There are two seal colonies near Burnham, one in the mouth of the river on the Foulness sands, and the second in the River Roach.

The seals of the River Roach are remarkable for their ruddy colouring – caused by iron deposits in the mud.

At low tide they bask on the mudbanks – and this is the best time to see them. They may well slide off the mud and swim over to investigate you.
