Wentloog Levels

The Wentloog Levels are actually a man-​made area of flat land reclaimed from the sea centuries ago, and drained by a network of reens that offer a valuable habitat for wildlife.
There’s a sea wall along the coastline to prevent the sea from claiming back the land, and you can walk along the sea wall for windswept views across the remote estuary. It’s a million miles from Cardiff Bay and other highly developed parts of the coastline, and at low tide the mudflats are revealed with all their weird and wonderful patterns — alongside areas of salt marsh, offering a popular feeding ground for thousands of birds.
Inevitably you will see the odd bird watcher descending on the area with their binos, but other than that this area is fairly remote and uncrowded.
