“La Vaca Gigante” is a prestigious big wave surfing event organized by the sports club ObsessionA2, held at La Cantera-Cueto in Santander, Spain. This invitational event brings together local surfers from Cantabria and international surfers from across Spain, Europe, and beyond. The event’s unique appeal lies in the formidable wave it showcases, which can reach heights of 6 to 8 meters, forming a powerful, pyramid-shaped swell under the right weather conditions. To ensure optimal surfing conditions, the event has a long waiting period, from October to May, with a one-week notice given when conditions are favorable. Attracting up to 10,000 spectators to the cliffs of Cueto, it also enjoys a significant online presence, reaching millions through streaming and social media.
