Think back on your childhood, what things do you remember?
Road trips to Italy and France and Spain, mountains, beaches, sunshine, fields of sunflowers, different food and eating outside. Picnics and ice creams on the beach. The different languages.
In the UK trips to the Science Museum and Natural History Museum, the V&A, cinema, different restaurants and cuisines, theatre, concerts. Trips to another part of the UK to visit family we didn't see often.
I can't remember any of the time spent at home or locally except some trips to the park to collect conkers in autumn.
It is a fact that things which are new or unusual experiences stick in your memory in the way day to day life does not, for adults and children. It does widen people's perspective and provide memories and have huge value.
That's not to say lots can't be done locally, too. This week we have been to two beaches, been out for two meals, camped in the garden after looking at stars with the telescope and toasting marshmallows over a fire, done a treasure hunt, made a load of crafts, planted things in the garden, met up with friends locally etc. But will they remember this as much as other trips to new things they haven't seen or done before, or get as much out of it? No. Downtime is valuable and needed, space for imagination (and boredom to make you create something) but so is experiencing different things.
When I was working in a poor country some of the children I worked with had never left their home village. Never been to the beach a few KM from their house, never been into the town just a few more KM away. It makes their world and frame of reference very small.
Of course taking children to new places and to see different things has value. It doesn't need to be all the time or necessarily expensive but to pretend a child who rarely leaves the immediate area where they live will also gain this wider experience is clearly false. They may be happy still, but they will have a small world and miss out on a lot which is a shame as children are full of curiousity and wonder at seeing and experiencing different things.
