On a ridge overlooking the Thames Marshes, Northward Hill includes a lovely bluebell wood. Over 100 pairs of grey herons nest in the trees, with what is one of the UK's largest and most famous colonies of little egrets.
The reserve also includes areas of flat marshes, where lapwings, redshanks, and avocets breed.
There are many miles of trails through to the Heronry Viewpoint and some inspiring views of the Thames valley.
High Halstow NNR is 52 acres of scrub and woodland habitat, dominated by hawthorn scrub and ancient oak woodlands, with regenerating elm woodland. It is part of the larger RSPB Reserve.
