Thonburi is a charming residential neighborhood west of the Chao Phraya River, where long-tail boats glide down narrow waterways, or khlongs, lined with wooden houses. On the riverside, the monumental and iconic Wat Arun temple has a towering pagoda and rows of gilded Buddhas. Street-food stalls are scattered throughout the area, serving snacks like grilled sausages and coconut pancakes.
