Modified monster trucks climb 1,260 meters above sea level to reach a 550-meter tunnel carved directly into the glacier. Inside, you walk past bands of volcanic ash and compressed blue ice that froze over a thousand years ago.
Find Guided ToursCovering 870 square kilometers across the western Highlands, Langjökull is Iceland's second-largest ice cap and the closest major glacier to Reykjavík. The "Long Glacier" reaches thicknesses of up to 580 meters and sits directly above two to three active volcanic systems. Meltwater from this 195-cubic-kilometer ice mass feeds Þingvallavatn and the Gullfoss waterfall.
The ice cap is shrinking. It has been retreating since 1840, when it hit its largest recorded surface area. The highest point rises 1,450 meters above sea level at the northern end, an area historically called Baldjökull. From the surface, you see a vast white expanse flanked by the Jarlhettur mountains and the outlying Eiríksjökull glacier.
In 2010, tour operators Baldvin Einarsson and Hallgrímur Örn Arngrímsson began carving into the ice cap at an elevation of 1,260 meters. They wanted people to see the glacier's deep blue interior. Excavators removed roughly 5,500 cubic meters of ice to create a 550-meter-long cavern.
The site opened on 1 June 2015. It's the world's largest man-made ice tunnel. Walking through the passages reveals compressed ice layers over 1,000 years old, separated by dark bands of volcanic ash from historic eruptions. The interior stays at a constant 0°C year-round. That makes it one of the only places on earth where you can explore a glacier's interior in the middle of summer.

The 550-meter man-made tunnel cuts straight into the ice cap at 1,260 meters above sea level. You'll walk on slushy snow in constant 0°C temperatures, wearing provided crampons. Look at the walls to spot 1,000-year-old compressed blue ice and dark bands of volcanic ash from past eruptions.
Standard vehicles can't handle the highland ice. You transfer into specially modified glacier trucks at Klaki Base Camp for a 30 to 75-minute climb onto the white expanse. The bumpy ride passes jagged terrain, offering clear views of the neighboring Eiríksjökull glacier and the Kerlingafjöll mountain range.
Guides lead one-hour snowmobile rides across the glacier's surface, weaving through marked safe zones to avoid hidden crevasses. You can meet operators directly at Gullfoss or Geysir on the Golden Circle. Drivers need a valid license, and passengers must be at least eight years old to hold on.
Langjökull's runoff feeds some of West Iceland's major sites. Stop at Hraunfossar on the way to Húsafell. Clear springs pour out of a lava field formed around 930 AD, creating a cascade nearly a kilometer wide. Afterward, you'll find the Krauma Geothermal Baths just 30 minutes away.

Free Cancellation 10h Summer offers the easiest access, with the gravel Route 550 open for self-driving from early June to mid-October and plenty of daylight for long tours. Winter brings reliable snow for snowmobiling and clear skies for Northern Lights, though short days and closed roads mean you have to book a guided trip.
Highland roads remain closed to regular traffic. You'll need a guided tour or a modified glacier vehicle to reach the ice cap, dealing with unpredictable snow, rain, and frost.
Route 550 opens to 4x4s on June 1, so you can drive directly to Klaki Base Camp. Maximum daylight gives you plenty of time to add Golden Circle stops.
Self-drive access ends when Route 550 closes on October 15. Late autumn brings rain and frost that ruin the gravel tracks, forcing you to rely on operator shuttles from Húsafell.
Expect the most reliable snow for snowmobile tours and clear air for spotting the Northern Lights. Daylight shrinks to just four or five hours, limiting your full-day itinerary options.
Langjökull itself is open highland terrain with no official gates or closing times. The Into the Glacier ice tunnel operates year-round, though specific departure times depend on the season and your booking. Self-driving access changes drastically by month. The gravel Route 550 to Klaki Base Camp only opens to 4x4 traffic from 1 June to 15 October. Outside those dates, you can only reach the ice via an operator's shuttle from Húsafell.
| Category | Price |

Book ice tunnel and snowmobile tours in advance, particularly in summer when seats on the modified glacier trucks fill fast. Arrive at least 15 minutes before your scheduled departure to catch the mandatory safety briefing. Independent travel on the ice cap is highly dangerous and strongly discouraged due to hidden crevasses.

Langjökull sits 150 kilometers from Reykjavík, requiring a drive to Húsafell or Klaki Base Camp before transferring to a modified glacier vehicle. You can drive yourself in summer with a 4x4, but winter visits or standard rental cars require a shuttle or guided tour.
📍 No exact street address; West Icelandic Highlands
Take Route 1 from Reykjavík toward Borgarnes, then switch to Routes 50 and 518 to reach Húsafell. Follow the unpaved Route 550/518 to Klaki Base Camp at the ice cap's edge. This rough highland stretch only opens from June 1 to October 15. Standard vehicles cannot make the climb. Rent a 4x4.
Visitors driving standard cars must park at the Húsafell Center. A tour shuttle picks you up for the 30-kilometer drive up the gravel road to Klaki Base Camp. Once at the base, everyone transfers into a modified monster truck for the final ascent onto the ice. The ride takes between 30 and 75 minutes each way depending on seasonal snow levels.
Operators like Arctic Adventures and Reykjavik Excursions run full-day trips directly from the capital. Coaches pick guests up at their hotels and drive the Golden Circle route to Húsafell. You'll avoid the stress of navigating highland roads entirely. At Húsafell, guides move the group into specialized glacier trucks for the tunnel visit.
You don't have to start in Reykjavík. Several operators run meet-on-location excursions departing straight from Gullfoss or the Geysir geothermal area on the Golden Circle. Super Jeeps cover the final 60 to 70 kilometers to the glacier. This skips the long capital transit and gets you straight onto the ice for snowmobiling.

The ice tunnel stays at a constant 0°C year-round. Forget about summer weather outside. You need a windproof coat, thermal layers, and waterproof boots, plus sunglasses to handle the intense snow glare during the outdoor ride. Operators provide the required crampons.
Route 550 to Klaki Base Camp is a rough gravel track open only from June through mid-October. You absolutely need a 4x4 to drive it. If you rented a standard car, park at Húsafell Center. From there, jump on the operator's shuttle for the ride up the mountain.
Use the restrooms at Klaki Base Camp or Húsafell Center before heading up. The glacier has almost no facilities. You will find only an emergency portable toilet near the ice cave entrance. Expect to be out on the ice for three to four hours.
Walking the tunnel floor feels like pushing through deep sand. It is entirely uneven, slushy snow. Getting there requires climbing five tall steps to board the modified glacier trucks, and only foldable wheelchairs fit inside. Staff cannot carry passengers. Consider your mobility limits before booking.
Seats on the glacier trucks regularly sell out during summer. Book your tickets well in advance. You must arrive at least 15 minutes before your scheduled departure time. If you miss the mandatory safety briefing, you lose your spot on the tour.
Snowmobile drivers must hold a valid driver's license. Passengers have to be at least eight years old. The sleds do not have safety harnesses. Anyone riding on the back needs enough upper body strength to hold on unaided for the full hour.
Clear springs cascade across nearly a kilometer of the Hallmundarhraun lava field into the Hvítá river. The field formed during an eruption around 930 AD. Just upstream, Barnafoss forces the water through dramatic narrow rapids.
This spa draws its water directly from Deildartunguhver, Europe's most powerful hot spring. Soak in several pools of varying temperatures or hit the cold plunge. Stop here to thaw out after a freezing glacier tour.
Langjökull's own meltwater feeds this massive two-tiered waterfall. The river drops 11 meters, then another 21 meters straight into a rugged canyon. Paved paths give you clear views of the churning water.

You can drive a 4x4 to Klaki Base Camp at the glacier's edge, but only between June 1 and October 15. Take Route 1 from Reykjavík to Húsafell, then the gravel Route 518/550. Regular cars cannot make this drive, and no personal vehicles are allowed onto the ice cap itself.
The Classic Tour starting from Húsafell or Klaki Base Camp costs 24,900 ISK per person. Full-day guided bus tours with Reykjavík pickup run about $279. You must book through a licensed operator to access the tunnel.
The standard ice tunnel tour from Húsafell takes 3 to 4 hours, with about an hour spent walking inside the glacier. Add another 2 to 2.5 hours each way if you are driving the 150 km from Reykjavík. Full-day coach tours from the city usually run 9 to 11 hours.
Dress in warm, waterproof layers even in July. The tunnel stays at a constant 0°C (32°F) year-round. Bring a windproof coat, gloves, waterproof boots, and sunglasses to handle the intense glare off the snow outside.
It isn't well suited for wheelchairs. You have to climb five 40 cm steps to board the modified glacier trucks, which only have space for foldable chairs. Inside, the tunnel floor is slushy snow, making it comparable to pushing a wheelchair through deep sand.
Children of any age can join the Classic ice tunnel tour. Guides recommend a baby carrier for toddlers under two because the ice floor is uneven. If you want to book a snowmobile tour, passengers must be at least 8 years old and able to hold on without a safety harness.
Yes, the ice tunnel operates year-round. Between late October and May, the highland roads close to self-drive traffic. You'll need to park at Húsafell and take the tour operator's shuttle up to the ice cap.
No. Safetravel.is warns against independent travel on Langjökull due to constantly shifting ice and hidden crevasses. You must book with a certified guide to safely navigate the surface.
