If you love animals and you would like to do something good, please visit Care For Dogs in Chiang Mai (Hang Dong District) or the Elephant Nature Park in Mae Taeng. The park is not cheap, but you will be rewarded seeing smiling elephants without hooks, chains or fences. They could easily run away, but they love to stay there. In the afternoon you might be able to go swimming in the river with the gray giants and brush their back with a big broom. The park offers day trips or you can stay and volunteer for a while. Something you will never forget. A bit further down behind the park on the same small road some shops offer white-water and bamboo rafting. While bamboo rafting is very slow and relaxed (one could say it's boring), the white-water is a bit more challenging. It is not really that white unless you come after there were heavy rainfalls in the mountains.
