Hello yes. I have been to Ranwu Lake twice, and the water is the best in April and May, because the rainy season starts in June, when there is a lot of rain in the rainy season, the soil on the mountain will be washed into the lake, and the lake will become turbid. I went there at the end of September, and it was also muddy. It is best to go in April and May, the ultra-blue and ultra-pure beauty. I wish you a pleasant journey and hope to adopt it, thank you.
