I love creating trails through the woods!!!! I've tried three different methods with good and bad results. First was the bush hog. I just drove over anything that I could and shredded up what I ran over. Sometimes I had to back in, and a few times I got into areas that I couldn't go any further. I would go over those trails many times, making them wider, and sometimes, finding turn offs. This worked really good, but it was very destructive on the shredder, the tractor and me. There's just no way to do it this way without destroying stuff.
Next, I used my dozer. I used it for most of my trails, but hav come to doubt the wisdom of using it. The positive side is that it just goes through just about everything. You can really do some exploring and open up the land with it. Unfortunately, it is extremly destructive and the mess it creates takes years to clean up. Just nocking over a tree is fine, but pushing a bunch of them, and piling them up leads to more work to clean it up.
My latest, and best method is to take out the trees with my backhoe, and then drag them to the burn pile with a chain attached to the backhoe. This is a real clean way to do it. The trails look awesome and when your done, your done. No more clean up is needed. In fact, draging those trees along the trail does an amazing job of smoothing out the trails, so there's no addition grading needed.
To lay out a trail, I just sort of look into the woods and work my way through the big trees. I try to save them, and just take out the small ones. Most will wonder along nicely, but sometimes, I make some sharp turns to save a nice tree that I come across. Other times, I'll take out the tree if I have several that are in the way.
If it's warm out, be sure to wear lots of bug spray and carry a can of wasp spray. They can really suprise you, and when you are in the thick brush, there's nowhere to go.
