Geoconservation Day at Riddlesdown Quarry
Celebrating International Geodiversity Day 2026
3rd October 2026, 10.00 am – 4.00 pm
Organised by the London Geodiversity Partnership and City of London Corporation
A report of the day’s activities can be downloaded here.
The large Riddlesdown Chalk Quarry south of Croydon in the North Downs is the best location to examine chalk in the London area. Rory Mortimore drew up a conservation plan some years ago and the City of London Corporation, who own the site, has been implementing it ever since. Inevitably vegetation tends to take over, despite employing goats, and rock falls from the cliff face have made the steps unusable. Since 2016 the London Geodiversity Partnership has made the quarry the focus of its geoconservation efforts and will do so again this year. We will be advised and assisted by the City of London rangers. As before there will be an explanation of the geology of the site.
The day will start at 10am and finish about 4pm. We ask you to bring a packed lunch, stout gloves, a hi-vis vest and goggles but spares are available if you do not have them. We suggest you wear old clothes. City of London Corporation will supply tools and tea/coffee.
