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.

The three stones above Nant Gwytheryn (the Welsh language and heritage centre), perhaps representing the three peaks of Yr Eifl. From here a short detour to the centre can be made for a cake in the cafe.

These grand stones at the Yr Eifl car park are a memorial to the miners who quarried here in the 19th century. This area has a huge industrial history and it can be easy to get lost in the landscapes and forget the incredibly tough conditions these men worked in. The stones stand under the watchful gaze of Yr Eifl.

Close enough to Abersoch to pitch first. Slight slope so pitch sideways, or flatten some sand underneath the tent before pitching. Use the toilet early as the beach gets busy.
