Wat Arun, also known as the Temple of Dawn, is a famous Buddhist temple in Bangkok, Thailand. Its distinctive spire, encrusted with colorful porcelain, stands out along the Chao Phraya River. Originally built in the 17th century, you can access Wat Arun by ferry across the river and explore its ornate architecture.
I would recommend paying for a guide here because there is so much fascinating history that you would miss out on if simply admiring the temples.
Don't forget to cover up! Women need to cover their shoulders and knees while men need to cover their shoulders. Think long skirts, pants, and shawls or t-shirts. Also I recommend to wear sandals because every temple you enter you have to take off your shoes. So having an easy shoe to remove will keep things moving.
