Dinas Dinlle is a lovely small coastal hamlet at the mouth of the Menai Straight. It has a large sand and pebble Blue Flag beach called Morfa Dinlle with glorious views towards the Lleyn Peninsula and Llanddwyn Island on Anglesey. The area is also designated as a Site of Special Scientific Interest (SSSI) and part of the land is managed by the RSPB as a Local Nature Reserve. The Reserve is an ideal habitat for nesting lapwings.

before the wider track continues onto the nose/ridge ahead, turn back on yourself and handrail the smaller ridge to your left. take care in poor visibility, it can be steep, slippy, and close to steep drop-offs in places. follow this track to the wall, and then continue down with the wall on your left.

Dinas Dinlle hillfort dates back to the Iron Age and lies above a beautiful beach in North Wales. It may have been built for defences thousands of years ago but it's been used as such far more recently. Atop the hill are Second World War defences as well. Part of the fort has eroded into the sea, giving it a rather spectacular position on the very edge of the land.

Bounded by the sinuous switchbacks of the Nantlle Ridge and the 'Elephant Mountain' of Mynydd Mawr, the Nantlle Valley is one of Snowdonia's quietest and most scenic beauty spots. Characterised by a number of small former slate mining villages and the remains of the industry, it is thought that around 85% of its inhabitants still speak Welsh as their first language.

Gloriously situated on a rugged upland common between the modest summits of Moel Tryfan and Mynydd y Cilgwyn, Y Fron is a peaceful Snowdonian village. There are some fantastic hikes from the village onto the 'Elephant Mountain' of Mynydd Mawr and on the sensational Nantlle Ridge. The village's community centre has a shop, cafe and offers accommodation. See canolfanyfron.org for more information.

In the heart of the secluded Nantlle Valley, Dorothea Quarry's slate veined pits and deep, dark pools silently remind all who wander by of the region's mining heritage. Six pits remain, the deepest dropping 348 feet (106 m) below the surface. Quarrying ended here in 1970. The pits constantly needed pumping in order for them to stay dry. In 1904, a Cornish beam engine was installed, which today is a Grade I-listed building. Its operation ceased in 1951, when it was replaced by electrical pumps.

You are likely to have heard of the Nantlle (pronounced Nant-lee) Ridge, a sinuous and wonderful traverse of medium-sized peaks to the south west of the Snowdon Massif. The ridge is named after this little village to the north west, which has its own little llyn (lake) and a proud slate mining heritage. The Nantlle Valley is beautifully secluded and undoubtedly scenic. It's thought that around 85% of its population still speak Welsh as their first language. Accommodation can be sought at Trigonos B&B.
