Piedras Negras is a surf spot located in Ilo, known for its powerful reef break. The area features a friendly local crew, who are mostly bodyboarders. It’s not a super famous spot, which means it doesn't get too crowded, but it's advisable to respect the locals. The vibe is chill, making it a good place for those who want to escape the busier breaks.

The surf here is primarily a left-hand reef break that works best with swells coming from the south or southwest. The waves can get powerful and barreling, especially when the swell is around 4 feet (about 1.2 meters). The optimal conditions arise during mid to high tide, with the best wind coming from the east. More experienced surfers will feel at home here, as it's an expert-level spot. On dead low tide, the waves can shut down, so timing your session is crucial to getting the best ride.

Ilo is an industrial port area, so it has a distinct atmosphere that adds to the surf experience. While the waves might be quality, it’s always a good idea to stay up to date on local conditions before heading out. The irregular reef can catch you off guard, so be prepared if you decide to paddle out.
