The beach at Holkham is one of the most beautiful in Britain, but it's a long walk from the car park to the actual sand, so we decided to go in the morning after a decent size breakfast, with some snacks to tide us over, but not a full picnic. Personally, I don't really enjoying spending more than about 4 hours on a beach anyway - I get pretty bored - so a half day is perfect for me.
(The beach proper is beyond those dunes.)
Aah, there you go. A bit crowded perhaps, but we have to make these sacrifices.
The kids really enjoyed climbing the dunes. Especially the big one...
