Katla

From Dyrhólaey, Katla is just a white line on the horizon.

Closer in, the ice turns black: ash from the last eruptions.

Up close: up to 700 meters of ice over a volcano that has been silent since 1918.

As of September 22, 2026Katla today: color code green – and what is open around Vík

Katla sits under the Mýrdalsjökull ice cap, a few miles north of Vík. As of September 22, 2026 the Icelandic Met Office lists the volcano at aviation color code green and alert level 0 – normal background activity, last confirmed on September 9, 2026. Nobody climbs the volcano itself. What you visit are its edges: the ice cave in Kötlujökull, the Sólheimajökull glacier and Reynisfjara beach. And that is exactly where a lot changed in 2026.

Open – tour only

Katla ice cave in Kötlujökull

Year-round, several departures a day from Vík. Only the operators' super jeeps drive the track into the glacier forefield; there is no public parking lot. About 3 hours, including 40 minutes of driving each way.

The experienceThe Katla ice cave: under the volcano, inside the ice

Vík, meeting point in the village. The super jeep rolls across the Mýrdalssandur outwash plain, then along a track of black ash into the forefield of Kötlujökull. The last minutes are on foot over scree and ice, with crampons and a helmet. Then you stand inside the cave: ice that is not white but banded black – every dark layer is ash from an eruption. In winter the ice glows blue and the cave is stable; in summer parts melt away, but access is easier. What the cave looks like this month is up to the glacier.

The rulesHow the ice cave tour from Vík works

There is no legal requirement to take a guide – and still no way around the operators. The cave lies behind a super jeep track with no public parking, and glacier ice without a guide is life-threatening. Three operators based in Vík run year-round.

1

Book, don't just drive there

Online with the operator or through a reseller. Small groups (Katlatrack 2–12 people per guide, Arctic Adventures 1 guide per 14 guests) – book ahead in high season. Children: state their age, child seats in the jeep are mandatory.

2

Meeting point in the village

Troll Expeditions: The Vik Inn, Víkurbraut 26 (be there 20 minutes early). Katlatrack: Austurvegur 16 next to the gas station. Arctic Adventures: bus parking lot behind the Icewear building. All within walking distance, also from the Strætó bus.

3

40 minutes of track, then on foot

Across the outwash plain and an ash track into the forefield of Kötlujökull. Then 20–60 minutes of walking on ash, scree and ice, with Arctic Adventures partly on ladders. Sturdy hiking or winter boots are required; crampons and helmet are provided.

4

Minimum age and cancellation

From age 6 (Troll in summer, Arctic Adventures), from 8 in winter (Troll), from 12 with Katlatrack. Troll: full refund up to 24 hours before, minus a 3% card fee, nothing after that. Arctic Adventures: free cancellation up to 24 hours before.

Ways to the volcanoFour places on the edge of Katla

Katla has no summit trail and no crater rim for visitors. It has four edges you can reach – each with its own rule.

Tour only

Ice cave in Kötlujökull

From Vík by super jeep, about 40 minutes each way, then a short walk. About 3 hours in total (Katlatrack 3–4 hours, with one or two caves depending on the state of the glacier). From Reykjavík as an 11-hour day tour with waterfall stops.

Hikes suspended

Sólheimajökull

Road 221 off the Ring Road, gravel parking lot with restrooms. Footpath to the viewpoint at the glacier snout about 15 minutes, free. Onto the ice only with a guide – and in summer 2026 suspended because of an unstable ice ridge, a new lagoon and rockfall from Jökulhaus. Whether operators are hiking new routes again is not confirmed as of September 22, 2026.

Caution

The beach is open, the yellow-marked zone at the water is off limits. Never turn your back to the sea, keep children by the hand.

The worst caseIf Katla erupts: a text from 112, then 15 to 30 minutes

Every eruption under Mýrdalsjökull melts ice – and sends a glacial outburst flood (jökulhlaup) across the outwash plain. Civil protection expects 100,000 to 300,000 cubic meters of water per second, and 15 to 20 minutes for the farms at Sólheimar, about 30 minutes for Vík. The flood paths are considered unpredictable.

So: keep your phone switched on in Vík. In an eruption the 112 emergency center sends a text message in Icelandic and English to every phone in the area. You follow the instructions of police and civil protection and move to higher ground. The response plan was revised in 2025 because so many people are now close to the glacier; the civil protection leaflets come in five languages.

How seriously this is taken showed on July 27, 2024: an outburst flood in the Skálm river put water over the Ring Road, the police commissioner declared an uncertainty phase and had the area between Skaftártunga and Vík and around Sólheimajökull evacuated. It was not an eruption – just geothermal meltwater. The procedure was the same.

Good to knowGetting to Vík, best time, tips

Getting there

Without a car: Strætó bus 51 Reykjavík (Mjódd) – Selfoss – Vík – Höfn; according to the municipality, departures from Vík toward Reykjavík on weekdays except Wednesday at 4:00 pm, Sat/Sun 2:42 pm; ticket via the Strætó app (Klapp) or from the driver. The ice cave meeting points are in the village. No bus runs to Sólheimajökull (turnoff 221).

By car: Ring Road 1 to Vík (about 180 km / 110 miles from Reykjavík, a good 2.5 hours). Sólheimajökull: road 221 off the Ring Road, gravel parking lot with restrooms, 750 ISK via Parka. Kötlujökull: the track to the ice cave is not for rental cars, only the operators' super jeeps.

Best time to go

Ice cave: year-round; in winter (November–March) with the clearest blue ice and stable caves, but storm risk and short days; in summer parts of the cave melt, but days are long and access is easier. Sólheimajökull: summer for hikes – restricted in 2026 though. Glacial rivers carry geothermal water with gas most often in summer (June–September); the IMO notices matter most then. Reynisfjara: avoid in southerly storms and high swell – check the warning light, regardless of sunshine.

Who it suits

Children
Ice cave tours from age 6 (Troll in summer, Arctic Adventures), from 8 in winter (Troll), from 12 with Katlatrack; child seats in the super jeep are required. Reynisfjara with children only well away from the water.
Minimum age
6 / 8 / 12 years depending on operator and season
Fitness
Ice cave: easy to moderate, 1–2 km (0.6–1.2 miles) on ash, scree and ice, partly ladders (Arctic Adventures), up to 60 minutes of walking with Katlatrack. Sólheimajökull hike: moderate, crampons.
Heart and lungs
Hydrogen sulfide at glacial rivers (Múlakvísl, Jökulsá á Sólheimasandi) can irritate airways and eyes – heed IMO warnings; leave the area immediately if irritated. Cold in the cave.
Wheelchair
Ice cave and glacier not possible. Reynisfjara: parking lot and platform, beach not accessible.
Dogs
Not provided for on the tours; no rule found for Reynisfjara.
Clothing
Wind- and waterproof outer layer, warm layers, hat, gloves – around 0 °C (32 °F) in the cave, often stormy at the glacier. Operators do not rent clothing on site (Arctic Adventures).
Footwear
Sturdy hiking or winter boots required (Katlatrack: prerequisite), crampons are provided.

Tips you will need on site

  • Book the ice cave only through operators in Vík – there is no public access, and the track to Kötlujökull is no place for a rental car. Compare prices: Katlatrack charges in ISK, Troll and Arctic Adventures in US$.
  • Read the IMO news before every tour: in summer 2026 there were gas warnings at the Múlakvísl (Kötlujökull) and a hazard notice for Sólheimajökull. If your eyes or nose sting at a glacier margin, turn back immediately.
  • Keep your phone switched on in Vík: in an eruption the 112 emergency center sends a text in Icelandic and English to every phone in the area – the warning time for Vík is only 15–30 minutes.
  • Reynisfjara: read the warning light at the entrance first. At red the beach is closed, since August 2025 also the basalt columns and the cave – gate at the platform. Sneaker waves come without warning, even in sunshine.
  • Child seats: mandatory on super jeep tours, the operator provides them; state the child's age when booking.
  • Pay Sólheimajökull parking via Parka right away (750 ISK); after 24 hours 1,960 ISK is added.
  • Without a car: Strætó 51 stops in Vík, the ice cave meeting points are within walking distance; the full-day option from Reykjavík (11 hours) takes in waterfalls.

A short history

  • Katla is a central volcano with an ice-filled caldera of 9 × 14 km (5.6 × 8.7 miles, about 100 km²) under up to 700 m (2,300 ft) of ice; the volcanic system is about 80 km (50 miles) long and is regarded by the IMO as Iceland's fourth most active.
  • Around AD 939: Eldgjá fissure eruption of the Katla system with about 20 km³ of lava and tephra – one of the largest eruptions since the settlement.
  • At least 21 eruptions in 1,100 years, on average every 50 years; all three known eruptions of Eyjafjallajökull were followed by Katla eruptions.
  • October 12, 1918: last major eruption, lasting 24 days; the outburst flood pushed the coastline at Mýrdalssandur out to sea.
  • 1955, 1999, 2011: small outburst floods, probably from minor eruptions under the ice, unconfirmed; in 2011 the bridge over the Múlakvísl was swept away.
  • August 29, 2016: two earthquakes of about M4.5 in the northern caldera, the strongest since 1977 – no eruption.
  • July 27–29, 2024: outburst flood in Leirá syðri and Skálm, water over the Ring Road, uncertainty phase, evacuation between Skaftártunga and Vík, aviation colour code briefly yellow.
  • June 28, 2025: town meeting in Vík on the revised Katla response plan (2017 version updated because of tourism and new attractions close to the glacier); the civil protection plan PDF is dated October 14, 2025.
  • August 18 – early September 2026: small outburst flood in the Múlakvísl with hydrogen sulfide above limits; normal readings again on September 9, 2026.

Without a rental carKatla ice cave as a day trip from Reykjavík

About 180 kilometers (110 miles) separate Reykjavík from Vík. The day tours take in the south coast – waterfalls, black beach, then the super jeep – and run 10 to 12 hours. Back around 8 pm.

Outdated onlineWhat other sites get wrong

“Katla is overdue and could erupt any day.”
The Met Office lists Katla at green and alert level 0 as of September 22, 2026. The outburst floods of summer 2024 and 2026 were geothermal – not a sign of an eruption.
“You can climb Katla.”
The volcano lies under Mýrdalsjökull. What the tours show are ice caves in its outlet glaciers; there is no “crater climb”.
“The Katla ice cave is open in winter only.”
The Vík operators run year-round. In summer access is easier and the ice less blue – and Troll's minimum age drops from 8 to 6.
“At Sólheimajökull you can simply walk onto the glacier.”
Since July 22, 2026 the Met Office has warned of unstable ice, a new lagoon and rockfall; the operators suspended their hikes. Only the path to the viewpoint is free.
“Reynisfjara: in calm seas the cave is safe.”
Sneaker waves arrive without warning. Since August 2025 the columns and the cave are closed at red, and red is triggered earlier than before.

Quick answersBefore the drive to Vík

Is Katla volcano active right now?

Katla is an active volcano, but currently quiet: aviation color code green and alert level 0 at the Icelandic Met Office as of September 22, 2026. The last major eruption was in 1918.

How do you get to the Katla ice cave?

Only on a super jeep tour from Vík – meeting point in the village, about 40 minutes of track, then a short walk with crampons. From Reykjavík as a day tour along the south coast, 10 to 12 hours.

How much does the Katla ice cave tour cost?

With the Vík operators 39,900 ISK (Katlatrack, about US$290), US$240 (Troll) or from US$200 (Arctic Adventures); on GetYourGuide from €158 (as of September 22, 2026). Helmet, crampons and guide are included.

Can you still do a glacier hike at Sólheimajökull in 2026?

The path to the viewpoint is open. Glacier hikes were suspended by the operators after the Met Office warning of July 22, 2026; whether they are running again on new routes is not confirmed as of September 22, 2026. Ask the operator before booking.

What does the red light at Reynisfjara mean?

Beach closed – only the viewing area at the platform remains. Since August 2025 the basalt columns and the cave are also closed at red, and the gate is shut.

How far is Vík from Reykjavík?

About 180 kilometers (110 miles) on the Ring Road, a good two and a half hours by car. Without a car, Strætó bus 51 runs from Reykjavík (Mjódd) via Selfoss to Vík.

Is Katla currently active or dangerous?

As of September 22, 2026 the Icelandic Met Office lists Katla at aviation colour code green and alert level 0 (normal background activity). In August 2026 there was a small outburst flood in the Múlakvísl with gas, but no sign of an eruption. The current danger for visitors comes from glacier ice, rockfall and gas at glacier margins, not from lava.

Can you visit the Katla ice cave without a tour?

Practically no. The cave lies in Kötlujökull behind a super jeep track with no public parking, and glacier ice without a guide is life-threatening. Tours leave Vík several times a day and take about three hours.

From what age can children join the ice cave tour?

Depending on the operator from age 6 (Troll in summer, Arctic Adventures), in winter with Troll from 8, with Katlatrack from 12. Child seats in the jeep are mandatory, so state the age when booking.

How long is the tour and how strenuous is it?

From Vík about three hours, including 40 minutes of driving each way and 30–60 minutes on site and walking on ash and ice, partly with ladders. The operators rate it easy to moderate; sturdy boots are required.

Can you go onto the glacier at Sólheimajökull?

Only with a guide, and in summer 2026 only to a limited extent: on July 22, 2026 the Met Office warned of unstable ice, a new lagoon and rockfall; the operators suspended tours and are looking for new routes. Freely accessible is the footpath from the parking lot (750 ISK) to the viewpoint.

What happens in Vík if Katla erupts?

Every phone in the area receives a text from the 112 emergency center in Icelandic and English; for Vík and its surroundings civil protection expects 15–30 minutes until the outburst flood arrives. You follow the instructions of police and civil protection and move to higher ground; the response plan was revised in 2025.

What should you wear?

Wind- and waterproof jacket, warm layers, hat and gloves; in the cave it is around freezing. Sturdy hiking or winter boots are required, crampons and helmet are provided by the operator. Clothing cannot be rented on site.

Is Reynisfjara dangerous?

Yes, several people have died there in sneaker waves. A warning light at the entrance shows the level: yellow caution, orange at least 25 m (80 ft) from the water, red beach closed – since August 2025 the basalt columns and the cave are also closed at red.

Is there a gas hazard at the glacier?

At times, yes. During outburst floods hydrogen sulfide escapes at the river sources; in August and September 2026 readings at the Múlakvísl were above limits. The IMO then advises against staying near the river or glacier margin and to leave immediately if eyes or nose are irritated.

When is the best time for the ice cave?

In winter the ice is at its bluest and the cave stable, but days are short and storms frequent. In summer access is easier and tours are cancelled less often; parts of the cave may have melted by then.
