The Lava Tunnel and Mega Zipline Iceland Combo Tour is an unforgettable experience for adventure seekers visiting Iceland. The tour starts with a visit to Mega Zipline Iceland in Hveragerði.  There they can zip through the air and take in the stunning views of the surrounding landscapes, including mountains, hot springs, and the stunning canyon "Svartagljúfur".  After the zipline, visitors will then head to the Lava Tunnel which is only 15 minutes away.  Your booking at the Lava Tunnel is approximately two hours after the Zipline so if your booking is at 10 am (or 10.15) for the zipline, then your booking at The Lava Tunnel will be at 12.00 noon.  So there is no need to rush and you actually should have time to grab a sandwich or a cup of coffee between the two trips.   The Lava Tunnel is a natural cave formed by flowing lava thousands of years ago. Inside the tunnel, visitors can explore the unique geological formations, such as stalactites and stalagmites, and learn about the volcanic history of Iceland.   This combo tour is perfect for those looking to combine a unique cultural and geological experience with an adrenaline-pumping adventure.
