Be ready for convenient pickup at your Reykjavik accommodations around 8am. Board a comfortable bus and find your seat, equipped with WiFi and a USB charger. Each seat also comes equipped with a tablet, which provides GPS-sensitive audio guide in 10 languages.
The UNESCO-listed Thingvellir National Park is the first stop. There, you'll learn about the Althing, one of the world's oldest parliaments. The park is also home to the location where the American and Eurasian tectonic plates have been dramatically pulled apart; the rift makes great photos.
Continue to Geysir geothermal area, where you'll visit the very active Strokkur geyser. Take a walk around the Gullfoss Waterfall, where runoff from the Hvítá glacial river drops over two levels into a canyon.
To keep exploring the rugged terrain of the central highlands, hop aboard a custom super truck bound for the snowmobile base camp at the foot of the Langjökull Glacier. There, you'll transfer to a snowmobile to ride across the snow and ice fields of the white wilderness.
After a day of adventure, relax on board the bus as you're whisked back to Reykjavik and dropped off around 7pm.
