Designed by IMG, the Waterside course at Siam Country Club opened in 2014. The course has hosted several big events including the 2022 Asia Pacific Amateur Championship, and the 2022 Trust Golf Mixed Cup, an Asian Tour and Ladies European Tour joint sanctioned professional event. Water comes into play on several holes, and the challenging greens complexes, and strategically placed bunkers make the Waterside Course an exciting and challenging test of golf.
