Ultimate 9-Hour Golden Circle Tour with Lava Tunnel Adventure from Reykjavik

Discover Iceland's most popular tourist route and explore a fascinating lava tunnel with this combination Golden Circle tour. Travelers who want to see the three main Golden Circle attractions and visit the Raufarholshellir lava tunnel should book this exciting day tour today.

The tour begins at the BSI Bus Terminal in Reykjavik, where you'll meet your expert local guide for the day and board the bus. The bus will take your group to a lava tunnel to start your sightseeing adventure underground.

Raufarholshellir is one of the longest lava tunnels in Iceland, measuring a total distance of around 4,500 feet (1,360 meters). In parts, it's as much as 32 feet (10 meters) tall and almost 100 feet (30 meters) wide.

Your group will walk approximately 380 yards (350 meters) into the tunnel to explore the cave. Beautiful columns of light reveal the stunning colors inside, formed by various minerals. Your guide will explain how volcanic activity shaped the tunnel as you enjoy your surroundings and take photos.

You'll receive a helmet and a flashlight during this section of the tour so you can see clearly and stay safe. In rainy or snowy weather, water can drip down from the top of the cave, so it's a good idea to wear a waterproof raincoat to keep dry.

After around one hour in the lava tunnel, you'll board the bus once more to start your journey around the Golden Circle. This tourist route covers three of the best sights in South Iceland: the Gullfoss waterfall, the Geysir geothermal area, and Thingvellir National Park.

The Geysir geothermal area is home to the world-famous Geysir hot spring, which gave its name to all other geysers worldwide. Geysir is less active these days, but the nearby Strokkur geyser erupts every five to ten minutes. Enjoy the fantastic view of the erupting water and learn more about geothermal energy in Iceland.

Next, you'll head to the magnificent Gullfoss waterfall, known in English as the Golden Falls. It's a dramatic two-tiered waterfall on the Hvita river. Water cascades down a total of around 105 feet (32 meters). It's truly spectacular, and you'll have time to take lots of photos while you're here.

The day's final stop will be Thingvellir National Park, one of three national parks in Iceland and the site where the first Icelandic parliament was formed in 930 AD. On your way, the guide will explain the area's historical significance. You'll then have some time to explore.

Thingvellir National Park is home to many natural features, including lava fields, glacial springs, mountains, lakes, and ravines. It's also the location of a rift valley that sits between two tectonic plates. 

When you've finished sightseeing at Thingvellir National Park, the bus will take your group back to Reykjavik Bus Terminal. You're then free to continue your adventures or return to your accommodation.
