Here are the recommendations for ranger.
“Suggested ranger archetypes for the Carrion Crown Adventure Path include Guide, Infiltrator, Skirmisher, and Urban Ranger. Good favored enemies include aberration, animal, construct, humanoid (human), and undead. Rangers with the favored terrains of forest, mountain, swamp, and urban will find their talents most useful during the course of the campaign. See the druid section for suggested animal companions.”
