The best time to visit Meo Vac is during the dry season, which runs from October to April, or specifically in late autumn/early winter for the buckwheat flower season.For those who prefer clear skies and comfortable trekking conditions, October to April offers cooler, dry weather. This period is ideal for exploring the Ma Pi Leng Pass and the Dong Van Karst Plateau Geopark, as visibility is generally excellent for enjoying the panoramic mountain views. Couples looking for an active holiday with hiking and scenic drives will find this a superb time.However, if you're keen to witness a unique natural spectacle, late autumn (typically late October to mid-November) is when the buckwheat flowers bloom across the hillsides. This transforms the landscape into a stunning canvas of pink and purple. This season attracts photographers and those seeking a truly memorable cultural experience, as it often coincides with local harvest festivals.
