Sixty million years ago, a huge volcanic eruption released a mass of molten basalt. It hardens and compresses as it cools, creating cracks that can be seen today.

This World Heritage Site contains an estimated 37,000 polygonal columns, geometrically so perfect that local legend says they were created by a giant. It is a strong contender for one of the strangest places in the world.
This glossy sea-glass beach in California is the result of littering there over the years. It didn’t stop until the 1960s, but by then the sea was full of everything from old equipment to bottles and cans.

Over time, the waves break everything into colored pebbles, turning the beach into a major tourist attraction. Now, it’s ironically at stake as visitors continue to take the glass home.
The island of Socotra is a place that is unlike any other place. Isolated from the African mainland six million years ago, it feels like a scene from a sci-fi movie. The island is home to incredible and unique plants and trees that you won’t find anywhere else. Two of the most unusual are the Ancient Dragon’s Blood Tree and the Bulbs Bottle Tree. It is definitely one of the most unique places in the world!

Even though Yemen is facing conflict, people are still working hard to protect Socotra’s special environment. It became a UNESCO World Heritage Site in 2008. However, it is still difficult to travel there due to the political problems in the area.
