One of Bangkok's most photographed temples, perched across the river with striking riverside views.
Wat Arun is famous for its tall central prang (spire) covered in porcelain, visible from across the river — best photographed from the opposite bank around sunset.
Cross the Chao Phraya from the Old City on the regular ferry (a few baht) or reach it by the river express boat stopping nearby.
Entry requires modest dress (shoulders and knees covered); you can climb to the middle platform of the prang for river views.
