Plan on roughly a dozen water crossings. Sandy banks, brush and slickrock make the walk slower than the small elevation change suggests, and the informal tread can shift as floods and beaver dams alter the wash. Four tributaries enter from the left at about 1.2, 1.7, 2.2 and 2.7 miles downstream. Slickrock shelves spill the creek into a large pool in the lower canyon; that water-and-stone view is the standout photo stop.
Courthouse Wash is an active drainage with unpredictable flow. Don’t enter when flooding threatens. Dogs aren’t allowed in the backcountry.
