Elephant Nature Park is a rescue and rehabilitation sanctuary for elephants about 60 kilometres north of Chiang Mai in the Mae Taeng valley. It's one of the most reputable elephant welfare operations in Thailand, and the right place to go if you want to spend time with elephants without contributing to exploitation.
The park is home to over 80 elephants, most rescued from the logging, begging, and trekking industries. Day visits involve walking with the elephants, watching them bathe in the river, and learning about their individual histories from guides. There is no riding, no performances, no hooks. Multi-day volunteering stays are also available. Book well in advance — the park is popular and day visitor numbers are deliberately limited.
