Tour itinerary

Our adventure begins when we collect you in Reykjavik and head towards West Iceland – stopping off at some wonderful places along the way. The journey will take us through the beautiful Borgarfjörður – a majestic fjord replete with mighty mountains, crystalline waters, and a luscious green landscape. We will find Deildartunguhver nearby, an impressive hot spring that is the most powerful in the entire of Europe. It supplies many of the houses in the surrounding area with central heating and hot water, ensuring that this incredible natural wonder is also one of the world’s most eco-friendly hot water systems.

We will also stop at the stunning Hraunfossar waterfall, which everyone agrees is one of the most beautiful waterfalls in all of Iceland. It is made up of thousands of tiny cascades that combine into a frothy white mosaic that buzzes with energy. It is surrounded by volcanic rocks that have been colored various shades of red, yellow and black – creating a gorgeous natural backdrop to the spine-tinglingly beautiful scene.

We will then arrive at the entrance to the Víðgelmir cave – one of the largest naturally formed lava caves in the entire world. There, we will meet our friendly tour guide, who will provide us with all the gear we need and give us any relevant safety information before we enter the cave. Then, once everyone is ready, we will start to descend into Víðgelmir itself – a subterranean natural wonder famed for its twinkling icicles and multicolored rock formations.

It begins in a narrow tunnel that provides the perfect contrast to the expansive hall that stands at its end. There we will see rainbow-colored walls that have been dyed various shades of turquoise, lilac, and amber by the mineral activity in the cave. This is coupled by shard-like rocks that dangle from the ceiling and greatly enhance the beauty of the scene. It is an awe-inspiring sight that is totally unique, and you are bound to appreciate the eerie beauty of the scene.

Víðgelmir (148000 m3) was formed around 1100 years ago, during the Viking age, by an eruption of the volcano that lies beneath the Langjökull glacier. Our expert guide will also tell us everything that we need to know about the incredible volcanic forces that created this majestic geological wonder and the many stories and legends that are associated with the area.

Once we have seen all the magic that Víðgelmir has to offer and have returned to the surface, then we will head to the geothermal pool in Húsafell for a relaxing soak amidst spectacular natural scenery and then head back to Reykjavik after a day that has had absolutely everything.
