11 kms from Doi Mae Ukor (Bua Tong Field) to the great waterfall, Mae Surin. Road is narrow, steep and tortuous. On the top of hill which you may park and walk a bit to appreciate the beauty of the waterfall. The other spot, you have to walk down to the lowest level about 3 kms or 1 hour. You will so exhausted about 3 hours on trekking up and down like I did. However, it's worth when you stand as I did and came up with these photos.
Only one level, it falls from the one-meter cliff. Tide is very strong, but you can swim at the lower part of the fall.
