King Arthur’s Labyrinth – Machynlleth

King Arthur’s Labyrinth is currently open for the 2026 season. It reopened on 25 March 2026 and typically operates daily until early November.

Location and Arrival

This attraction is located at Corris Caverns, near Machynlleth in Mid Wales. It is situated within the Corris Craft Centre site, which offers free all-day parking for visitors.

What to Experience

The adventure is a guided underground storytelling tour that blends Welsh mythology with a unique subterranean setting:

The Boat Journey: Your experience begins by boarding a boat to sail through a “magical” underground waterfall and along a subterranean river.
The Guided Walk: Once off the boat, a hooded Dark Age Boatman guides you on foot through vast caverns and winding tunnels.
Storytelling: Using dramatic light and sound effects, the tour retells ancient legends, including tales of dragons, colossal giants, and King Arthur’s final battle.
Above Ground: The site also features the Welsh Legends Maze, a series of craft workshops, and a cafe.

Duration and Suitability

Time Spent: The Labyrinth tour itself lasts approximately 1 hour to 1 hour 15 minutes. Most visitors spend a total of 2 to 3 hours on-site if they also visit the maze and craft shops.
Who Will Enjoy It: It is ideal for families with school-age children who enjoy drama and adventure, as well as mythology enthusiasts interested in the roots of Welsh legends.
Limitations:
- Mobility: The tour involves a half-mile walk through uneven underground tunnels. It is generally not suitable for those with significant mobility issues or standard wheelchairs.
- Physical Stature: Taller visitors may find some sections uncomfortable due to low ceilings that require stooping.
- Sensory Factors: The environment is dark, damp, and cool, which may be challenging for those prone to claustrophobia or sensitive to the cold.

Best Time to Visit

Weather: Because it is underground, it is a perfect “rainy day” attraction as it remains completely dry. Conversely, it provides a cool escape (constant 8°C) during hot summer days.
Crowds: To find a quieter atmosphere, aim for term-time weekdays or the very first/last tour slots of the day. Pre-booking online is highly recommended during school holidays to guarantee a boat seat.

Unique Appeal

What sets this apart from other local slate mines or caverns is its theatrical focus. While other nearby sites focus on industrial history or adventure trekking, King Arthur’s Labyrinth is specifically designed as an immersive “living storybook” centered on folklore.

Budget and Memberships

Online Discounts: Booking tickets via the official website provides the best prices compared to walk-up rates.
Combined Tickets: You can save money by purchasing joint tickets that include both the Labyrinth and the Welsh Legends Maze.
Concessions: Discounted rates are available for carers (proof required) and occasionally for specific groups like Max Card holders.
Group Rates: Significant discounts are often available for pre-booked groups of 15 or more (excluding August).
Annual Passes: While they do not traditionally offer a standard “annual membership” like a zoo, frequent visitors can sometimes find seasonal offers or 10% discount codes through local accommodation partners.

Visitor Advice

Clothing: It is a constant 8°C (46°F) underground regardless of the weather outside. You must wear a warm coat and sensible, closed-toe footwear with good grip for the damp floors.
Safety: Hard hats are provided and are compulsory for the duration of the tour.
Food: There is an on-site cafe and deli (the Corris Café), but there are also outdoor areas if you prefer to bring your own snacks.
Pets: While dogs cannot go into the Labyrinth (except assistance dogs), they are welcome in the outdoor maze and the craft centre areas.
