The best time to go to Cerro Colorado is during the spring (September to November) and autumn (March to May) months, when the weather is mild and pleasant for outdoor activities.
During these periods, you'll experience comfortable temperatures, ideal for exploring the archaeological sites and hiking trails without the intense heat of summer or the cooler temperatures of winter. The natural scenery is particularly appealing in spring with blooming flora, and in autumn with changing leaf colors. This allows for a more enjoyable and relaxed pace for sightseeing.
For those interested in hiking and outdoor exploration, spring and autumn provide the most favorable conditions.
