What to do in Bangkok

Bangkok is far more than its reputation. Visit stunning temples like Wat Arun and the Grand Palace, explore floating markets, hunt street food in Chinatown, or unwind in traditional spas. The Chao Phraya River is your best ally for getting around and soaking up the city. A week gives you solid time to know Bangkok well and squeeze in a day trip to Ayutthaya or nearby beaches.
