Arusha may not be known as one of Tanzania's safari powerhouses, but this small, beautiful park has a lot to offer. The closest national park to the airport, you can easily make a day trip to Arusha, which sits in the scenic foothills of Mount Meru. On a game drive through the park, look out for black-and-white colobus, leopard, giraffe and a plethora of plains game. Plus, pods of hippo wallowing in the quiet, pretty lakes. On the clearest of days, you can even see the shimmering, snow-capped peaks of Mount Kilimanjaro.
