We took a trip to Southport on the west coast.
I took the kids for a day at the beach.
The tide goes unusually far out leaving these areas of poodles which are shallow enough that I was happy for my kids to paddle in the them without needing particularly close supervision. They do leave the beach very wet and almost muddy. There is a dry area that doesn't appear to get much sea but it is absolutely covered in millions of shards of shells.
Little Miss cut her finger quite deeply on on of the shards so the kids are reluctant to go back to the beach which is a real shame.
