This walk includes forest track, views of Snowdonia, waterfalls, tumbling streams and pools, burial chamber, archaeological site.

Leave the train or park the car at Dolwyddelan Station car park. Exit the car park bearing left and left again, crossing the bridge that spans both the Afon Lledr and the Conwy Valley Railway Line. Walk past a few houses then bear right over a concrete bridge onto the forest road. The walk starts here, the track making a moderate climb between the pine trees. At the top of the track you can choose either of two routes (the tracks converge at the head of the valley). Take the left hand fork for the best views and the rocky crag of Carreg Alltrem soon appears to the left. The rock face is popular with climbers and the track affords a good view of their efforts. Continue to the highest point of the track and the view opens out with the waterfall at the far end of the Cwm coming into view. Three homesteads are visible on the valley floor, and a look back down the valley reveals the Carneddau mountains in the distance behind the village of Dolwyddelan.
