On this page you can find an interactive map of Tanzania to play with.
It shows all the national parks and game reserves, you can see the location of Dar es Salaam and Zanzibar, Serengeti, Ngorongoro...
And you can just make out Kilimanjaro National Park. Just. But since the map is interactive you can cruise around and zoom in as much as you like.
Use the little arrows to move around, or just click on the map and drag it. Double click on any location to centre the map on that location.
The (+) and (-) buttons let you zoom in and out.
If the little overview map in the bottom corner bothers you click on the diagonal arrow there and it'll disappear.
Click on the "Satellite" button to get a real life bird's eye view, and on the "Hybrid" button to have the satellite image overlaid with the map.
Have fun playing with it!
