I recommend the Cedar Creek Trail in Petit Jean SP. Short enough to meet your criteria. Most of the trail follows the BSA Trail and makes a loop back to the parking lot. My BSA 12 cache is right on this loop, and the BSA 1 and BSA 2 caches are a short distance off the loop. You could also park at Mather Lodge and hike from there to the falls overlook and pickup the BSA 11 and Canyon View caches. BSA 10 is only a short distance from Mather in the opposite direction along the BSA Trail.
