Thorney Island Walk

9 miles (15 km)

Enjoy a coastal circular walk around this beautiful peninsula in Chichester Harbour.
The 9.5 mile 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 Armymilitary baseso 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.

Back in Emsworth you could enjoy some post walk refreshment at the Blue Bell Inn. It's located in a lovely spot on the quay and includes an outdoor terrace where you can enjoy a good quality meal with views over the water. They serve a good selection of drinks and particularly fine fish and chips. You can find them on South Street at postcode PO10 7EG for your sat navs.
