Terms & Conditions



All visitors to Llechwedd Slate Caverns after dark do so entirely at their own risk.

All event attendees must be aged 18 years and over.



Mystic Worlds reserve the right to cancel an event due to unforeseen circumstances beyond their reasonable control, or if insufficient booking numbers on a particular event make the running of said event unviable. In such cases ticket purchasers will be given the option to book onto another event, or request a full refund. No refunds for other reasons can be given, although if you find you cannot attend we will if possible transfer the ticket(s) to another person(s) providing they are aged 18 and over.



There is a genuine need to observe a variety of guidelines aimed at reducing the risk of personal injury.

Visitors should be aware that there are uneven floors, staircases, low arches and tunnels, furniture, surface water, and other hazards which might be found on site.

As most tours and events will be conducted in low light conditions and often total darkness, visitors are advised to stay together as a group and resist the temptation to wander individually. Moderate intake of alcohol before a Llechwedd night visit may seem natural, but zero in-take would be considered ideal as it could reduce the chances of mishap in dark conditions.



Those with heart conditions and/or a fear of darkness are seriously advised not to register for Llechwedd mine night investigation events.



Visitors are encouraged to wear comfortable shoes and dress in layers for warmth as the mine can be very cold and wet underfoot even during summer months. Hard hats for the mine will be provided and hot drinks will be available for attendees during a break.



The temptation to take random flash photographs should be avoided as it can cause temporary blindness to other visitors. There will be specific periods set aside for flash photography.



Special night access to Llechwedd Caverns has kindly been granted by the management of the venue, please respect the site, its history and contents and act responsibly throughout the event.

By purchasing a ticket you are deemed to have read these Terms & Conditions and agree to abide by them.
