Deep in the heart of the rain forest guests float an ancient river teeming with wild animals, thundering waterfalls and an underground mine. The Congo River is a level, slow-flowing river for inner tubes that is great for a lazy, relaxing float on a hot Texas day. And the best part is you only have to get out when you want to! You can enter the Congo River at various points around the river or from the Raging River tube chute which flows directly into the Congo River.
