A Chao Phraya sunset dinner cruise is a 2-hour tour along the Chao Phraya River in Bangkok that offers dining with views of illuminated landmarks like the Grand Palace and Wat Arun. These cruises are popular for the beautiful sunset scenery and often include a buffet with Thai, international, and seafood options, sometimes with live music or a band. You can choose between "sunset cruises" that end around dusk or dinner cruises that start later for nighttime views, with prices varying based on luxury level.
