Called the Temple of Dawn, Wat Arun is a landmark of the Thonburi area on the banks of the Chao Phraya river. It has to be the most beautiful temple in Bangkok with beautifully decorated spires and its situation with a gorgeous reflection on the river. You should spend at least an hour at the temple and if you got at sunset it is even better when the light hits the spires just right. The spires rise 70 m high and are decorated exquisitely in Chinese porcelain and coloured glass mosaics. You can climb up to the top of the central prang or spire but it is a bit tricky so might we suggest caution.
