This walk takes about 30 minutes. If you park at the hall, then walk out of the car park and turn right.

On your left you will see the dovecote which dates from 1739. If you look through the window on the side you will see that the interior walls are lined with nest holes.

Carry on down the road until the road forks then bear right. You will see a house to your right by some double gates. These gates used to be the main entrance to the house and lead to the front steps. Note the stone carving on the gateposts.

Follow the road as it drops down the hill and across the west front of the house. On your left here you will often see the shire horses relaxing when they are not working at Erddig. This is Erddig Road. Carry on until you come to a kissing gate with a large gate and cattle grid alongside. Go through the gate and you will see a small wooden bridge to your left.

Just over the bridge is the hydraulic ram which was installed in 1899 and used the power of Black Brook to work a pump drawing pure spring water. It worked at a rate of 10,000 gallons per day pumping water up to storage cisterns in the roof of the house. Today it is used to power the fountains in the garden.

Just beyond this is the cylindrical cascade known as the 'Cup and Saucer'. This was constucted under the guidance of the landscape architect William Emes in 1775. Black Brook gathers in the circular basin, falls over the central weir and then exits through a tunnel a few yards away. The design caused the brook to be lowered quickly with the aim of preventing erosion. Black Brook was so named because of its origins in the coal mines.

Now backtrack over the bridge back onto Erddig Road. Walk on just a few more metres and you will see a metal kissing gate on your right. Go through the gate (notice the white entrance gates to your left - this was a second entrance to the house) and follow the path as it bears right and up the hill. At the top of the hill the path bends round to the left. Now follow the path straight on (you will see the house on your right).

You are in the Big Wood which previously used to be the Pleasure Grounds. This area underwent developments and planting until the 1850s, when the grounds were subsumed into woodland. The grounds are accurately depicted in an engraving by Badeslade and Toms of 1739, showing formal tree plantings, horse or deer grazing paddocks, and a spiral path to the summit of Castell-y-Glyn.

Walk to the end of the path and turn right. Follow this path and you will see the east front of Erddig. The gates were made by Davies Bros of Wrexham in the early 1700s. They cost £150 11s 6d and weighed 56 tons. The pond in front is called a ha-ha, used in landscaping to keep stock out but allow unimpeded views.

Turn right at the end of the path and this brings you back to where you started.
