Hey Fluke, I've got a cat that does that!!
The Beach in the photo is Bracklesham - AKA Bracklesham Bay. It's in West Sussex just a bit beyond Chichester. If you look at the distant shore in between the two kites, that's bits of Hayling Island,Chichester Harbour and Portsmouth/Southsea even furthur out.
It's quite off radar for most people because it doesn't have the usual touristy trappings, piers, amusement parks, butlins etc. There was a Pontins there for years which meant that the beach was always full to bursting in Summer, but that's long gone and ploughed up for a new housing estate - so now this end of the village is quite sleepy, even in peak season.
Great big beach with shallow sands and low low tides - fantastic for swims, beachcombing and late night torch-wanging!!!
My home from home...
Cheers Dave...be lucky...
