Bang Kachao (Phra Pradaeng Green Lung)

Bang Kachao, often referred to as the "Phra Pradaeng Green Lung," covers an area of approximately 11 square kilometers on a river bend south of Bangkok in Samut Prakan Province. It is renowned as one of the largest remaining green spaces in the Bangkok metropolitan area, providing a critical ecological refuge and recreational sanctuary. The area is characterized by lowland tropical forest, mangrove patches, wetlands, canals, and small waterways that sustain a rich diversity of plant and animal species. Historically, Bang Kachao remained largely agricultural and forested even as rapid urbanization transformed surrounding regions. Today, its landscape includes fruit orchards, vegetable farms, and traditional local villages, fostering a blend of nature and cultural heritage. Visitors come to Bang Kachao for biking, walking, birdwatching, and experiencing local markets and temples. The elevated Sri Nakhon Khuean Khan Park is a notable landmark featuring boardwalks, observation towers, and peaceful trails through mangroves and shady groves. This green lung plays an important role in air quality and flood mitigation for Bangkok, making its preservation a key environmental priority. With quiet rural roads rather than paved park paths, Bang Kachao invites outdoor enthusiasts to explore via bicycle or on foot, enjoying both natural and cultural encounters just minutes from Thailand's bustling capital.
