Visitors to Iceland’s capital have the singular opportunity to descend 394 feet (120 meters) into a dormant volcano that erupted some 4,000 years ago. Iceland is a hotbed of volcanic activity — one of the most active volcanic regions on the planet — yet the Thrihnukagigur volcano has been dormant for thousands of years. Inside the Volcano equips visitors to explore this natural wonder on a five- to six-hour tour.
The adventure begins with a 2-mile (3-kilometer) hike to the volcano across a stunning lava field. Visitors then board an open elevator for a six-minute journey into the magma chamber of the volcano. Back on the surface, participants warm up with a bowl of traditional Icelandic meat soup and a warm beverage before heading back across the lava field and continuing on to Reykjavik.
Be sure to wear good hiking shoes that you don’t mind getting dirty and a warm jacket, as the temperatures within the crater are always about 42 degrees Fahrenheit (5 degrees Celcius).
