This walk up Mynydd Mawr Peak has lovely views across Snowdonia and finishes around a lovely lake, yet avoids the crowds.

Location

The walk up Mynydd Mawr Peak starts from the little village of Rhyd-Ddu. You can park along the road opposite the Cwellyn Arms. This pub also makes a great place for an after-walk drink! Alternatively, there’s a direct bus from Caernarfon.

From the main road in Rhyd-Ddu, head past the pub and up left along the road. In roughly 100 metres, take the track on the right heading into the forest. Every now and again you get views of the valley to your right and you’ll see many lovely trees covered in moss.

After almost 1.5km, there’s a small path heading left steeply up the hill. Take this, or if it’s very muddy, you can continue a short distance to a larger trail that then zigzags back to the top of the small path. Follow the track for the next zigzag and you’ll come out of the forest onto the open moorland.

Turn right to walk along the path by the wall, admiring the great views to your left. The path gets gradually steeper and steeper, but soon you’ll be at the top of the first minor peak. It’s a perfect place to have a sit-down and admire the 360-degree view.

When you’re ready, continue onwards, contouring around the mountainous bowl in front of you. Note the dramatic viewpoint of almost vertical cliffs down to the valley below on your left, but don’t get too close!

From here it’s not too far of a walk to the top of Mynydd Mawr. There are similar views at the top, and you can see Snowdon on the opposite side of the valley. Plus on a clear day, you can just about see the sea!

The route down begins the way you came up. However, instead of returning into the forest, take the path leading to the right across the open moor. This small trail leads down past a few old stone cottages to the lake. It can be a bit wet after heavy rain and in places the path is indistinct, but it’s not too far to the lake.

Once you reach the water, turn right to follow the lakeshore to the road. Turn left and head downhill, following the road left around the bend and back to Rhyd-Ddu village. This is the end of the Mynydd Mawr Peak walk.
