Visas & entry
A visitor's account of Santander's beaches, including the camel-rock-formation Playa del Camello, recommends paying real attention to the flag system posted at each one: red means no swimming due to dangerous conditions, yellow calls for caution, and green means it's safe, a system worth checking before getting in the water at any of the city's beaches from Los Peligros to El Sardinero. Her weather note for a June visit was that mornings and evenings ran noticeably breezy and chilly even though afternoons were warm enough for sunbathing, so packing layers mattered more than expected for a coastal summer trip.
