(1) Starting point - Cwmtillery Car park along side the lower lake. With the lake behind you, you will find two Pit Wheels set in a stone base approximately 100 yards away, these were erected in 1987 to mark the site of the former Cwmtillery Colliery.

(2) Walking north up the lane and over cattle grid, on your right hand side you will see the church of St. Pauls. This was built in 1890 and at a cost £1,250.

(3) On your left hand side is the lower lake, situated in the centre of the valley and surrounded in trees and other plant life making a delightful picnic area.

(4) Following the lane northward and to your right on the hill is a barn, this was called Gwrhyd Bach Barn and some years ago a tudor door was found and now rests with the Abertillery Museum Society.

(5) As you arrive at the top of the lane on your right is Gwrhyd Mawr Farm, it was here that Mari'r Gwrhyd, so called witch lived and placed a curse on the Hendre Farm further up the valley.

(6) Continue north past the entrance to the filtration plant over the stile and follow the footpath, the large lake now on your left is the Cwmtillery Reservoir .

(7) As you pass the top side of the Reservoir you will see remains of a roman road most of which has been washed away by the river Tyleri.

(8) Follow the path for approx 1/4 mile and in the dell stands Hendre Gwyndir Farm. The witch Mari'r once begged for a loaf of bread, only to find barley as well as wheat in her loaf and the curse placed on the cows and pigs stopped milk production and the pigs fell sick.

(9) The stream below Hendre runs red from the iron and steel left in the mines further up the valley.

(10) Walking north you enter the Tyleri Forest known as Nuns Wood and at the northern fringe is a bridge with remains of small tram lines showing how far into the valley mining work was carried out. Having crossed the bridge, turn left and follow the dry stone wall southwards.

(11) The path ahead leads you into steep basin-like hollow called Pant Du. Stopping here and looking across the valley north-east is the working farm of Llan-ty-teri, which is the largest working farm in the valley.

(12) Following the path southwards and over-looking the reservoir are the remains of Ty-Nest Liwelyn Farm built 1670.

(13) As your walk continues southward you will pass the lower lake and an area of reclaimed land, above which you will notice a large cliff. To the south of this was the site of a Methodist Chapel and a row of houses destroyed by a land slide early last century.

(14) Now follow the path down to the main road and back to the car park along side the lake.
