Visited Stevns Klint in September 2017. The place is very popular among locals, who seemingly spent the whole day there walking along the coastline and some attraction points like COld War Museum.
Also spent around 30 minutes trying to find any fossil on the beach below Stevns Klint but without success.
Information leaflets provide indication of where very thin K/T layer is located.
For ordinary person it's difficult to fully understand the scientific importance of this layer, but this is an integral part of WH sites, which cover so many different aspects of history, nature and culture, that they can't all be stunning lookers. You'd never know more details and information about extinction event and mysterious disappearance of the dinosaurs from the Earth. In overall, the place is quite a fun to explore and the sea views are good.
As suggested by Clyde, next time will go to quarry Holtug Kridtbrud in order to find fossil.
