Use a pitcher or punch bowl that holds at least 96 ounces.
Pour 32 ounces apple juice, 32 ounces cranberry juice, and 32 ounces orange juice into the pitcher or bowl.
Stir gently until the juices are fully combined.
Fill each serving glass with crushed ice.
Pour the combined juice mixture over the crushed ice in the glasses.
Garnish each glass with an orange slice, if desired.
If your pitcher or bowl cannot hold all 96 ounces at once, mix the three juices in equal parts in batches and either combine the batches in a larger container or pour each batch over ice to serve until all juice is used.
