While many might think of Bangkok and nature in the same sentence as being an oxymoron, they probably have never heard of Bang Krachao. Bang Krachao, also known as "the lungs" of Bangkok is a vast area of green space just across the Chao Phraya River from Klong Toey. Originally a settlement for ethnic Burmese Mons, Bang Krachao is made up of orchards and gardens, and a strict local planning code prohibiting high rise buildings and factories has kept the area in a pristine state. Best of all, it doesn't cost a dime to wander around here! The 100 acre Sri Nakhon Kuenkhan Park with its oasis of trees, lakes, and trails is the highlight of the area, as is renting a bicycle and heading out along the raised embankments that run through villages built on wooden stilts.
