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.

From the magical summit of Mynydd Mawr, you can see right across the Llŷn Peninsula and out to sea. Bardsey Island, Snowdonia, Anglesey and even the Irish coast – it's all visible. This hill is only 525-feet (160 m) high but it's location makes it tower above the surrounding land and sea, giving it the impression of being much higher.
