Most travelers require a visa to enter Tanzania. Visas can be obtained in advance from Tanzanian embassies or consulates in your home country, or you can obtain a visa on arrival at Tanzanian airports and land border crossings. It's recommended to check the visa requirements based on your nationality and make the necessary arrangements beforehand.

Essential items to pack for a Tanzania safari include lightweight and breathable clothing, neutral-colored clothing for wildlife viewing, a wide-brimmed hat, sunscreen, insect repellent, sturdy walking shoes, a good pair of binoculars, a camera with extra batteries and memory cards, and any required medications.

Tanzania offers various safari options to cater to different preferences and budgets. You can choose from classic game drives in 4x4 vehicles, walking safaris, balloon safaris, photographic safaris, cultural safaris, luxury tented camps, lodge safaris, and camping safaris. There are options for group safaris or private/customized safaris.

The best time for a safari in Tanzania is during the dry season, which generally runs from June to October. This period offers excellent wildlife viewing as animals gather around water sources.

However, different parks have different peak seasons, so it's advisable to check specific park recommendations. The Serengeti's wildebeest migration is a major highlight from December to July.
