Had to look it up. Realised I don't think I have been to that part of the country- must do that one day.
I do it a few times a year - but on the bike. In the summer at high tide this is one of the best places to swim I know of. You can find a whole beach for yourself, even on a bank holiday, if you have a bike (best to park up for free in Birchington and cycle West)
