The temple is located in Ko Kah district, about 15 kilometers South West of Lampang town, a few kilometers West of Highway 1 (Phahon Yothin road).
The quickest and most comfortable way to get there is by private taxi. Most hotels in Lampang will be able to book one for you.
Alternatively you can charter a songthaew, a converted pick up truck with benches in the back. A slower, but fun way to get there is by horse drawn carriage, which should cost around 300 Thai Baht from Lampang town.
To go around the temple and see the local area, charter one of the horse drawn carriages waiting outside of the complex, which should cost around 150 - 200 Thai Baht.
