In a bowl or container, combine coconut milk, water, chia seeds, and honey. Adjust the honey to your taste. Stir well to ensure the chia seeds are fully coated. Cover and refrigerate for a few hours, or until the chia seeds have absorbed the liquid and formed a pudding-like consistency.
Peel and chop the mango. Set aside a few pieces for topping. Add the remaining mango and a drizzle of honey to a blender (or use an immersion blender) and blend until smooth. Store in the fridge until ready to assemble.
In a serving cup or jar, layer the mango puree and chia pudding, alternating until you reach the top. Finish with the reserved diced mango for a fresh, colorful topping.
Chill for a bit if desired, then enjoy your refreshing mango chia pudding.
