Cau-Cau

Cau-Cau is a small sandy beach break near Ventanas reached by car via Caleta Horcón, then a short drive on a small left road marked “Cau-Cau.” From the end of the access road, you park and walk down a natural eucalyptus path to the shoreline. The beach is described as exposed to swell, and the wave setup can be somewhat inconsistent—reported to break only sometimes—so conditions need to align. When it works, the spot offers both right and left waves and is often described as fun and good quality for beginner wave surfers, with a fast, powerful character. The wave is reported to start around roughly 1.0 to 1.5 meters of swell and can hold up to about 2 meters or more on stronger days. Ride lengths are generally short, but better days can extend rides to around 50 to 150 meters. Tide matters: falling tide is frequently highlighted as best for wave shape, while at the same time the spot is also described as working across all tides. Wind can strongly influence the session; the spot is reported to work with north, west, and south winds, and easterly winds are described as offshore and grooming, but stronger onshore/side winds can add choppiness. Local wind can vary near the shore because high cliffs create wind-shadow effects. Safety is a key consideration. Rocks are present in the surf zone (including near the ends of the beach), and rip currents may form near the rocky areas. Water is cold year-round, so a proper wetsuit (with boots and a leash) is strongly recommended. Rescue availability is reported as no at the spot level, while nearby medical facilities are referenced in Puchuncaví or Quintero; lifeguards are seasonal.
