In Kena: Brige of Spirits there are a total of 7 zones, and each of them is divided on the map in a very clear way and you even have fast travel points that will help you move more quickly from one side to another. However, all the collectibles will be very well hidden to make it more difficult for you to discover them. These are: Rot, Hats, Flower Shrines, Spirit Mail, Cursed Chests, and Places of Meditation.
If you want to get 100% of the game (Thanks to getting all the collectibles that we mention in each guide) when you have done it you will be practically at the end of the story of Kena: Bridge of Spirits. Although, its last save point (even if you pass it) allows you to go back to get those collectibles that you lost along the way, so do not have problems in continuing the story.
