The Congo River is the deepest river in the world and the second-longest river in Africa. It flows through the heart of the continent, creating a vital lifeline for people, animals, and plants.

Here are some key facts about this amazing river:
• It's about 2,900 miles (4,700 km) long - that's longer than the distance from New York to California!
• At its deepest point, it plunges over 720 feet (220 meters) deep - taller than a 60-story building!
• The river flows through six countries: Zambia, Angola, Democratic Republic of Congo, Republic of Congo, Central African Republic, and Cameroon.
