RSPB Rainham Marshes Nature Reserve

There are only a few ancient landscapes left in London and this RSPB reserve is one of them.

Bought from the Ministry of Defence in July 2000, its former use as shooting ranges has preserved much of the original medieval land-form and marshland wildlife and is now the largest remaining expanse of wetland bordering the upper reaches of the Thames Estuary.

There is an evolving events and walks programme specially designed for families, with activities for all. All the reserve's paths and boardwalks are family and wheelchair friendly.

The Environment and Education centre provides splendid views across the marshes and River Thames, as well as containing a cafe, shop and classroom. It has been built to the highest environmental standards, with features such as solar panels, rainwater harvesting, natural light and ventilation and a ground source heat exchange system.
