Wilderness Landscape & Natural Heritage
Caernarfon Bay Special Area of Conservation (SAC) is located along the northwest coast of Wales, encompassing marine waters, estuaries, and coastal zones adjacent to the town of Caernarfon and the Isle of Anglesey. The area covers a range of vital habitats including sandbanks, subtidal mudflats, and extensive seaweed communities, which provide essential breeding and feeding grounds for a variety of marine life. The bay supports populations of protected species such as grey seals, bottlenose dolphins, and several types of seabirds including Arctic tern and the Sandwich tern. The coastal waters are also important for migratory fish species and diverse benthic communities. This SAC plays an important role in maintaining the ecological integrity of the Menai Strait and adjacent marine environments. It is part of a network of protected marine areas around the UK and Europe aimed at conserving marine biodiversity under the EU Habitats Directive. Visitors to the area can explore scenic coastal paths offering views of sandy beaches and cliffs, enjoy birdwatching, and participate in marine wildlife watching tours. Nearby historical landmarks such as Caernarfon Castle provide cultural interest, enhancing the visitor appeal. The conservation designation helps balance sustainable recreation with sensitive ecosystem protection, making Caernarfon Bay SAC a significant site for both natural heritage and outdoor enthusiasts.
