In a large pitcher, combine the pineapple juice, coconut water, light rum, lime juice, and simple syrup. Stir well to mix all the ingredients together.
Taste the mixture and adjust the sweetness by adding more simple syrup if desired.
Just before serving, add the club soda to the pitcher and gently stir to combine.
Fill glasses with ice and pour the punch over the ice.
Garnish each glass with fresh pineapple slices, lime wedges, and mint leaves.
Serve immediately and enjoy your refreshing tropical drink!
