Visit Wat Tham Chiang Dao (Chiang Dao)

The Chiang Dao cave temple ('tham' in Thai means 'cave') is the must visit place when you come here. Located 5 kilometers from the city, Wat Tham Chiang Dao also has a pond with a beautiful turquoise water in which swim big fish well fed by the visitors. A covered staircase leads to the entrance to the main caves. One is illuminated and can be visited by yourself without any worry, you just have to pay an entrance fee to pay for electricity. All the other caves open to the public require to hire of a local guide with a petroleum lamp. It is not essential if you have your own lamp but it now seems mandatory (if you trust the signs).

Entrance: 40 THB (to pay for the lighting of the cave)
Guide price for caves with no light: 200 THB
The guides are on site but you can also hire one to visit the whole Chiang Dao area by calling this number provided by TAT: 053 456 442 (I have not tested)
