This image is from my first trip to Etrétat in March/April 2012.
This window had a diameter of approximately 1,50m and was cut in the chalk cliff. A small path led to this place. We’re about 80m above the sea and no fence is between me and the sea. The ground you can see in the im image is the floor I’m standing on. I’m approximately half a meter away from the edge. What a strange feeling!
When I was in this place again in August 2015, only a few remains were visible. Lots of chalk were already eroded.
Take care!

Amazing image … No way could I do that! Makes me feel nervous thinking about it. Well done
🙂
Yup, that was a very strange experience and it took a lot of courage to get there to take the photo (especially, because I used an ultra wide angel lens)
Thank you, Julie!
