Can one see at least some of the trees driving? Is there a Road all the way through? I will have a dog so I can’t take him on the actual trails.

If you want to see the really big ones, you'll need to do about a 45-minute hike loop from the parking lot. Very flat, suitable for small children. Definitely worth stopping, but dogs are not allowed on the trail.

You can see some very large trees, but no noteworthy ones unless you hike in 🙁

We brought our dog and as long as you stay on the pavement trails, which there are several big trees, it's not a problem.
