Due to the sensitive nature of the area and the presence of ringed plover and oystercatchers on the ridge, we cannot allow dogs at this event.

Assistance dogs are allowed - if you need to bring an assistance dog please contact chris.wynne@northwaleswildlifetrust.org.uk so we can help reduce the impact of any assistance dogs present while maintaining accessibility for this event. Thank you for helping our conservation efforts.

The ridge is made from large loose stones, walking may be difficult for anyone with mobility issues.
