Piedras Negras is another high quality, lefthand reefbreak with powerful, barreling, take-off section from mid to high tide and is only surfed by a friendly local crew, many of whom are bodyboarders. Flawless sparkling tubes breathe down the reef in most small to moderate swells with some S in them. W will make the glassy walls shut down along with dead low tide.
Ilo is a bustling industrial port with one of the largest copper smelters in the country, as well as a copper refinery, only 2km from Piedras Negras, belching out large amounts of air and water pollution. Medium consistency and rarely crowded.
