Trefor is a peaceful seaside village and the small beack begins with glorious sands running into what eventually becomes a pebbled and shingled area. The beaches here are popular with both holidaymakers and wildlife, with seals often making the shoreline their home. From Trefor, after following the coast for a while you will begin to climb Yr Eifl. Yr Eifl is the tallest of a trio of hills known as The Rivals, an overlooked yet exciting range of hills that make up the backbone of the Llyn Peninsula. Rising to 564 metres above sea level, the Rivals offer rugged walking and great views. Despite some scars left by quarrying activity these hills are full of interest especially with the partly restored Tre'r Ceiri Hill Fort atop one of the summits. As you approach Pistyll you will see another church built by followers of Saint Beuno to give succour for travellers while on their pilgrimage to Bardsey Island. Shortly after leaving Pistill you will soon view Nefyn with its coat of arms of three herrings that reflects how important fishing was to this community. Despite the seemingly short distance of the walk, remember there is considerable ascent to be done and the terrain is hard going in places with large rocks submerged in knee deep heather.
