About Us

Hi I’m Lisa. Welcome to Islandeering I’m an islandeer, author and marine conservationist and passionate about sharing what I have learnt from my travels around the islands of the British Isles to help you find an adventure. I started the project 12 years ago after I had one of those light bulb moments and realised the pure magic that islands held for me. After meeting so many people on their island travels who shared my passion and told me that I must share my experiences so that others could do the same I set up Islandeering.com, where we are passionate about promoting responsible travel to our great British islands.

  • Island Summary:

    This uninhabited island, just 450 metres in length, is popular for people staying locally who enjoy exploring the rock pools of the causeway or like visit the remains of a Victorian ship. A former haven for pirates, including the feared mediaeval pirate Alfredo de Marisco who was known as ‘The Nighthawk’, Sully Island is now a Site of Special Scientific Interest and a place to feel free in the vastness and power of the Bristol Channel.

    • A walk on the seafloor of the world’s second largest tidal range
    • Fabulous sculptures and layers in the cliffs
    • Panoramas of several counties and the Bristol Channel islands
    • Getting away from it all a stones throw away from Cardiff
  • Route description:

    On a green light from the RNLI-installed traffic lights the route crosses the slippery rock causeway to the island’s north coast then continues clockwise on the foreshore. The route around the south coast is along the easy island paths above the colourful cliffs. Great views of the Bristol Channel, Welsh coastline and beautiful and colourful rock formations throughout.

  • Getting there:

    From Sully village, between Penarth and Barry, head towards Swanbridge and park in the car park of the Captain’s Wife Inn.
