Hiking

Embark on the Llŷn Coastal Path: Aberdaron and Mynydd Mawr Loop, a difficult hike spanning 11.3 miles (18.2 km). You will gain 1350 feet (412 metres) in elevation, requiring about 5 hours and 12 minutes to complete. The trail offers dramatic coastal scenery, with steep cliffs giving way to hidden coves like Porth Meudwy. As you ascend Mynydd Mawr, expect expansive views across the Irish Sea and the rugged Llŷn Peninsula. Keep an eye out for diverse wildlife, from seabirds soaring overhead to seals basking near the shore.

Before you set out, be aware that certain parts of the route might be inaccessible during high tide, so check tide times beforehand. The cliff paths can be narrow, especially as you climb out of Aberdaron, requiring careful footing. This demanding hike calls for good physical fitness and sure-footedness to navigate the varied terrain safely. Plan to start early to allow ample time to complete the loop before dusk.

This route is a highlight within the beautiful Llŷn Area of Outstanding Natural Beauty, showcasing its unique blend of land and sea. Beyond the dramatic cliffs, you will traverse coastal heathland, which bursts with wildflowers in early summer. On clear days, the views from Mynydd Mawr extend all the way to Bardsey Island, adding another layer of natural wonder to your journey.

Aberdaron Beach and Village

Highlight • Viewpoint

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.

View of Bardsey Island from Mynydd Mawr

Highlight • Natural Monument

From the magical summit of Mynydd Mawr, you can see right across the Llŷn Peninsula and out to sea. Bardsey Island, Snowdonia, Anglesey and even the Irish coast – it's all visible.

This hill is only 525-feet (160 m) high but it's location makes it tower above the surrounding land and sea, giving it the impression of being much higher.

Pen y Cil Headland

Highlight • Natural

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.
