The best time to visit Sarria, if you're planning to walk the Camino de Santiago, is during the spring (April to June) or autumn (September to October). These months offer the most comfortable walking conditions.During spring, the weather is pleasantly mild, with temperatures typically ranging from 15°C to 20°C. The countryside is lush and green, and you'll experience fewer crowds than in the peak summer months. This makes it ideal for those seeking a more tranquil walking experience.Autumn also provides excellent walking weather, with temperatures similar to spring. The landscape takes on beautiful autumnal colours, and the summer crowds have dispersed, offering a peaceful journey. You'll find that accommodation and services are still readily available, but with a more relaxed atmosphere.If you're not walking the Camino and simply wish to explore Sarria and the surrounding Galician region, late spring and early autumn are still preferable.
