Hello chevo hunters.
This solution is more of an extension for the one above. His solution has everything but the collectibles.
After searching online, I found there wasn't any maps for the collectibles, only videos.
I hate following videos, so I created a collectibles map for both areas.
If you're like me and want to find them using a still image, then these are for you.
I Hope it helps.

(There is a chest almost hidden underneath the zoom bar on the bottom right of the map, I have circled the chest to make it easier to see, just a heads up.)
(Some of the collectibles may be off by a few meters, in order to get the map as a one full pic, I had to zoom out, then screenshot it.
This resulted in collectibles not being shown, so then I had to paste the collectibles one by one back onto the maps afterwards.)
((If you mark down, please explain why so I can learn, thank you kindly))
