At the foot of Doi Suthep on Huay Kaew Rd. Look for a large Buddhist shrine (Kruba Srivichai Monument) on your left after travelling past the entrance to Chiang Mai Zoo. Turn left into the market at the back of the shrine, and keep walking up the hill. You will come to the waterfalls after about 5 minutes. The pools at the bottom of the waterfalls are not really big enough for swimming, but are a great place to cool off at the height of summer. During the dry season some of the waterfalls dry up. Head for the high ground and you will still find pools full of fresh water. There are usually quite a few students hanging out there from the nearby university, who will happily practice their English conversational skills with you.
