About International Mud Day
International Mud Day takes place on Monday, 29 June 2026, encouraging children, families and early-years settings around the world to get outside and play in the mud. The day champions unstructured outdoor play and the simple, sensory joy of getting gloriously dirty, while celebrating the developmental benefits that come with it.
How to Celebrate International Mud Day
International Mud Day is best enjoyed hands-first, so roll up your sleeves and dive into the mess.
- Build a mud kitchen – Set up old pots, pans and wooden spoons in the garden and let children mix, pour and serve mud pies. Mud kitchens are a favourite in nurseries because they spark imaginative play for hours.
- Make mud pies and sculptures – Squelching mud through your fingers to shape pies, castles and creatures is the heart of the day. There is no wrong way to do it, which is exactly the point.
- Go on a barefoot mud walk – Feeling cool mud underfoot is a wonderful sensory experience. A safe, stone-free patch lets children explore texture in a way shoes never allow.
- Paint with mud – Mix mud to different consistencies and use brushes, sticks or hands to paint on paper, fences or paving. It is natural, free and washes away easily.
- Dig for worms and minibeasts – Combine mud play with a little nature study by gently digging to find worms, beetles and other creatures, then returning them safely to their home.
- Organise a group mud event – Schools, nurseries and community groups can host a shared mud session, which is how the day began and remains its most joyful form.
- Plant something in the mud – Use the muddy ground to sow seeds or seedlings, turning messy play into a small gardening lesson about how things grow.
- Keep it simple at home – You do not need much. A patch of garden, a watering can and some soil are enough to mark the day, even for the youngest toddlers.
What is International Mud Day?
International Mud Day is a global celebration of mud play and outdoor, nature-based learning. It is aimed primarily at young children and the educators and families who care for them, though anyone who enjoys connecting with nature can take part. The day promotes the idea that messy, unstructured play is not just fun but genuinely valuable, helping children develop physically, emotionally and creatively while building a connection to the natural world.
When is International Mud Day?
International Mud Day is celebrated on 29 June every year. In 2026 it falls on a Monday. The date is fixed, so settings and families can plan their muddy festivities for the same day each summer.
The History of International Mud Day
International Mud Day began in 2009, born from a conversation between two early childhood educators from opposite sides of the world. Gillian McAuliffe from Western Australia and Bishnu Bhatta from Nepal met at the World Forum on Early Care and Education in Belfast, where members of the Nature Action Collaborative for Children were discussing how children connect with nature.
Their discussion turned to mud and revealed a striking contrast. Gillian explained that her sandy region of Australia had very little mud at all, while Bishnu’s challenge in Nepal was not a shortage of mud but a shortage of clothes and even soap to wash them afterwards. That exchange sparked an idea that would grow into a worldwide celebration.
Following the forum, Gillian worked with a group of schoolchildren to raise money so that Bishnu could buy extra clothes. Those clothes allowed a group of Nepali orphans to play freely in the mud, and on that same day children in both Nepal and Australia, separated by thousands of miles, spent the day happily covered in muck. From that shared act, International Mud Day was born. It has since spread across continents, from the Netherlands to Nepal to the United States, uniting educators, children and families in a messy, joyful tradition every 29 June.
