Is this a good place to go trail running?

Yes but not the whole place. I think if you go inside the abandoned village you'll have a better time of it. Otherwise there are places to run but that's off the street, and cars go by fast on the bends

You'd need to look at the trail maps. Some are meant for walking or for families, others are for horseback riding...

There are trails that are flat and wide, as well as more rugged ones.
