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.

Garn Boduan is an Iron Age hillfort and hill near Nefyn, on the Llŷn Peninsula in Wales. In a survey in the 1950s the traces of over 170 round houses were identified on this site, and around 100 round houses are still visible on the ground. Between 100 and 400 people may have lived in this fort. The lower stone rampart is the original defence built in the Iron Age. At a later date, perhaps in the 6th/7th century AD, a smaller rampart was built on the eastern side. It is also a UK listed Marilyn.

Pen y Cil is the southern tip of the Llyn Peninsula. The rock here is igneous and there is great climbing on the cliffs below. The Welsh coast path trail runs all around the Llyn which makes a brilliant long run but there are plenty of shorter loops from wherever you happen to start. The high point on Pen y Cil is at 107m which gives good views across the sea and into Snowdonia.
