Route in brief: From Park HQ, study the trail map to identify roads and trails (including Iverson Trail) that lead to Old Haul Road (0.6 miles). Then turn right on Old Haul Road (0.8 miles) → left on Butano Ridge Loop Trail (2.2 miles + 2.5 miles + 2.1 miles) → right on Old Haul Road (3.3 miles) → retrace your steps back to Park HQ (0.6 miles).
Notes: An alternate route that is slightly different: During the early part of the hike, Instead of following Old Haul Road → Butano Ridge Trail, follow Old Haul Road → Portola Trail → Butano Ridge Trail.
