There are other beaches nearby at Winchelsea, Fairlight Cove & Pett Level which are much more rugged and cliff-like. Particularly fun if the weather's choppy and on those days it may even be worth manufacturing a row when you get there as storming off against the backdrop of turbulent seas, lashing rain & giant waves beating against the cliffs will guarantee a memorable occasion. (NOTE: this is recommended for Winchelsea more so than the other two as it's a bit of a long stomp all the way back to the Ship from Fairlight in particular...)
