Iolo Williams visits his final park of the series and finds himself in the old industrial town of Pontypool in south-east Wales.

The park here was given to the community for leisure by the Hanburys, a family of industrialists. It also happens to be home to thousands of nesting bees and the very rare native crayfish.

Iolo learns how to identify the sex of maybugs, and discovers that deer have been known to use the park and that otters live in the river. Show less
