K-181

K-181 is an exposed reef and cobblestone break with both left and right-hand waves peeling across a shallow rock shelf. The center holds a flat rocky platform that creates well-defined shape during small swell and low tide; during winter swells that reach 20+ feet, waves break farther outside and reform into 100-meter rides. The break is relatively slow and user-friendly for shape, making it popular with longboarders, though the shallow reef demands intermediate-to-advanced skill and constant awareness of rock hazards in the lineup.

The spot was discovered in 1957 by Les Williams and Larry Goodwin during the early Northern Baja exploration era. At that time, the paved highway ended in Ensenada; reaching K-181 required a rough dirt road another 50 kilometers south. The name itself is historical—it refers to the old kilometer-marker system starting from the US border, though those markers have since been reset.

Access is straightforward today via a paved road marked by signage past Punta Cabras. The nearby town of Eréndira provides camping, supplies, and a gathering point for visiting surfers. The spot remains rarely crowded, with autumn and winter offering the most consistent conditions when northwest groundswells combine with east-northeast winds.
