There are many temples of sublime beauty & historical significance in the Ampawa area, but one of the most interesting is Wat Bang Kung, which dates back to the Ayutthaya Period.
Wat Bang Kung is famous for the small chapel that is completely enclosed within the roots of a banyan tree called Bot Prok Po. It is almost like the tree itself is the pillars of the temple and that without the roots the chapel would fall down. You can also go inside to pay respect to the Buddha image.
