I think its different for everyone.
My kids could not walk to school because we live too far away. They had to catch the bus 11kms to school each day.
I think it would depend on how far the child had to walk and if there were major roads to cross and if there were other children walking the same route.
As you dont live very far from the school i would think that at age 6 he is old enough to manage on his own. When i was a kid we didnt have such strong fears as parents have now and I walked quite a distance to school at age 5. But in those days all the kids walked.
