Koh Luang Waterfall there is the limestone waterfalls include seven-levels with different heights and the waterfalls every year. The waterfalls in the Mae Ping National Park had prominent point be known as 'Nam Tok Sam Sri', which comes from the water. Below are colorful seasonal changes to 3 colors. The rainy season, the water becomes to ice tea color because the water will wash sediment down in waterfall. The end of rainy season the color of the waterfall begins to change color the turquoise color. In the dry season the water becomes to the emerald color. Which was the charm attract tourists visit the beauty and touch the freshness of the waterfall.
In summer, I recommend Koh Luang Waterfall and Li District Lamphun Province for you trip. You will be impressed. You will see the water is really clear that made it look like the water of emerald sea of the ocean there it is unbelievable and impressed.
I reminded of the word of -Helen Keller- she said "The best and most beautiful things in the world cannot be seen or even touched, they must be felt with the heart"
