The best time to travel to Tanzania is from June to October. This is the most popular period for a safari. The vegetation is less dense and animals gather around water sources, making them easier to spot. During these months, all national parks are easy to visit. June to October are the best months for wildlife spotting because it is drier. Temperatures are pleasant and there is little rain. This period is also known for the spectacular river crossings of the Great Migration in the Serengeti. However, prices are quite high then, and it can be crowded due to international holidays.
