Map route for Llanwrthwl horseshoe walk


Llanwrthwl Church, grid ref: SN977638


Starting the walk from the church in Llanwrthwl, follow the minor road that runs down the left-hand side of the graveyard. Follow this road for approximately 2 miles (3.5km) until you reach a fork in the road. Take the right-hand fork and go through the wooden gate. You'll see the National Trust sign for Trembyd mountain on the right.


Follow the gravel track for about 1 mile (1.5km) and you'll see the grassed bridleway cutting up and across the hill on your right, take this bridleway until you reach a dry stone wall and gate at the top. From here, take a right turn and head for the summit of Trembyd mountain.


At the top of Trembyd you'll find a pile of stone that was once a burial cairn. From here, head towards Drum Ddu across the saddle. If you stay to the right-hand side, you'll keep your feet drier and also pass two further cairns. Once across the saddle, cut diagonally left up the hillside until you reach the flatter top and walk along the grass path to the cairn at Drum Ddu. From the Cairn follow the path along the ridge for approximately 440yds (400m) and you'll see a track heading off to the right and downhill towards Rhos Saith Maen. Take this track downhill.


Cross the track that runs over Rhos Saith Maen and follow the path to the bottom of Y Gamriw, then follow the track that cuts up left across the hill to the ruined building at the top. From here, turn right and take the path to the summit that goes from the left-hand side of the building. The summit cairn is on the right, just before the trig point.


From the trig point on Y Gamriw follow the ridge towards Llanwrthwl. You'll pass several cairns on your right along the ridge. As you reach the end of the ridge you need to pick up the zig-zag path that goes down to and through the woodland above Dol-lago Farm. At the farm, follow the signs that take you right and down to the farm track that leads to the road. At the road turn left and then at the T-junction turn right and follow the road back to the church.
