It is a trove of fossils from the Carboniferous Period about 300 millions years ago.
Our arrival was timed pretty good, we had enough time to make a quick lunch in the trailers before taking a tour.
You can wander around yourself but you don't learn as much and with fossils can sometimes miss them entirely.
Check out this tree trunk in the cliff wall.
She explained one great thing about Joggins is how the erosion of the cliffs if exposing new fossils all the time.
I forget the exact number but as the layers in the cliff go it was about 4000 years of time per foot.
There is also still a lot of scientific studies going on at the cliffs.
