Sgyd y Eira

Long, beautiful, muddy walk around Penderyn.

Waterfall country, limestone landscape feature heavy.

Geological wonder (if you are so inclined).

This is the highlight - Sgyd y Eira. You can walk behind it and stay relatively dry.

Featured in Blue Peter with the late, great Caron Keating.

Son #1 is a man transformed away from the evil temptation of wifi and social media.

Even his heavily restricted diet is too much, I sometimes think.
