Full description
Most visitors to Hraunfossar never realise that Iceland's largest lava cave is a 10-minute drive away. This tour does not let that opportunity pass. The Silver Circle base route — Borgarnes, Deildartunguhver, Reykholt, Hraunfossar — leads directly to Vidgelmir, a lava tube over 1,500 metres long formed in the same Hallmundarhraun eruption that created the lava field above. Your YFIR guide draws the connection before you descend. Inside, a specialist cave guide leads you through stalactites, lava pillars, chambers up to 10 metres high, and ice formations in winter. About one hour underground. The cave is 4°C year-round — a warm layer is essential even in July. Helmet and headlamp provided on-site. Private tour, hotel pickup included.
Iceland's largest lava cave is 10 minutes from Hraunfossar. Most visitors drive straight past it. This tour doesn't. The Silver Circle follows the base route — Deildartunguhver, Reykholt, Hraunfossar — before adding a guided walk through Vidgelmir, a lava tube stretching over 1,500 metres. The cave was formed in the same Hallmundarhraun eruption that created the lava field at Hraunfossar. Your guide makes the connection explicit: you see what the lava did above ground, then you descend into the tube it left behind.The cave is professionally lit and guided by a specialist cave guide who handles the underground section. Stalactites, ice formations (in winter), lava pillars, and chambers where the ceiling reaches 10 metres. The walk takes about an hour. The temperature inside is cold year-round (approximately 4°C) — bring a warm layer even in summer.Helmets and headlamps are provided on-site. The Silver Circle gives you Iceland above ground. Vidgelmir gives you Iceland below it.

...i did not get water as ordered.the driver was a very good fellow but nt a guide
Guide was very knowledgeable and friendly.
Excellent! Our guide was wonderful and kept the pace appropriate for my husband who has mobility issues. Although we didn’t see many cats, we learned a lot of interesting things about the city.
