Seal Sands

Seal sands is a fragment of what was once a large estuary in the mouth of the river Tees. Most of the former saltmarshes and mud flats have been reclaimed for industrial use. The remaining area is now a National Nature Reserve and is a vital staging post for migrating wading birds. At any time of the year there is something of interest to see and although the wader numbers are not as large as they once were there are still considerable numbers of birds that use the Tees to refuel on their long migrations.
