Get the ball rolling

Pick up a beautifully carved wooden marble when you arrive, and follow it as it twists, turns and tumbles on a journey through Eden’s sprawling gardens.

Our marbles are crafted specially to glide seamlessly through the runs, and can be borrowed for a £5 returnable deposit. At the end of your marble run adventure, you can either return your marble to reclaim your £5 deposit, or keep it ready for your next visit.

Play that inspires curiosity

Demonstrating and inspiring positive action for the planet is at the very heart of Eden’s mission – play is one way to achieve this.

By playing with movement, children are encouraged to test ideas, predict outcomes and problem-solve in real time.

Playing amongst nature helps connect us to its wonders, provoking lifelong curiosity and greater understanding. Research shows that when playing outdoors, children are up to five times more active than playing indoors and use five times as many words.
