Thonburi
Thonburi is the west bank of the Chao Phraya River, opposite the Old Town. Most visitors only cross to see Wat Arun, but there’s more here. Other temples worth a stop include Wat Prayoon with its 60-metre pagoda and turtles in the garden, Wat Kanlayanamit with the largest seated Buddha in Bangkok, and Che Chin Khor with its colourful Chinese pagoda on the riverfront. IconSiam is the big modern attraction, a large riverside mall. Wang Lang Market near Siriraj Hospital has street food and cheap shopping. The floating markets at Khlong Lat Mayom and Taling Chan are further out but good on weekends.
Several rooftop bars have views back across to the Old Town. 342 Bar at Baan Wanglang faces the Grand Palace directly. Three Sixty at Millennium Hilton and SEEN at Avani Riverside are higher up. Tasana Nakorn Terrace at IconSiam works for sunset drinks. For quieter spots, Khlong Bang Luang is a canal community with the Artist’s House and food boats, and Princess Mother Memorial Park is a shaded garden with small museum buildings. The Royal Barges Museum houses ceremonial boats from the Ayutthaya era. Getting around: the Gold Line BTS connects to IconSiam, free shuttle boats run to Sathorn pier, and ferries cover the rest.
