From Po Lam MTR Station, passing Tseung Kwan O Village, you will see a signage at the starting point of Little Hawaii Trail. 5 minutes down the trail, you will encounter a crossroad with four directions: Yau Yue Wan, Tseung Kwan O Village, Au Tau, Tseng Lan Shue. Don't be tempted to go straight towards Tseng Lan Shue (the direction in which you will finish the Little Hawaii Trail). Leave the trail for a moment towards Au Tau and you will see the waterfall.
