The best time to visit Santa Bárbara is during the dry season, which typically runs from December to March.
During these months, you'll experience more sunshine and less rainfall, making it ideal for exploring the town and its surrounding natural beauty. The weather is generally warm and pleasant, great for outdoor activities like hiking or visiting coffee plantations.
For travellers planning to enjoy the regional festivals, visiting in late January or early February is recommended as this is when the "Carnaval de Negros y Blancos" (Black and White Carnival) takes place in nearby Pasto, a major cultural event. While Santa Bárbara doesn't host its own carnival, its proximity to Pasto makes it a convenient base for experiencing the festivities without being in the midst of the main crowds.
Couples looking for a peaceful getaway will appreciate the dry season's calm days, allowing for relaxed strolls through the town's streets and enjoying the scenic views of the Nariño landscape.
