The Tessellated pavement near Eaglehawk neck is approximately 300 million years old. The pavement is where a rock surface has been divided by fractures, producing a set of rectangular blocks.
We went the Tessellated pavement when the tide was out, if you don't, the pavement isn't as visible.
Many people go down the stairs to walk on the pavement.
I've taken photos of the way in and then the pavement below.
The last time we visited was in 2015 and you can find the photos [ here ] plus more is written regarding the pavement.
