Red Hill is also one proposed etymology for the much debated name of Penrith,[1][2] an area called Redhills now lies between the two.

The village of Penruddock itself is situated over limestone which is visible in many places, with craggy outcrops and a limestone pavement on the eastern boundary, and the remains of an ancient lime burning kiln on the north western boundary.

The soil over the limestone is a fairly heavy clay which retains water, with the result that it helps keep vegetation alive during times of drought, but creates very wet conditions for long periods during the winter months.

Penruddock can be reached by car approximately 5.5 miles (8.9 km) west of Penrith, just to the north of the A66 road.

There is also a bus service that runs between Penrith and Keswick that can be caught outside the Herdwick Inn every hour.
