When I visited Prince Edward Island I quickly became aware of the cliffs along the shore. Some of them were steeper than others but I thought that they were rugged, impressive and unforgettable. There were sidewalks and railings to keep people from walking too close to the edge. I took my pictures from a safe distance and these are some of my favorite scenes.
You can see the guard rail in the distance.
This was at the end of a dirt road.
There are more examples here.
