From the lushness of the sea grass around the mangrove roots, the walk changed into a quagmire of mud and what appeared to be anthills. I soon discovered that these muddy mounds which could sometimes be as high as three metres, were the work of mud lobsters that burrowed through the slush to extract rich organic matter. They acted like earthworms by mixing up and aerating the soil. Additionally, the mounds provided habitats for other animals such as crabs, spiders and snakes.
At the end of the boardwalk was Jejawi Tower. I climbed the five-storey structure where four Malay teens were busy taking photos of themselves. All around were spectacular bird’s eye views of coconut trees, the coastal forest in another direction and attap and nipah palms below. I could just spot a small section of the path leading out of the Mangrove Boardwalk through the dense foliage.
This could have been the perfect end to my time on Pulau Ubin Island, but there was still more to explore.
