Ready for an unforgettable underground journey? Let's begin!

What is the Leidarendi Lava Tube?

Leidarendi Cave is a lava tube located in a lava field close to Bláfjöll, offering easy access from Reykjavik. The Leidarendi Lava Caves were formed approximately 2,000 years ago during a volcanic eruption on the Reykjanes Peninsula. The cave stretches about 900 meters (2,953 feet) long, and there's a 150-meter (492 feet) walk to reach the entrance. 

What makes it unique is that two separate eruptions, a thousand years apart, contributed to its formation. As molten lava flowed from the crater, it formed a crust on the surface while a river of lava continued to flow beneath, creating the hollow tube that exists today.

Leidarendi Cave consists of one long tunnel that splits into smaller chambers, showcasing remarkable mineral compositions and colorful formations throughout.

Why is it Called 'End of the Road'?

The name of the Leidarendi Cave translates to 'End of the Road' in Icelandic, a fitting title tied to an eerie discovery. Deep inside the cave, explorers found a lamb's skeleton, believed to have been trapped in one of its longest corridors hundreds of years ago.

This area is now protected by a chain, symbolizing the cave's dangerous and mysterious nature. Initially, it was thought that a bandit, possibly trying to steal the sheep, placed the remains, as sheep theft was punishable by death in Iceland.

However, carbon dating revealed the bones are just over a hundred years old. Analysts suggest the lamb may have fled into the cave during a volcanic eruption or a violent storm. Its broken legs indicate the poor animal got lost in the unforgiving terrain, ultimately succumbing to the cave's harsh conditions, serving as a reminder of the importance of proper preparation when exploring.

Exploring the Cave

Exploring Leiðarendi is an exhilarating adventure, but it's important to be prepared for the challenges that come with this unique lava tube. The cave is small, with some tight, narrow passages that can feel claustrophobic, making it a bit tricky for some visitors.

Children will love the sense of adventure, but be sure to keep them close due to the many confined spaces. The varied terrain inside requires light crawling or stooping, which adds to the immersive experience. For safety and comfort, sturdy boots are essential for traction on rough lava surfaces, and gloves are recommended to protect your hands while navigating. 

Key Features of the Cave

The Leiðarendi Lava Cave is a fascinating underground wonder filled with unique natural formations. Here are the key features you'll encounter:

• Lava Stalactites and Stalagmites: The cave is decorated with drip stalagmites and shark tooth-shaped stalactites, formed over centuries as molten lava cooled and dripped from the ceiling.

• Ice Formations: During winter, the cave often features stunning ice sculptures that naturally form inside, adding an extra touch of magic to the experience.

• Polished Walls and Lava Flakes: The smooth walls of Leiðarendi display vibrant colors such as reds, yellows, and greens from mineral deposits. You'll also notice lava flakes, remnants of previous eruptions scattered throughout the cave.

• Lava Hands: One of the cave's most intriguing features is the 'Lava Hands.' These formations resemble outstretched fingers made of hardened lava, creating a mysterious atmosphere.

Legends and Myths

In Iceland's earlier days, caves like Leidarendi were feared for both practical and mythical reasons. Many lives were lost when people accidentally fell into caves or became trapped while searching for warmth during brutal winters.

To deter people from entering, folklore arose, portraying caves as the homes of trolls. These creatures were thought to be proud, magical, and violent, punishing or even eating anyone who trespassed. Caves were also dangerous hideouts for bandits and outlaws, avoiding capture. While Iceland has modernized and such dangers have faded, the fear of caves persisted for many years.

Without social safety nets, some impoverished Icelanders used caves as shelter during winters, even into the twentieth century. However, Leidarendi itself is not known for troll legends, nor was it a hideout for bandits or a shelter for those in need. Today, it is a much safer place for exploration, but its history still stirs the imagination.
