Map of the Must-Visit Caves in Iceland
This map highlights the must-visit caves in Iceland, including ice caves, lava caves, and unique cultural caves across the country. It shows where each cave is located in relation to major routes like the Ring Road, the South Coast, the Golden Circle, and West Iceland.
In the sections below, we dive deeper into each cave, covering what makes it unique, how to visit it, and what to expect once you arrive.
Must-Visit Iceland Ice Caves
Ice cave experiences in Iceland range from natural caves within glaciers to man-made ice tunnels and indoor exhibits. Natural caves change with the ice, meltwater, and weather, while constructed options provide more predictable access.
Availability varies by type, season, and conditions. Some natural ice caves in Iceland open only in winter, while other natural and man-made options may be available year-round.
Below are the most notable natural and man-made ice cave experiences in Iceland. Each offers a different way to explore or learn about the country’s glaciers.
Crystal Ice Cave in Vatnajokull Glacier
The Crystal Ice Cave is a natural glacier ice cave in Breidamerkurjokull Glacier Tongue, an outlet of Vatnajokull Glacier. The cave changes or reforms each year as the glacier moves and melts. It is a standout stop on a Vatnajokull ice cave tour.
The cave is generally open from October to April when conditions allow. Our study of the safest month to visit ice caves in Iceland found February to have the most stable ice of that season.
The Crystal Ice Cave is known for its dense blue ice, although its appearance varies each season. Natural light entering through the cave opening can illuminate the ice and enhance its blue tones.
This cave should only be entered on a certified Crystal Ice Cave tour. You'll be provided with crampons, a helmet, and any other required safety equipment. Most tours depart from the Jokulsarlon Glacier Lagoon area.
Katla Ice Cave in Myrdalsjokull Glacier
If you are visiting outside the winter season, the Katla Ice Cave is the most reliable option for seeing natural ice caves in Iceland. Located within Kotlujokull, an outlet glacier of Myrdalsjokull, it is the only natural ice cave in Iceland that remains accessible year-round when conditions allow.
Many natural ice caves in Iceland become unsafe or inaccessible during the summer melt. At Katla, layers of volcanic ash help slow the melting process, although the caves still change and guides adjust routes according to current conditions. This makes it the top choice for travelers searching for ice caves in Iceland in summer.
Katla is known for its dramatic black-and-blue ice. Dark volcanic ash from past eruptions of the Katla Volcano runs through the ice, creating a moody, high-contrast look that is very different from the bright blue caves of Vatnajokull.
Visits are only possible with a guided Katla ice cave tour in Iceland, with most tours departing from the village of Vik. Reaching the cave involves a Super Jeep drive across volcanic terrain. Minimum ages for Katla ice cave tours in Iceland vary, so families should check the requirements before booking.
Into the Glacier Ice Tunnel in Langjokull Glacier
Into the Glacier, the world’s largest man-made ice tunnel, offers a year-round ice cave experience inside Langjokull Glacier. Unlike natural ice caves in Iceland that change or disappear each season, this 1,640-foot (500-meter) tunnel allows visitors to explore the interior of a glacier throughout the year.
The tunnel has lighting and several chambers carved directly into the ice. Its floor can be uneven, wet, and slippery, so visitors receive crampons for the one-hour walk. An Into the Glacier tour in Langjokull has no age restriction, although very young children should be carried in a baby carrier.
Tours depart from Reykjavik, Husafell, or Klaki Base Camp. Other Langjokull tours include snowmobiling, glacier hikes, and Super Jeep trips. Modified glacier vehicles reach the tunnel, which normal cars cannot access. This makes it a reliable summer option for travelers interested in Iceland’s ice caves.
Perlan Ice Cave in Reykjavik
While not a natural formation, the ice cave in Perlan Museum is a practical option for travelers short on time or visiting during poor weather. Located in Reykjavik, it is the world’s first indoor ice cave, built using more than 350 tons (318 metric tons) of real Icelandic snow and ice.
It offers an ice cave experience without leaving Reykjavik, which makes it convenient for a layover or stopover in Iceland. Admission to Perlan Museum gives you access to the cave, which is part of the Wonders of Iceland exhibition.
Unlike natural Icelandic ice caves that can close due to weather or melt conditions, the Perlan Ice Cave is kept at about -13 C (9F). Its controlled indoor setting provides a year-round way to experience an ice cave in Iceland.
Must-Visit Lava Caves in Iceland
Lava caves in Iceland reveal the volcanic side of the country. Many formed when the surface of a lava flow cooled and hardened while molten lava continued moving below, eventually leaving hollow tunnels.
Our study of how often volcanoes erupt in Iceland puts the long-term average at roughly one eruption every four to five years. Lava caves offer a way to explore the traces of past eruptions long after the lava has cooled.
Below are some of the most impressive lava caves in Iceland. They include accessible options near Reykjavik and larger lava tubes in West Iceland and the Snaefellsnes Peninsula.
These caves can also reveal how Iceland’s volcanic landscape developed over time. A lava cave guide from the Inside the Volcano tour describes the experience this way:
Of course, our caves work like time machines, and the deeper down you go, the further back you travel.
Thrihnukagigur (Inside the Volcano) Lava Cave Near Reykjavik
Thrihnukagigur offers one of the most unique cave tours in Iceland and a volcanic experience found nowhere else in the world. This is the only place where you can safely descend into an empty magma chamber inside a dormant volcano, rather than walking through lava tunnels or ice caves.
Around 4,500 years ago, the magma beneath Thrihnukagigur is believed to have drained away, leaving behind an underground chamber large enough to fit the Statue of Liberty. An Inside the Volcano tour uses an open cable lift that lowers 400 feet (120 meters) down into the volcano, revealing rock walls stained red, yellow, and purple.
The Thrihnukagigur tour operates seasonally from May to October and includes a hike of about 2 miles (3 kilometers) each way across a lava field. Located around a 30- to 40-minute drive from Reykjavik, Thrihnukagigur offers an accessible option for travelers interested in Icelandic caves and volcanic geology.
Ragnar describes the hike as moderate, with a maintained path and no climbing, although the final section is slightly steep. He recommends checking the weather forecast, dressing for the conditions, and wearing good shoes.
Raufarholshellir Lava Cave Near Reykjavik
Raufarholshellir is one of the most impressive lava caves near Reykjavik and one of the best-known lava caves in Iceland. Located about 30 minutes from the capital, this tunnel formed more than 5,200 years ago during the Leitahraun eruption and reaches up to 98 feet (30 meters) wide and 33 feet (10 meters) high.
What makes this lava cave stand out is the color inside. Entry to Raufarholshellir reveals mineral-rich lava walls with deep reds, oranges, yellows, and hints of green, which makes it one of the most visually striking lava caves in Iceland.
Access is via a guided Raufarholshellir lava cave tour in Iceland, with lighting and a raised walkway that make it suitable for most visitors. The cave is open year-round, and in winter, ice formations beneath natural skylights create a dramatic fire-and-ice contrast.
Vidgelmir Lava Cave in West Iceland
Vidgelmir is the largest lava cave in Iceland by volume. Located in West Iceland near Husafell, this massive lava tube formed around 900 A.D. and stretches nearly 1 mile (1.6 kilometers) into the lava field.
The cave features a wooden walkway, handrails, and fixed lighting, allowing comfortable access through its enormous interior. Some chambers reach nearly 52 feet (16 meters) high and feel more like underground halls than a typical cave.
Inside, Vidgelmir preserves some of the best lava formations in Iceland, including lava stalactites and flow structures that remained untouched for centuries while the cave was sealed by ice. Visits are available on a guided Vidgelmir lava cave tour and can be combined with nearby attractions in a West Iceland day trip from Reykjavik.
Vatnshellir Lava Cave in Snaefellsnes Peninsula
Vatnshellir Cave is one of the most distinctive lava caves in Iceland. Located beside the Snaefellsjokull Volcano, the lava tube formed around 8,000 years ago during an eruption from the nearby Purkholar craters.
Snaefellsjokull is the fictional entrance to the underground world in Jules Verne’s “A Journey to the Center of the Earth.” While the novel’s characters descend through the volcano, Vatnshellir offers a real descent into the same volcanic landscape.
Inside, the walls are lined with lava formations, including mineral-streaked rock in varied colors. At the deepest point, you can switch off your flashlight, allowing you to experience complete darkness far below the surface.
Visits are only possible on a guided Vatnshellir lava cave tour, with the cave located about 2.5 to 3 hours from Reykjavik within Snaefellsjokull National Park.
Must-Visit Unique Caves in Iceland
Not all caves in Iceland are shaped only by ice or lava. Some are tied to history, folklore, and pop culture. These unique and man-made caves in Iceland range from famous filming locations to ancient dwellings carved by early settlers, many of which are easy to reach on self-drive trips or short guided day tours.
Below are some of the most distinctive cultural and historical caves in Iceland, combining scenery, storytelling, and accessible locations across the country.
Yoda Cave (Gigjagja) in Iceland’s South Coast
Yoda Cave, also known as Gigjagja, is one of the most recognizable Icelandic caves thanks to its famous silhouette. Located at the base of Hjorleifshofdi Mountain along the South Coast, the cave opening resembles the head of Yoda when viewed from inside, attracting many Star Wars fans.
The surrounding area adds to its appeal. The black sand plains of Myrdalssandur and the cliffs of Hjorleifshofdi were used as filming locations for “Rogue One: A Star Wars Story,” giving the site a real cinematic connection beyond the visual resemblance.
Yoda Cave can be reached on a self-drive trip, about 15 minutes east of the town of Vik. A short walk leads from the parking area to the cave entrance, which makes it a convenient stop for travelers exploring caves in Iceland along the Ring Road.
Loftsalahellir Cave Near Vik
Loftsalahellir is a small but striking cave near Vik that has become popular for its coastal views and natural framing. This tuff-rock cavern is known for its triangular opening that frames the black sand coastline and the Dyrholaey Sea Arch in the distance.
The cave is best appreciated from the back, where the rock walls create a natural frame for photos, especially when low light highlights the cliffs and shoreline. Beyond photography, Loftsalahellir also has local historical value, as it was once used as a gathering point by farmers in the area.
Loftsalahellir is near Road 218, with a small parking area below the cave. The walk takes about 3 to 5 minutes, but the final slope is steep and can be muddy or slippery. The parking area can also be bumpy. Sturdy shoes are recommended for travelers exploring caves in Iceland.
Caves of Hella in South Iceland
The Caves of Hella are one of the most unusual caves in Iceland and a major archaeological mystery. Located on a historic farm beside the Ytri-Ranga River, the site includes 12 man-made sandstone caves, with several opened to visitors in recent years.
The caves’ origins remain unknown. Some historians have suggested that they predate the Norse settlement of Iceland and may have been carved by Celtic settlers or Irish monks known as the Papar. Inside, visitors can see crosses, wall carvings, and seats carved into the sandstone.
Access is only possible on a guided Caves of Hella tour led by the family that has owned the land for generations, adding local history to one of the most distinctive cave tours in Iceland.
Laugarvatnshellir Cave in the Golden Circle
Laugarvatnshellir tells a much more recent and personal story of life inside caves in Iceland. Located along the Golden Circle near Laugarvatn, these two caves were used as full-time homes in the early 20th century.
Indriði Guðmundsson and Guðrún Kolbeinsdóttir lived in the caves for about a year beginning in 1910. In 1918, Jón Þorvarðarson and Vigdís Helgadóttir moved in and stayed for four years, raising three children there.
Today, you can visit the site on a guided tour of the Laugarvatnshellar, which takes you through the restored living spaces and explains how the families lived and worked inside the caves.
Game of Thrones Cave (Griotagja) in North Iceland
Griotagja is one of the most famous lava caves in Iceland, located near Lake Myvatn in North Iceland. This small lava cave became internationally known after appearing as one of the Game of Thrones locations in Season 3 for Jon Snow and Ygritte’s cave scene, turning it into a must-see stop for fans of the series.
Inside the cave, a geothermal hot spring fills a narrow fissure with strikingly clear blue water. However, bathing in Griotagja is not allowed.
Geological activity in the late 20th century caused dangerous temperature fluctuations, and soaking is now prohibited to protect visitors. Travelers interested in geothermal bathing can book admission to the Earth Lagoon Myvatn, located a short drive away.
Explore Caves in Iceland
Caves in Iceland offer very different experiences depending on type, location, and season. Ice caves appear inside glaciers during winter, lava caves reveal ancient volcanic activity year-round, and unique cultural caves add history, film locations, and everyday life to the landscape.
Knowing which caves are seasonal, which require guided tours, and which work as simple self-drive stops makes planning easier and avoids unrealistic expectations. With the right timing, exploring caves in Iceland becomes a natural and rewarding part of traveling through the country.
Iceland offers far more than its most familiar sights, often challenging the truth behind common myths about Iceland. Seeing how cave visits fit alongside other experiences helps put them in context with the most unique activities in Iceland.
