There are plenty of deep steps at the start and us oldies decided to avoid them on the way back.

Take time to visit The Maritime Museum and stop at their coffee shop whilst you're there before you carry on on your journey along The Welsh Coastal Path or just visit as part of a morw local stroll or visit to the beach.

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.

Aberdaron is a very beautiful but busy coastal village that has an ancient pedigree. In days gone by this fishing village used to be the last stop for pilgrims on the way to nearby Ynys Enlli, or Bardsey Island. Now it is a quaint but vibrant tourist hub. There's plenty to do at Aberdaron, the surrounding headland has miles of sandy beaches and secret coves to explore. There is also hiking galore as the Wales Coastal Path passes through here and being out on a headland there are a myriad of other hikes. Also let's not forget the one mile long sandy beach here which is one of the finest in Wales.

Nefyn is a beautiful little north coast seaside village with harbour, museum and a graceful sandy crescent beach. The Llyn Maritime Museum tells the story of the peninsula’s often stormy relationship with the sea.
