Get the ball rolling

Have you tried our Giant Marble Runs yet? This all new permanent play experience for 2026, features over 100 metres of interactive track spread across eight unique runs. 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.
