There's this really cool place in Chiang Mai called the Sticky Waterfall. You can climb the limestone rocks there, and it's quite easy, not slippery. It's like you have gecko hands and feet; you can just stick to the rocks and climb up.

At this waterfall area, if you are interested in visiting the Seven-Colored Fountain or the source of the water, there is a small hiking trail that winds through the trees. As you make your way to the Seven-Colored Fountain, which is now the source of the waterfall, you may be delighted by the melodious sounds of birds singing.

Please be aware that the fountain is sacred place. Ladies, please bring a cloth to cover your shoulders.
