This appendix lists the type of terrain different units can access. The same terrain limitations apply regardless of climate. All unit can use flat terrain or pathways to elevated terrain. No units can walk up the side of ridges without such pathways - only scouts' hawks can fly over them. "Yes" means the unit can enter the terrain, "hide" means it can both enter and actively hide in the terrain, and "no" means the unit cannot enter the terrain. All units that can enter woodland become somewhat hard to spot, but only Hunters can completely disappear in woodland. All units can enter grassland, but only some can attempt to hide in it.
