The iconic former Big Splash water theme park reopens as Coastal PlayGrove, a 4.5-hectare outdoor play area featuring Singapore's tallest outdoor play tower, a classroom by the sea, a nature play garden and water play area. The centrepiece of Coastal PlayGrove is the reconstructed Big Splash Tower, which now houses the Vertical Challenge. Kids can take a scramble up its colourful rope-based obstacles, including stepping pods, hammocks, grip wall and disc swings. Be treated to expansive views of East Coast Park at the top of the tower, then take a thrilling ride down the 7.3-metre and 11.9-metre slides from the third and fourth levels.
