Our friends have been to Sticky Waterfalls several times. It was high on their list of things to show us and I am so glad they did! My children were intrigued by the sticky surface of the falls and scaled the waterfall several times. The cool clean water was a nice reprieve from that heat and it was a nice to be surrounded by nature. When the children tired from climbing the waterfall we enjoyed lounging in the shade of the trees, eating fruit and playing games. It was a nice break from the business of the city. This place is a must see if you are visiting Chiang Mai with children (or without!). It takes about an hour (60km) to reach the falls from Chiang Mai, go north on Route 1001, and if travelling as a group I recommend renting a van or a songthaew for the day.
