Tips
- Choose the tour by what you want to do. The Standard Lava Tunnel Tour and the Evening Lava Tunnel Tour both last 1 hour and cost ISK 8,900; the Standard Tour With Transport costs ISK 14,900 and includes the bus fare from Reykjavík, which suits visitors without a car. The operator also sells combinations: Lava Tunnel and Lava Show (4 hours, ISK 13,490), Lava Tunnel and Perlan (7.5 hours, ISK 14,990), Lava Tunnel and Megazipline (3 hours, ISK 16,300), Lava Tunnel and Northern Lights Evening Tour (5 hours, ISK 25,990) and Lava Tunnel Walk and Whale Watching (7 hours, ISK 27,990). The combination with the Lava Show links two lava experiences: the Lava Show in Vík pours real lava at about 1,100 °C, while the tunnel shows the empty tube that a flow leaves behind. For an indoor ice cave without leaving the capital, compare Perlan. Dress for a cave and read the full set of weather and road advice in is Iceland safe?.
