Expedition Volcano - In the very heart of Africa, nestled deep within the lush green rainforests of the Democratic Republic of Congo, lies one of the most awe-inspiring yet dangerous volcanoes on planet Earth - the magnificent Mount Nyiragongo. This extraordinary volcano towers over the landscape at over 11,000 feet and contains a massive, seething cauldron of molten lava - the largest continuously active lava lake anywhere in the world. Fiery red-hot lava bubbles and churns within its vast crater, a spellbinding yet ominous sight.
