Into the Glacier Ice Cave Tour and Lava Cave Day Trip from Reykjavik with Live Guide and Touch-Screen Audio Guide

Your day trip starts with a drive out of Reykjavik, enjoying a crisp morning view of Langjökull, the second-largest glacier in Iceland. This tour does not have scheduled lunch time so please bring lunch with you.

When you arrive at the glacier, you'll find yourself swiftly standing on top of the ice cap before descending beneath the surface aboard a specially modified glacier vehicle to reach the man-made ice cave, aka ice tunnel; during this experience, learn from your guide how global climate change has impacted the surrounding area.

Deep in the glacier, you can admire the stunning blue ice and learn about the glacier's constant movement, which you'll witness firsthand. Until very recently, what lies below Langjökull was a mystery, but bold ideas sometimes come to life, and the creation of this man-made ice cave was possible because of help from top engineers and renowned geophysicists. Inside the glacier, where temperatures are usually about 32˚ Fahrenheit (0˚ C), you can see from the layers of ice how the glacier was formed.

After this, return to the warmth of the vehicle, and head straight to Iceland's mightiest lava cave, Víðgelmir. Just shy of 5,250 feet (1,600 meters), Víðgelmir is one of the largest largest lava caves in the world. Your guide will show and explain to you the features of the cave, including its colors, lava and ice formations, and stalactites and stalagmites.

The lave field was formed during a volcanic eruption in the 10th century, originating under Langjökull. During the eruption, some of Iceland's waterfalls were created, such as Barnafossar and Hraunfossar. Mention of the lava cave dates back to 1398, and remains of human presence dating back to the Viking age were discovered in 1993. Thanks to a new signature walkway and feature lighting, the lava cave tour is family friendly.

Afterward, your day trip ends with the scenic drive back to Reykjavik.
