You don't have to look hard to find a beach for yourself in Norfolk. We went to one such beach last weekend. It's called Trimmingham and it's just east of Cromer.
First you have to walk across a field and then through a little bit of wood.
Then you have to scramble down a slightly steep slope that I suspect would be somewhat treacherous after heavy rain.
And then you arrive at a beach that you have pretty much to yourself:
I actually witnessed a big clump of the cliff fall away in the distance so I would guess coastal erosion is alive and well here.
Then you collect pebbles and play with them until they inspire you to do something with them.....
