One of the most popular destinations for a Tanzania Safari is the Ngorongoro Crater. It has green pastures, trees, and wildflowers. People often refer to it as the "Garden of Eden" since it is so beautiful. In 1980, UNESCO designated it a World Heritage site because it features one of the most remarkable natural wonders on Earth: a vast crater that serves as a natural zoo. A massive explosion devastated the Ngorongoro volcano three million years ago. The cone broke apart, leaving behind the most prominent crater in the world, which is an impressive 12 miles wide. This vista is genuinely impressive, and it gets much better when you walk closer to the crater's base and see more and more African vegetation and wildlife. There are a few other extinct volcanoes in the reserve that aren't as impressive but are nevertheless intriguing. Olduvai and Laetoli are two of the most renowned places in the world for studying fossils. There are strict rules governing who may visit Olduvai Valley and access the crater and valley. This is to protect this unique natural wonder.
