Hoo Brook flows down the hillside from Grindon Moor and joins the River Manifold opposite Wetton Mill.
Wetton Mill was a water mill for grinding corn, and the remains of a mill stream, along with a grindstone, may still be seen. The mill is long since disused, but the Tea Room is popular with tourists.
A cave, with several mouths and the centre open to the sky, is a prominent landmark. Immediately downstream from the mill are several swallow holes where the River Manifold begins to flow underground to Ilam.
There is ample parking by the mill, on the site of the old halt, and the cafe is a popular stopping point for walkers using the Manifold Way and the many other rural walks which can incorporate parts of it.
