Despite its name (from Aruna, the Hindu god of the dawn), the best views of Wat Arun come at sunset - there are several restaurants and coffee shops across the river that make fine viewpoints.
The outstanding feature of Wat Arun is its central prang (a prang is a Khmer-style pagoda), which is about 80 meters tall and symbolizes the legendary Mount Meru, center of the universe. It is possible to climb the prang, using some very steep exterior steps, to two terraces providing fine views.
