Jonor School is situated in Sakina, a little of the main Nairobi/ Arusha-Moshi road. First find Sakina supermarket; when you are coming from town you will see a sign board on your right hand side and if you are coming from Ngaramtoni it’s on your left hand side.
From there, take the road 'up', or towards the mountain, for just over a kilometer after which you will be pointed right by another sign.
You are nearly there; click on the little map here to expand (Jonor School is point 'A').
