Private Silver Circle & Vidgelmir Lava Cave

This full-day private tour from Reykjavik explores the Silver Circle route, including stops at Borgarnes for fjord views, Deildartunguhver hot spring, the historic site of Reykholt, and the striking waterfalls of Hraunfossar and Barnafoss. The highlight is a guided walk through Vidgelmir lava cave, Iceland’s largest lava tube stretching over 1,500 metres, formed by the same Hallmundarhraun eruption that created the lava fields above. Inside the cave, a specialist guide leads you past stalactites, lava pillars, ice formations in winter, and chambers with ceilings up to 10 metres high. Helmets and headlamps are provided, but the cave remains cold year-round at around 4°C, so bring warm clothing. This tour suits travelers interested in geology and Iceland’s volcanic landscape, combining above-ground natural wonders with an immersive underground experience. All transport and hotel pickup in Reykjavik are included, with a private YFIR guide throughout.
