I am looking for some tree trunk rounds 10"+ of various sizes.

I'm going to make a natural looking path to the trampoline in my backyard so my kids don't have to tiptoe over the mulch under the trees back there.

I'm not wanting to cut them myself, just pick them up and slam some poly on them.

Any recs?

My ChatGPT generated plan:

There's a huge tree that just fell at the house, the corner of Spring Loop and University -- they were cutting it up today, but what you're looking for is sitting by the road waiting to be picked up by probably trash/limb folks. You may drop by and see if you can grab some pieces that you can then have cut into smaller rounds.

Cedar? Oak?

I know a place thats severely overgrown with stuff like this.

Call one of the arborists in town. They're cutting tons of logs all the time and could probably lop off plenty of "cookies" for you and different species as well.
Sam's Tree Service, others.

I have a cedar trunk you can have. No idea if what's you are looking for. Pretty coloring, I would guess about 10-12 inch diameter.

You would need to find someone to cut the thicknesses you would like
