2-kilometre-long canyon near Kirkjubæjarklaustur features dramatic winding cliffs up to 100 meters deep and is easily accessible from the Ring Road.

Can you walk inside Icelandic canyons?

Yes, several Icelandic canyons allow visitors to walk inside. Rauðfeldsgjá on the Snæfellsnes Peninsula is a popular slot canyon where you can wade through shallow water to explore the narrow gorge. However, many canyons have rim trails only to prevent erosion and ensure visitor safety.

Summer (June–August) offers the best access and weather conditions. Some Highland canyons like Sigöldugljúfur are only accessible via F-roads in summer. Spring and autumn can be beautiful but expect muddy trails. Winter visits are possible for accessible canyons but require caution due to ice and snow.

Do I need a 4WD vehicle to visit Iceland's canyons?

It depends on the canyon. Popular sites like Fjaðrárgljúfur, Stuðlagil (east side), Ásbyrgi and Kolugljúfur are accessible via regular 2WD vehicles. Highland canyons like Sigöldugljúfur require 4WD and are only accessible in summer via F-roads. Always check road conditions at road.is before setting out.

Are there any hidden or lesser-known canyons worth visiting?

Yes! Múlagljúfur near Fjallsárlón glacier lagoon is a stunning hidden canyon with minimal crowds. Sigöldugljúfur (Valley of Tears) in the Highlands is remote but incredibly beautiful.
