  • Island Summary:

    Walking the coast path around Thorney Island is a great way to get away from the otherwise busy coast of West Sussex. Step through the security gates and it feels like another world, full of peace and tranquility. Along the walk there are great views east, across the Thorney Channel to West Wittering, and west, across the Emsworth Channel to Hayling Island. The south of the island has a great beach that is usually deserted and Pilsey Island which is a great spot to watch out for migrating birds. There are also some poignant reminders of the military heritage of this island, with memorials to soldiers of the Special Force soldiers who have lost their lives in recent conflicts, as well as the cemetery in St Nicholas’s Church.

  • Look out for:
    • Ospreys in Autumn at the sandy Pilsey Island nature reserve
    • A warm summer swim off Pilsey Sands
    • Nature-filled and ever-changing views of Chichester Harbour
    • Historic soul of the island in the atmospheric St Nicholas Church
  • Route description:

    The coast path around Thorney Island forms part of the Sussex Border Path. The circular walk starts at Emsworth Yacht Club and crosses the Thorney Road to follow the well-marked coast path onto Prinstead Lane to the village of Prinstead. From the Sea Scouts Hut, the path follows the dyke south through Thornham Marina and Paynes Boatyard to cross the Great Deep and the MoD’s East security gate. The route then hugs the coast until it exits the island at the MoD’s West security gate, and continues to the Emsworth marina.




    (or Prinstead).

  • Getting there:

    Thorney Island is easily accessed by rail (Emsworth Station) where a short walk takes you to the start of the walk. By road there are plenty of public carparks in Emsworth, or for starting at The Deck café, leave Emsworth on the A27, go over the bridge and take the first right after the Sussex Brewery. After 500m turn right onto Thorney Road and right again into Mill Quay. The walk can be undertaken in the opposite direction with limited parking at Prinstead.
