Arenig Fawr, the objective of this walk, provides an excellent 7mile day in the mountains. Rising to 854m its relatively solitary position means that in good weather the views are superb. Good mountain clothing is required as well as OS map OL18 with a good compass.
Park at a large area of waste ground (Sat Nav LL23 7PA). After parking continue along the lane in an easterly direction for a mile passing a number of houses on the way. Just after Pant-yr-Hedydd take the rising grassy track that initially heads south west.
The track turns to head southeast and levels off at Llyn Arenig Fawr. Continue on the track until you see a small building near the dam outflow. Turn right down a path and through a gate at the rear of this building. Cross the outflow stream and continue along the path that rises along the crest of ridge with the reservoir on your right and you soon reach a fence. Cross this and continue in the same direction until a fence is approached at an acute angle. Cross this fence where convenient and make sure you follow the path, which in places is less than obvious.
This path does not climb directly onto the ridge ahead but trends left and contours across the southeastern flank of Arenig Fawr gradually climbing. As you get nearer to the area beneath the summit look out for a solitary post located up the slope. This marks the best route of ascent and soon you will reach the summit. On the summit there is a wind shelter and a memorial to a bomber crew that crashed here during World War II. The view is superb.
Arenig Fawr has a number of clearly defined ridges and it is important for the purposes of this route to choose the right one! The easiest method of navigation is to leave the summit in a northeasterly direction following the fence which should be on your left. There is a path and you need to continue beside the fence for nearly a mile. Ahead lie some fairly severe crags and these must be avoided. The safest way to do this is to cross the fence line and drop down into the wide cwm on your left.
The path becomes less obvious however the key to this descent is to locate the stream and follow it down towards the valley below. There is a path (of sorts) that leads all the way down to a grassy track that runs parallel to the lane. Once this is reached turn right and you will be back at the parking area in a few minutes.
