A short drive to the west of the Mercado, at the end of a rough road and trail, is a simple remnant of El Valle's pre-Columbian culture called Piedra Pintada, a 15-foot boulder, the underside of which is covered with a bizarre collection of ancient petroglyphs. To get there, turn right at the end of the Avenida Principal and left onto the second road after the bridge, then drive to the end of that road, where a foot path heads to the nearby boulder. Cars left at the trailhead
have been broken into, so don't leave any valuables in your vehicle, and leave the doors unlocked to avoid broken windows.
End of Calle La Pintada, El Valle, 0211, Panama
