The difficulty/terrain does not include the way to Tanzania itself
. You'll need a 4WD vehicle to enter
the Park.
At a Picnic Site inside Ngorongoro Crater National Park you'll
find one of the very few places, where you can leave the car.
Use the time to find the cache.
Go the way to the toilets. Some meters behind them you can find the
cache between the roots of the big tree under some stones, covered
with some leaves.
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: are here
frequently, but as a backup have a local contact who will
assist.
