Whether you’re staying in a lodge on the crater’s rim or just visiting for the day, guided game drives give you a chance to explore the crater and its wildlife. You can opt to join a shared game drive or have a private guide who’ll tailor the drive to your interests. You start the day from the top of the crater, where you can gaze over the rim and see the 25 km (15.5 mile) hollow in the Earth stretching before you. Evergreen forest clings to the slopes, and clouds cast rolling shadows over the grassland and pockets of acacia trees. Far below, animals move like tiny ants. As you descend, you begin to make out what they are: antelopes, buffalo, wildebeest and Grant’s and Thomson’s gazelles. Once on the crater floor, your guide’s knowledge of the land comes into play to get you close to animals both common and, if you’re lucky, rare. Sightings of black rhino are far from guaranteed, but you’re in the best place to find them.
