The best lava caves in Iceland<\/h2>\n\n

More than 500 lava tunnels are known to exist in Iceland, many of them still unknown. Some are easily accessible on a road trip, others require hiking or special equipment. Some remain accessible in winter.<\/p>\n\n

If you have to visit only 1, our favorite is Vidgelmir, especially as you can combine it with the Hraunfossar waterfall on the Silver Circle. It can be visited in summer and winter.<\/p>\n\n

Be careful, we’re talking about lava caves, which sometimes have ice inside. If you’d like to visit ice caves under glaciers in winter, see our dedicated article.<\/a><\/p>\n\n

Things to know before visiting a lava cave<\/h3>\n\n

Whatever cave you choose, a few precautions are essential. Wear closed-toe shoes, ideally hiking boots. Take several layers of clothing with you, as the temperature inside often differs from that on the surface. We do not recommend these visits if you suffer from claustrophobia. Finally, always listen to the guide’s instructions and wear your safety helmet correctly.<\/p>\n\n

Why visit it? Our review<\/h3>\n\n

Vidgelmir is our favorite lava cave in Iceland. This volcanic tunnel, the longest in the country, stretches for 1585m. In its widest section, it reaches over 16m in width for an equivalent height. The dimensions are striking, and we were struck by the diversity of lava formations lining the walls: congealed flows, minerals in a variety of hues and surprising textures.<\/p>\n\n

In winter, water seeping through the rock is transformed into ice sculptures inside the tunnel, creating a striking contrast between dark lava and translucent ice. It’s well worth the detour, especially as the guides are friendly and enthusiastic. We recommend this visit to all travelers passing through West Iceland.<\/p>\n\n
