13 Real Places That Look Like Straight Up Fantasy Worlds

2. Cave Of Crystals, Naica, Mexico

Okay, either this picture shows a cave of giant crystals in Mexico, or it depicts a troupe of teeny tiny explorers, making their way through a piece of magnified house dust.

The caves contain some of the largest crystals on the planet, some of which are nearly 40 feet in length, weighing 55 tons.

Temperatures can reach a sweltering 58°C with 100% humidity. This means that the surrounding air is actually warmer then the membranes of your lungs so, as you breathe in, moisture condenses against them and begins to fill them. A potential killer.
