Located in a rural corner of Ubin Island off mainland Singapore, the Chek Java Wetland, which is accessible by ferry, covers an area of 100 hectares, and is teeming with wildlife and biodiversity. Highlights include the boardwalk that runs 1 km along the coast and is ideal for walking and watching the rich flora and sea life, and the 20-meter-high observation tower that gives you the opportunity to watch birds.
