The view down to Llyn Hywel from Rhinog Fach is a real highlight. This is such a wild place, and the Llyn is placed high up on the mountains in a hollow. Note the famous great slab which dives straight into the water.

The view looking towards Rhinog Fach from above the 'great slab'. Not sure where the photo of the winding gear was taken, but it was not taken here.

It is a steep climb to get here from either the north or south, but easier than Rhinog Fawr from the west. Great views, and the cliffs of the west side side are a playground for rockclimbers.

While some paths might be relatively flat, many trails in the Llyn Cwm Bychan area, even the easier ones, can feature uneven ground, rocky sections, or muddy patches, especially after rain. It's generally recommended to use a baby carrier or backpack for younger children rather than a pushchair to ensure a comfortable and safe experience on most family-friendly routes.
