The flowering takes place from mid-October to mid-December but it is especially the month of November that there are the most flowers (obviously it depends on the weather). They attract a lot of people, the overwhelming majority is Thai. The rest of the year, almost no one comes to visit this remote area. You can climb to the summit by stairs to get the overview of my first photo.
