More than 100 volunteers gathered at Ocho Cascadas beach and the Salto Seco stream in Cabo San Lucas on March 22 for the “Ola Azul 2026” Los Cabos cleanup, hauling away roughly 700 kilos of solid waste in a single morning. The effort, organized by the Los Cabos municipal government, also targeted invasive saltgrass (known locally as pino salado) that traps garbage and degrades the surrounding marine ecosystem.
Mexican Navy and Private Sector Join the Effort
The cleanup brought together personnel from the Mexican Navy, municipal workers, private sector representatives, and community organizations. Volunteers met at the Ocho Cascadas parking lot at 8:00 a.m. and spent several hours pulling trash and invasive vegetation from the beach and the adjacent arroyo.
Ocho Cascadas sits along the Pacific side of Cabo San Lucas, between the downtown tourist zone and the coastline stretching toward El Tule. The beach and its feeder streams are particularly vulnerable to trash buildup because storm runoff channels urban debris down dry arroyos and deposits it at the shoreline. In early February, heavy rains forced black flag closures at both Ocho Cascadas and Playa El Médano after sewage mixed with stormwater reached the coast.
Recurring Pollution at a High-Traffic Stretch of Coast
Beach waste is a persistent problem in Los Cabos. Just weeks after the Ola Azul event, in early April, the municipal public services coordinator Roberto Sandoval Montaño reported that crews removed 21 metric tons of garbage from Ocho Cascadas and El Tule ahead of Semana Santa. That haul required four truck trips from Ocho Cascadas alone, carrying 12 tons, and three more from El Tule with nine tons.
ZOFEMAT (the Federal Maritime Land Zone authority) teams patrol the Los Cabos coastline daily to manage waste and maintain beach infrastructure. But spikes in visitor traffic during spring break and Easter can boost solid waste volumes by as much as 500 percent, according to ZOFEMAT coordinator Rafael Álvarez Munguía.
The Ola Azul 2026 initiative falls under Mexico’s 2025 to 2030 National Beach and Coastal Protection Strategy, a federal framework that coordinates all three levels of government on shoreline conservation. The saltgrass removal component is a newer priority: the invasive plant forms dense thickets along arroyos and beaches, trapping plastic, organic waste, and sediment that eventually washes into the ocean during storms.
Los Cabos municipal authorities said future cleanup events are planned as part of the ongoing strategy, with the next large-scale action expected before the summer rainy season begins in June, according to the Los Cabos municipal government.
