A 14 mile Langstone Harbour Waterside Walk can be enjoyed, starting from Ferry Point Eastney, around the whole loop of Langstone Harbour and using the Ferry to return.

This site is protected by the highest level of national and international wildlife designations due to the mudflats, which are rich in food and attract internationally important wildlife collections of wading birds, wildfowl and seabirds. Probably the most significant of these is the Brent Geese that breed in the Arctic region and 20% of the worlds population over-winter in the Solent area. Under the water an excellent array of water-life can also be discovered. Sometimes seals can be spotted in the harbour also attracted by the abundance of food.
