The place where you can swim between two continents — but there is a catch

In the UNESCO World Heritage Site of Thingvellir in Iceland, there's a crack between two tectonic plates, filled with crystal clear glacial meltwater.

The site is proving one of the most popular dive spots in the world for good reason.

"It is the only place in the world you can be between two continents and go scuba diving at the same time as well," diving instructor Ants Stern said.

Silfra is a fracture in the earth between the North American and Eurasian continents and is constantly undergoing minor changes as the tectonic plates drift apart by around two centimetres a year.

For snorkellers and scuba divers, it's a geological wonder, but there is a catch — the water temperature is near freezing.

"For people back home in Australia, slightly colder, it's between two to four degrees Celsius," Mr Stern said.

Iceland's lava-scarred Rejkjanes Peninsula lies directly on the Mid Atlantic Ridge.

The tectonic fault line can be witnessed above water too. As the plates move away from each other, they tear open fissures in the ground.

Travelling from Europe to North America has never been easier than right here where you can simply walk across a bridge and in a matter of seconds you've crossed from one continent to the other.

Regardless of which side of the globe you'd choose, it is a natural wonder in between that's captivating the crowds.
