Parked at Keown Falls Picnic Area. Hiked up the narrower, shadier, steeper south part of the Keown Falls Loop Trail and ate a snack lunch at Keown Falls. Continued up Pinhoti Trail to Keown Falls Observation Deck (views hidden by overgrowth) and on up toward peak, taking a side trail to a good overlook on the east brow before continuing to peak. Another hiker reported that the trail loop on top of Johns Mountain (not including the Pinhoti Trail portion) was overgrown. Returned via Pinhoti Trail to car, noticing that the north part of the Keown Falls Loop Trail (part of Pinhoti Trail) goes much farther north than shown on maps online; only maps posted at trail heads correctly show this.
