Indoor Activities

King Arthur’s Labyrinth in Machyllneth is a popular destination for those wanting to discover more about the local area and the mythos surrounding the labyrinth itself. If taking a boat ride in darkness as an ominous boatman recounts tales of the great king sounds like a great time, you’re going to be in for a treat.

Not too dissimilar from the labyrinth, the Sygun Copper Mine is a fascinating escapade underground into the industrious past of North Wales. The sight of the old mine all lit up is not something you will forget in a hurry and one of the main reasons why it’s earned many tourism awards over the years.

A far gentler pace awaits at the Woollen Mills in Trefriw for those with the patience for tapestry. To say that it’s an art form might not be far from reality as the amount of dedication and intricacy which goes into each piece is not to be undervalued.

If the name Inigo Jones doesn’t sound familiar then his fantastic achievements as one of the original British architects is to be admired. The visionary’s craft within slateworks is plain for all to see at Indigo Jones Slate Works: the perfect day out for those with a love of history.

Located in the revitalised Victoria Dock, Galeri Caernarfon is the cultural heartbeat of the town. The building is home to an independent cinema, art exhibitions, creative workshops and live performances throughout the year. It’s the perfect place to spend a rainy afternoon, with a warm indoor café and remarkable views over the Menai Strait.

Although famed for its towering battlements, Caernarfon Castle also offers excellent indoor exploration. Several museum rooms and reconstructed interiors allow you to step deeper into its medieval history while staying sheltered. Rainy days often mean quieter corridors, giving you a more immersive experience.

Just a short walk from The Black Boy Inn, The Fun Centre is housed inside a huge converted church and offers multi-level soft play, indoor slides, climbing structures and café seating. A perfect option for families with younger children needing to burn off energy on rainy days.

For visitors looking for indoor adventure, the Beacon Climbing Centre is one of the largest and most impressive in North Wales. Suitable for beginners and seasoned climbers alike, it offers roped climbing, bouldering walls and kids’ climbing areas – all safely sheltered from the weather.

A short drive from Caernarfon, the National Slate Museum sits beneath the dramatic Dinorwig quarry. Much of the museum is housed indoors, with enormous Victorian workshops, slate-cutting demonstrations and immersive exhibitions. Entry is free, making it a high-value rainy-day outing.

This indoor museum is home to a fascinating collection of historic aircraft as well as stories of the RAF Mountain Rescue Service. Rainy days often make the indoor exhibits even more atmospheric, especially with views of the coastline through the hangar doors.
