Enjoy a coastal walk along this beautiful peninsula in Chichester Harbour. The walk starts from Emsworth, near the train station. From here you can pick up the Sussex Border Path long distance footpath to take you south towards the marina. The waymarked path then takes you along the coast to the village of West Thorney before returning to Emsworth. Along the way there's views of the River Ems and lots of coastal wildlife to look out for. Part of the island is taken up by a British Army military base so it's important to keep to the footpaths. At the southern end of the island you will find a causeway connecting to the RSPB Pilsey Island. The reserve consists of a wide range of coastal habitats including sandflats, mudflats, dunes, shingle and saltmarsh. Look out for nesting oystercatchers and ringed plovers in this area.
To extend your walking in the area you could explore the Chidham peninsula on our Chichester Harbour Walk. It's located just to the east of Thorney Island and includes more nice coastal paths and great views of Bosham Quay and West Itchenor.
You could also head west to Hayling Island and enjoy more lovely coastal paths and nature reserves.
