Fantastic family beach

Dec 16th 2020

Perfect family beach.  Lots of space, beautiful sand, lovely view out to sea, sheltered spots around the edge of the beach to make a “base”, some rock pools, a small chine that provides water for moats around sandcastles, lots of space, cafe is decent but not too pricey / pretentious, couple of shops for beach items you’ve forgotten.
Only two important things to note:
- get there reasonably early on busy days - the one car park is reasonable size but once it’s full there’s nowhere else.  We always try to get there by 1000, we’ve always found that OK but wouldn’t leave it much later.
- at the height of high tide there’s hardly any of it - see the OS map high water line - so worth checking before you go.

What did we get wrong?
