Take I 84 east from Portland to the exit for Lewis and Clark State Park, park in the parking lot of the park, on the north side, a gravel path goes through the pet exercise area and then parallels the train tracks east bound into the woods. After a rolling 20 minute hike you will come to the first outlying boulders, the Wombat Zone is about a 45 minute hike in.
