In stark contrast to the bright lights and traffic of Sukhumvit Road, and the grit of countless factories -- all of which are just a stone's throw across the river -- Phra Phradaeng is home to lush forests, parks, streams, overgrown mango plantations, sleepy temples and country homes that blend seamlessly into flower gardens and banana groves. The peninsula has been nicknamed Bangkok's "green lung", and when viewed on a satellite map it appears as an island of forest amid a sea of concrete.
