1. Parking to the Tryfan end of the Ogwen valley gives a nice comfy flat warm up for the legs around Llyn Ogwen, before heading over the stile by the old Roman bridge. There’s multiple choices of path going up, but we tend to keep the drop on our left, which gives great views, a few short scrambling sections, lots of big fun boulders and a couple of scree lines. We find keeping the drop to the left means we can safely navigate this route in any weather conditions.

 

2. More facts: the actual summit of Pen Yr Ole Wen is shit, just a crappy pile of stones in the middle of a football pitch sized flat area. Just off the summit is a tiny stone circle, that gives lovely views on clear days but is also a great shelter from the elements for a quick coffee break in tougher conditions. Wandering northwards brings incredible views down to the tiny lake Lloer, hidden in the cwm.

 

3. The descent down the east side is incredible fun. From the summit we keep the drop to lake Lloer on our left and follow the clear trail that snakes down quickly. The top section is wide open and a dream to stride out, enjoy the view and fill the lungs. Halfway down onwards becomes a mixture of boulders, short drops and more technical trail, all equally good fun. Once we meet the stream from Lloer it’s time to turn right down the valley.

 

4. On reaching the stile and stone wall overlooking Llyn Ogwen there’s a choice between heading off trail across the Pen Yr Ole Wen side of Llyn Ogwen or the faster path down to the main road. The link for the OS Map includes the latter.
