Cliffs rocks and stuff

I would like to add cliff ways to the cliff section. Usually cliffs aren’t an area but rather a pretty immense thing that obstructs your way in either direction, What do you think?

Back in school we had to navigate with maps in the forest the maps then usually had markers for big rocks and steep hills/cliffs. These kinds of things are very usefull when you navigate by foot. The clifs were marked by || || || || || || || || || || || || where the _ is the top of the cliff if I remember correctly.

There are tags for steps, inclines and steep inclines. Would those tags suffice?

Not sure what you mean, do you mean that the road/street will be climb up a steep hill?
