I think we had the most fun in England walking and picnicking and feeding ducks. Simple things but with lovely weather and the green landscape, England is perfect for walking and sitting enjoying the country (well in August it was).
One forest area was set up to encourage children to PLAY and make forts. They left branches and logs in piles out in the woods and kids could build shelters to play in. It was so much fun that all three of us got involved.
