From Reykjavik: Raufarhólshellir Lava Tunnel Guided Tour with Transfers Tickets at Raufarhólshellir

The Raufarhólshellir Lava Tunnel guided tour departs from Reykjavik and travels to one of Iceland's longest and most accessible lava tubes, formed around 5,200 years ago during an eruption on the Reykjanes Peninsula. The tunnel stretches roughly 1,360 metres, with sections reaching up to 30 metres in width and height, making it among the largest lava caves in the country.

Guides lead small groups through the illuminated interior, pointing out lava formations including stalactites, flow marks, and coloured mineral deposits along the tunnel walls. Transfers from Reykjavik are included, along with helmets and headlamps. Tickets cover the guided walk, safety equipment, and return transport, with departures running on a fixed schedule throughout the year.
