The first portion of the trail overlaps with the Big Tree Trail, and hikers can opt to add the longer trail to their route to make a loop through the park's higher elevations.
A small sign marks the point where the Old Growth Trail meets up with a forest road that marks a turnaround point, or hikers can opt to head to the park's main parking lot from here.
Retracing their steps, hikers can choose to descend back to the visitor center or may continue on the Big Tree Trail for an added 2.7 miles of distance.
