The kind of fun that's hard to walk away from

There's a sound a marble makes when it hits the track just right. A satisfying clack, a rush of speed, and then it's gone. And everyone standing around wants to do it again immediately.

Our eight handcrafted marble runs are built from natural wood, rustic and warm, like they've always belonged here. Kids forget everything else exists. Parents find themselves arguing about whose marble went fastest. Nobody walks away after just one go.

No screens. No queues. Just fresh Devon air, the magic of the castle grounds, and the world's most satisfying sound.

Where to find the marble runs

Half the fun is the hunt. The eight marble runs are spread across four areas of the castle grounds, so tracking them all down becomes an adventure all of its own.

Gnome Land — where gnomes roam and marbles roll. Keep your eyes peeled among the toadstools and trails.

Wonder Gardens — find the run nestled among the blooms. A beautiful spot for a very satisfying drop.

Adventure Valley — built for explorers. Race the run, then race to the next one.

Castle Treasures — the grandest setting for the most satisfying sound. Worth saving until last.

One more reason to love a day at Watermouth Castle

The marble runs don't sit in one corner of the castle. They weave right through your whole day, through Gnome Land and the Wonder Gardens, into Adventure Valley and Castle Treasures. They give your family a reason to explore every last corner of the grounds before the day is done.

That's the thing about Watermouth Castle. There's always one more thing to discover. The marble runs just make sure you find it.

Everything you need to know

Marbles are just £3 each. Add one to your basket at checkout when booking online, or pick one up at any till point on arrival.

The eight marble runs are spread across four areas of the castle grounds - Gnome Land, Wonder Gardens, Adventure Valley, and Castle Treasures. Part of the fun is finding them all.

Please use Watermouth Castle marbles only. Outside marbles can block or damage the runs, so we ask that everyone uses the official marbles purchased at the park.

Absolutely. The marble runs are designed for everyone - from toddlers delighted by the movement to adults who will find them genuinely hard to walk away from. Probably the most fun you can have for £3.

Access to the marble runs is included with your castle admission, but each marble is £3 to purchase. You keep your marble at the end of the day as a souvenir of your visit.
