In a large pitcher, combine the orange juice, sparkling water, ground cinnamon, and honey or maple syrup. Stir well until the honey is dissolved and the cinnamon is evenly distributed.
Fill serving glasses with ice cubes.
Pour the cinnamon orange mixture over the ice-filled glasses.
Garnish each drink with orange slices and a cinnamon stick. If desired, add a few mint leaves for a refreshing touch.
