5Mount Nyiragongo, Democratic Republic of the Congo
Mount Nyiragongo is one of the most active and dangerous volcanoes in the world, located in the Democratic Republic of the Congo. The volcano is known for its massive lava lake, which is constantly bubbling and shifting. A trek to the summit offers adventurers a close-up view of the molten lava, but the risks are significant. Nyiragongo has erupted multiple times, and its fast-flowing lava can travel at speeds of up to 60 kilometers per hour, making escape nearly impossible if an eruption occurs. Despite the danger, the opportunity to peer into the heart of an active volcano attracts thrill-seekers from around the world.
