It is possible to get to the temple from anywhere in Thailand by bus. It is easiest to contact a bus company yourself and have them help you with the connections you will need, and there are many bus companies (some are listed below). You can search online via Google, or walk into your nearest bus station and ask them directly. Prices vary depending on the company and type of bus e.g. VIP.
Buses from Bangkok leave from Morchit Bus Station. Buses from Chiang Mai leave from the Arcade Bus Station.
