Serval Wildlife is a private sanctuary at Usa River, about 25 kilometres east of Arusha on the road toward Moshi and Kilimanjaro.
It houses big cats and other animals that cannot be returned to the wild, most of them rescued from the illegal trade, orphaned or injured beyond the point where release would be survivable. It operates as a conservation and education centre rather than a conventional zoo.
Serval, caracal, leopard and lion are the animals most visitors come to see, and the sanctuary offers a rare chance to observe species that are genuinely difficult to find on safari. Staff talks explain how each animal arrived and what the wider trade in wildlife looks like across Tanzania.
Set among coffee and banana smallholdings in the Meru foothills, it makes an easy half day from Arusha and is a common first or last stop on a northern circuit itinerary, particularly for families or anyone with a spare afternoon before a safari begins.
