As a science teacher I'm always trying to educate :-) cache can be found by most without the clues but go on do some Googling, you might learn something ;-)
Cache is a micro. You will need to bring your own pen.
Close to the main road through Papworth so you will need to keep an eye on young cachers
Wheelchair and buggy friendly.
