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.

This stunning mile long sandy beach is at the far end of the Llŷn Peninsula. Its beauty is that it is so close to Aberdaron itself, where there are good places to eat, shops, and car parking. This beach offers breathtaking views out into Cardigan Bay and provides a charming, beautiful atmosphere that is truly magnificent.

Plas y Rhiw is a beautiful Tudor/Georgian manor house owned and cared for by the National Trust. It dates back to the 17th century and stands in a scenic spot on the tip of the Llŷn Peninsula with great vistas out across Cardigan Bay. The manor home is in well-preserved condition and has a charming ornamental garden. Nearby are some quality coastal walks, including a variety of routes to the top of Mynydd y Rhiw, which, at 304 metres, gives you commanding views. It is simply a gem of a place!

Pwllheli is a small town with several cafés, pubs and restaurants, as well as a big supermarket (Asda), long sandy beach, promenade and marina. In terms of tourism, Pwllheli is mostly overshadowed by nearby towns like Abersoch, Criccieth, and Porthmadog. However it offers plenty for people passing through or wanting a place for the night, and I feel the beach is very worthy of a detour!

A scenic single track road with views towards Tre'r Ceiri, the historic and perhaps best-preserved Iron Age hill forts in the UK.
