Guided options for travelers who'd rather not plan every detail themselves.
Half-day guided tours covering the Grand Palace, Wat Pho and Wat Arun are widely available and useful for understanding the history behind what you're looking at.
Evening street food tours, often through Chinatown or old Bangkok, are a good way to try a wide range of dishes without guessing which stalls are worth it.
Ayutthaya, floating markets and the Maeklong Railway Market are the most common organized day trips, usually including transport and a guide.
