We set out to hike from the First Water Trailhead to Boulder Canyon, but parking was backed up to the overflow lot. So we decided to drive back to the Massacre Grounds trailhead and there was only one other truck at the trailhead. Beautiful hike with great views of the Supes and some water along the trail. Extremely peaceful with only the sounds of the trickling water and no one else on the trail. Massacre Falls were still running to a mild degree and the views were gorgeous.
