Stour Estuary

The Stour Estuary is a protected wetland between Essex and Suffolk that stretches from Manningtree to Harwich. The landscape includes saltmarshes, mudflats, and shallow waters that support many animal and plant species throughout the year.

This area was designated as a protected zone to preserve its value for birds and other wildlife. The Stour River had served as an important trade route since the 18th century and its shores reflect long use by local communities.

The estuary ranks among Britain's top 25 bird observation locations, drawing hundreds of volunteer surveyors who conduct winter bird population counts.

The best time to visit is early morning or at low tide when more of the landscape becomes visible. Sturdy footwear is essential since paths lead through wet and boggy areas.

The geological formations at Harwich contain thirty distinct ash layers from the Eocene period, documenting early volcanic activity in southern England.
