The Wales Coast Path officially opens on 5 May providing an uninterrupted 870 miles of stunning coastline for wildlife enthusiasts to enjoy.
The path encompasses two National Parks, 11 National Nature Reserves and dozens of Sites of Special Scientific Interest (SSSIs).
The idea of a coast path was developed from a desire to build on the economic success of the Pembrokeshire Coast Path National Trail and the Isle of Anglesey Coastal Path. Plans were first unveiled for the project six years ago.
Since then, the path has been developed by the Welsh government in conjunction with the Countryside Council for Wales, 16 local authorities and two national parks.
The whole path will be accessible to walkers and some sections will also be suitable for cyclists, families, pushchairs, people with restricted mobility and horse riders.
