Phra Pradaeng in the Chao Phrya River is often called "Bangkok's Lung". It got this nickname for its lack of development and plentiful trees and orchards. The "island" is actually just a peninsula where the Chao Phrya River makes a U turn after flowing through Bangkok's sprawl. Phra Pradaeng has miraculously been spared from the uncontrolled development & industrialization of Bangkok. Some spots on the peninsula are so green and beautiful one would never imagine one is surrounded by the city. The next-best thing to being out in the countryside, Phra Pradaeng has an abundance of coconut trees, fruit orchards and a lazy relaxed vibe that would seem hundreds of miles away from Bangkok. Because of the few cars, the peninsula has become a favorite with Thai cyclists who roam around the island undisturbed by traffic and the dangers of Bangkok streets.
