We have a growing number of outdoor nurseries in Scotland. To give you a flavour, have a look at this news clip (Oct 09) and this news clip (Jan 10) of Woodlands Outdoor Kindergarten which is based in Glasgow. Notice how grubby the outdoor suits are! Childhood is meant to be messy.
The Secret Garden is a nomadic outdoor nursery with a unique curriculum.
Finally Mindstretchers, a very established education consultancy set up two nature kindergartens. They organise courses and visits too!
