The best time to go to Yauya is generally during the dry season, which runs from May to September.
During these months, you'll experience consistently clear skies and comfortable temperatures, making it ideal for exploring the natural beauty and archaeological sites of the Yauya region. The lack of rain means hiking trails are more accessible and views of the Huascarán National Park's peaks are unobstructed. This period is great for those planning active holidays, such as trekking or mountain biking.
For travellers interested in cultural experiences, July is a particularly good month to visit as it often coincides with local festivals and celebrations, offering a deeper insight into the traditions of the Ancash region.
