Mynydd Rhiw is a wonderfully scenic hike. It's not overly long or strenuous if you set off from the Penmynydd panorama carpark. Walking up through the purple heather lined public footpath with the coast of the peninsula either side of you makes for a picturesque stroll then reaching the summit unlocks views far and wide.

Watch out for overgrown bracken and fern on public footpath but apart from that great hike.
