This tour is highly recommended for elephant lovers, as you can observe them up close! The tour included a brief lecture about elephants, front toenail trimming, feeding, commemorative photos with the elephants, a walk to the river, and bathing them in the river. Most of the participants in my tour were Westerners, and I was the only Asian. Although I was alone, the staff took many photos of me with the elephants, which was a great help. The staff were all kind and spoke easy-to-understand English.
There are small lockers (with keys) in the facility for valuables and luggage. Red shirts, pants with pockets, hats, and sandals are available for rent, so you don't need to bring them. Elephants may suddenly splash water, so it's a good idea to put your smartphone in a waterproof case. Insect repellent is essential, as you will be walking in the forest.
For meals, I had Pad Thai (delicious but quite filling), coconut juice, and bottled mineral water.
The river may seem dirty, but I recommend joining in and helping to bathe the elephants since it's a rare opportunity! There are simple showers at the facility, so you can take a shower on the way back if you are concerned. If you want to use the shower, you may want to bring a towel.
For transportation, I used Grab to go to and from the city. Since the facility is outside the city, it was difficult to catch a car on the way back, and I waited about 15 minutes.
The only downside was that there was no announcement about how to purchase the photos taken by the staff... But overall, it was a lot of fun and a wonderful memory of Chiang Mai!!
