For a deeply local experience, cross the Chao Praya on a perilous little riverboat and spend the day in the aptly named “green lung of Bangkok”. Rent a bicycle at the pier and explore the perfectly preserved jungle in the natural reserve, or simply cycle through the town to see the many beautiful old houses and exchange passing waves with the smiling locals. Do not miss the market located on a small network of canals, with its amazing fresh produce and cheap Thai food, and cycle to the firefly forest when evening falls. Local maps are available at the pier.
