Journey to the center of the Earth on a three-day diving expedition to the North American and Eurasian tectonic plates in Iceland's crystal clear waters with London-based travel firm Black Tomato. Adventure addicts fly into Reykjavik and crash at the hip Hotel 101 for the night. The next morning, a Black Tomato guide leads a jeep safari into the heart of the geo-thermal and active plate tectonic area of Iceland, where divers, with guidance from instructors, can explore the underwater landscape between two tectonic plates, which are "effectively holding' the world apart," according to the travel company.
Afterwards, it's back to Reykjavik to hit the bar scene and toast the conquest. But this trip offers little rest for the weary. The next day, it's off to the island's southern glaciers the a day for snowmobile racing across stunning snowfields, capped off with a dip in the blue lagoon or white water rafting on the fresh water glacial rivers.
