A wonderful stretch of downland and chalk coastal bluffs is preserved by the National Trust between Seaford and Eastbourne, on the Sussex coast. It's surrounded by seaside sprawl (and heavy traffic) in the surrounding large towns (Newhaven, Hastings, Bexhill by the Sea, and Brighton).
It reminded me of Pt. Reyes National Seashore, north of San Francisco, California, a place that I knew well years ago, with grazing land combined with spectacular coast scenery.
Clearly, it was a favorite place for walkers, because of the views and open space. On a Saturday morning at 10am, people were streaming in, with knapsacks and walking sticks at hand.
It certainly underscores to me the need for preserving natural places, whether natural gardens or spectacular scenery.
