the trails were designed mostly as bi-directional.
"completely obvious" it most definitely is not!
the signs for the trails will be installed within a week or so...
if you're looking for a "recommended route", most of us typically ride it as follows:
go up the paved path, enter into the second trail on the left after the iron bridge.
at each trail intersection, make a right (or bear right)...this will allow you to hit each loop in the trail system.
have a good ride!
