The difficulty/terrain does not include the way to Tanzania itself 
.
At a small road in Arusha National Park you'll find one of the very few places, where you can leave the car.
Use the time to find the cache.
Look at the nice Fig Tree that formed an Arch, big enough to drive through with your car. Only a few meters away you'll find the cache 1.2 meters high in a tree close to the road under a stone.
Be aware, that you are in the wild between potentially dangerous animals!
Don't go alone, don't go too far from other people, keep in sight!
You're on your own risk!
Small note on cache maintenance: we are here frequently, but as a backup we have a local contact who will assist.
