This is about everything Chimney Rock has to offer, in both directions:

This includes the new trail, both ways. It also includes the Rock, as in THE rock. Or whatever.
This is a solid ride but it's broken up quite well for anyone who wants to follow it. It starts in Newman's Lane, then cuts across red, and brings you through orange, then into the yellow trails. It hits every trail up there, including the new one. It also gives you the overlook. Most of the yellow stuff you'll get both ways with this loop.
Then it takes you back to the lot, through red. That's roughly halfway. You can grab another bottle or quit. It jumps back in and hits the red trails, so that you've just about done all of them both ways. Then back to the lot, then across the road to blue, where you then do all of them both ways with a small exception.
At that point, you're about 17.5 miles in, and back at the lot. That's 17.5 miles of solid trail, all that CR has to offer. The last 4 miles are the white trails and then behind the ballfield which isn't what I would call the best the park has to offer. Nice enough, but I just tacked it on at the end to make this loop complete.
I left out the trail along the river, on the orange side. Just wasn't in the mood to drop down there today. There are some connectors on the red side that are left out, maybe a few hundred yards worth. In the blue, I don't do much along the stream. Other than that this is about everything. You also get both ways to access the ballfield area - behind the house or through the fence at the top of the hill. This also does not cross the stream from the ballfield trails over to the yellow/orange.
Enjoy!
