Place pineapple chunks and peach slices in the blender.
Add coconut water, lime juice, and honey. Blend until smooth.
Strain the mixture into a large pitcher to remove pulp.
Pour in sparkling water and stir gently to combine.
Fill tall glasses with ice cubes.
Pour the mocktail mixture into glasses.
Garnish each glass with mint leaves and pineapple wedges.
Notes
Store leftover mocktail base (without sparkling water) in an airtight container in the fridge for up to 2 days.Add sparkling water just before serving to keep the fizz.For a sweeter drink, add more honey to taste.Replace fresh fruit with frozen for a slushier texture.Skip straining if you prefer a thicker consistency.
