🎂 Birthday parties, Nuclear style!

Swap the usual soft play for a birthday they’ll be talking about long after the cake is gone!

At Nuclear Essex, kids aged 6+ can celebrate with muddy obstacles at Nuclear Wild Forest or take to the trees at Nuclear Adventures, with party options including High Ropes, Zip Trek and, for older children, Knife Throwing.

Perfect for getting them outdoors, off their screens and having a brilliant time with their friends. Our friendly instructors lead the activities, with party spaces available afterwards for food, cake and birthday celebrations 🎈

And at Nuclear Adventures, when you book a party for 10+ participants, the birthday child goes FREE! 🥳

We had a fantastic day today welcoming children to today’s Essex ActivAte funded holiday club. From climbing and exploring to making new friends, it was wonderful to see everyone getting stuck in, building confidence and enjoying the outdoors.

We can’t wait to do it all again next Thursday!

If your child is eligible for the Essex ActivAte Holiday Activities and Food (HAF) programme, there are still funded places available at our holiday club.
