3. Spend a day with elephants
Chiang Mai is known for its natural mountain habitat and is home to over 30 elephant sanctuaries, and is considered the best place in Thailand to encounter elephants.
Most ethically managed sanctuaries offer activities such as elephant observation and volunteering. Tasks include preparing food, feeding, bathing, and even trekking with elephants through the forest – an unforgettable experience that creates a deep bond with them.
Based on our on-site visits and customer feedback, we recommend the Elephant Nature Park for a nature-based experience and the Bush Camp Chiang Mai for an unforgettable overnight program.

The night bazaar comes alive after 7 p.m. Haggling is common practice. It is advisable to bring sufficient cash, as most transactions are conducted in cash.

After a day full of discoveries, it's time to relax with a spa or massage treatment.
In Chiang Mai you can easily find numerous massage parlors, spas and wellness centers offering various massages, including traditional Thai massages, oil massages, foot massages and much more.
