Psychedelic Salt Mines – Yekaterinburg, Russia
Have you ever rubbed your eyes too hard and entered a world of crazy patterns and shapes? Psychedelic Salt Mines are a bit like that. Go 650 feet below the city to witness a spectrum of surreal swirls – naturally caused by layers of the mineral carnallite to paint colorful patterns across the walls. The site is now only accessible with a government permit, but who wouldn’t love to enter a natural funhouse like this?
