Used leybourne for some swims last year .. they had some water quality issues at the end of the season but am told all ok again now. Will be back there myself in a month or so , or at the one just along the road ( name escapes me ) . Did quite a lot of sea swims on the kent coast at Walpole bay .. huge sea pool there so no worries about getting the tide times spot on .. also a good cafe and hot showers for cafe customers . Will be bringing that into the routine for the occasional Sunday morning from April.
