The best time to go to El Callao is during the dry season, which runs from December to April, particularly around February for the Carnival celebrations.During these months, the weather is more predictable with less rainfall, making it ideal for exploring the town and participating in outdoor activities. February is especially popular due to El Callao's renowned Carnival, a UNESCO-recognized event featuring traditional music, dance, and parades. This period is superb for travelers looking to experience the vibrant local culture and festivities.For those preferring a quieter visit without the Carnival crowds, January, March, and April still offer pleasant weather for sightseeing and enjoying the local gold mining history and natural surroundings.
