The Baobab trees, which are native to Madagascar, reach about 100 feet in height and are up to 2,800 years old! They are a legacy of the dense tropical forests that once thrived on Madagascar. The trees did not originally tower in isolation, but stood in dense forest. Over the years, as the country's population grew, the forests were cleared for agriculture, leaving only the baobab trees, which the locals preserved. The best place to see them is called Avenue of the Baobabs.
