Best way to create terrain line of sight for trees?

[KlayHaviland]

I am just getting into Unity and was wondering what the best way to create a terrain line of sight for these trees would be. I want the people to be able to see the trees but not see through them obviously.

Welcome!

Use the Terrain LOS occluder. It's designed for trees, you can see into it or out of it, but not through it.
