Adventure Parc Snowdonia is home to our world-first surf lagoon. At the heart of the majestic Conwy Valley in North Wales, we’re surrounded by rivers, mountains, woodlands and wildlife of Snowdonia. It is without question one of the most beautiful regions in the UK.
The Adrenaline Indoors facility and the glass-fronted Surf Side Bar, Cafe and Restaurant look out over the waves.
Our breathtaking activities must be seen to be believed – so have a look!
Peek into the many extraordinary experiences we’ve given to people and witness the adventure for yourself.


Test your speed, agility, and dexterity through our multi-level aerial assault course. Including parkour styled features and unique obstacles, start the timer and challenge your rivals to determine who is the ultimate Ninja.


As seen on the beloved 1990s TV shows Ninja Warrior and Gladiators! Our half pipe wall is the final challenge to conquer in our timed Ninja Assault course. At 2.5m tall, commitment and agility are tested to the fullest.


Put your tolerance for heights to the test with our freefall stunt jump platforms. Our 3 platforms range from 3.5 to 6.5m high, landing onto our epic inflatable impact cushion.

Extreme Slides

From the very top to a vertical drop, our extreme slides live up to their name and then some. Take the plunge and head feet-first into the adventure of a lifetime.
Spent a weekend with a group of friends. Fantastic place, efficient and friendly staff. Everything was well organised and clean.
The place has a happy, positive buzz about it.
All the staff were friendly, helpful and encouraging. I would recommend it as an activity for families to do together to get away from screens.
