Life was so different.
Played out in the street with an elder sibling from 2. An older girl (i.e. about 7) used to keep an eye on us!
From 8 we went out all day on our bikes with a picnic lunch, and didn't have to come home until tea time. We used to take a map, plan routes and cycle for miles. At 13 this extended to a 9 day cycling trip staying at youth hostels with friends. No mobile phones. At 14 we did a similar trip but first took a train to Devon, literally 100s of miles from home 
10 of us piled into the back of a car on a trip to London. I was in the boot with at least 2 others.
Allowed to walk to the shops at lunch time from year 5, provided we were doing shopping for a teacher. I guess this gave the teachers some control over who went. If you were unlikely to get into trouble you were given 50p to buy something pointless. If you were a PITA they wouldn't need any shopping.
My parents actively encouraged us to disappear off and be at home as little as possible. they didn't ask where we were going they just wanted us gone. The trip we did regularly that shocks me most was a 10 mile bike ride up A roads to a river that had a small weir under a bridge. We'd take a lilo, blow it up when we arrived and spend the day siding down the water rapids over the weir on it. This was when we were primary school age. Pervy men fishing nearby would make comments about us in our swim costumes. I don't know how my parents considered this to be ok.
Aside from the roads being more dangerous life wasn't any safer then. The difference was no social media and much less in the news when bad things happened to kids, so parents didn't worry about it like we do now.
