8. Grizzly Man
IMDb Rating: 7.8
We may be boring with all these Werner Herzog’s documentaries on our list of 13 best nature documentaries on YouTube, but the man obviously knows his business. Timothy Treadwell occasionally made journeys to remote parts of Alaska and lived with bears so he could study them. Unfortunately, his passion for bears ended in a tragedy when a rogue bear killed him and his girlfriend. This documentary tells his life story while also taking into consideration the studies he made during his research.
