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.

Porth Neigwl, or Hell's Mouth, is a large bay on the Llŷn Peninsula in Wales. It's a fantastic place for surfers as it gets fairly large waves, particularly in the winter months. It's close to Abersoch, a major tourist summer spot, but Porth Neigwl seldom gets too busy, making it a great place even in the high season.

Graig Fawr's rocky outcrop towers above the coast path and looks out to sea. It's right next to some seemingly out-of-place sewage treatment works which must be one of few such works with such outstanding views. In this hill's flanks there are hut circles and, a little further north, an Iron Age hillfort.
