In Tanzania, it is generally not allowed to walk inside most national parks for safety reasons. This is because many of the animals in these parks are wild and can be dangerous if approached on foot.

However, there are a few exceptions to this rule. For example, some national parks in Tanzania, such as Arusha National Park, Tarangire National park, Lake Manyara, and Mkomazi National Park, offer guided walking safaris with armed rangers, which can provide a unique and exciting way to experience the park's wildlife and natural beauty.

Additionally, some areas adjacent to national parks, such as wildlife conservation areas and game reserves, may allow walking safaris with a licensed guide. These areas may have different rules and regulations than the national parks, so it's important to check with local authorities or a reputable tour operator for more information.

Overall, it's important to prioritize safety when visiting Tanzania's national parks and wildlife areas and to follow the rules and regulations set forth by park authorities to ensure a safe and enjoyable experience for both visitors and wildlife
