Viðgelmir is the biggest lava cave in Iceland. It is situated in Borgarfjörður close to Húsafell. This colourful cave contains beautiful lava formations, enchanting chambers and undisturbed plant life. It has recently been made more family-friendly with an accessible walk-way leading through the cave. It is only possible to visit Viðgelmir through organized tours. There is a delightful service centre located at the mouth of the cave where you can buy refreshments and soak in the beauty of Borgarfjörður in the shadow of Langjökull glacier.
Viðgelmir is only a two-hour drive from Reykjavík and less than an hour from Borgarnes. There are many other attractions to see on the way along the Hvítá River, such as Deildártunguhver, Reykholt and Hraunfossar
