1. Descend Into A Volcano
There are plenty of places on Earth where you can hike up, around and above volcanoes. But so far, there is only destination where you can go
inside one. Is it any surprise that it’s located in the geological It-Country of Iceland? The dormant Thrihnukagigur Volcano can be penetrated with a little bit of exertion, a fair amount of
kroner (Iceland´s currency), and a major dose of bad-ass. You’ll have to hike about 45 minutes to get to the crater, but that’s the easy part. After, you’ll descend 400 feet through a magma chamber in an innovative, open cable lift. Once at the bottom, you can spend up to an hour exploring the volcano—or as long as you dare. ($295;
