Bang Kachao is an island oasis in Bangkok, referred to as the city’s ‘green lung’. Located in the Chao Phraya river, there are little villages, jungle, Buddhist temples and a lots of lovely vegetation. There is little traffic or commercial development.
The park consists of walkways, alleys, and roads which are large enough to run and allow for traffic. There’s also a series of elevated, wooden, tree-lined paths that are great for cycling and running. If running on these paths, be wary of bikes as the paths are narrow. It’s recommended to run “clockwise” around the park and botanical garden. A run from the pier to the floating market, and a tour of the park is about 15 km (10 miles) total. The run can be prolonged by going further south or exploring the different walkways.
Interesting sites on the island include a floating market, tree house, and several temples. To get there, take BTS Skytrain to Bang Na station. From there, get a quick ฿20 (US$0.60) motorbike taxi to the pier. The boat to the island costs only ฿6 (US$0.18).
