Craig Cwm Silyn is a mountain in Snowdonia, North Wales which forms the highest point on the celebrated Nantlle Ridge. The steep northern face is popular with climbers. To the west the Nantlle Ridge continues over Garnedd Goch and ends at Mynydd Graig Goch. To the east the ridge dips down to 515m before rising up to Mynydd Tal-y-mignedd, Trum y Ddysgl, Mynydd Drws-y-coed and ending at Y Garn in Nantlle. The views are extensive, offering a 360-degree panorama.

Garnedd Goch is a top of Craig Cwm Silyn in Snowdonia, north Wales. It is one of the peaks that forms the Nantlle Ridge. It is the third highest point. The summit is strewn with rock debris and has a trig point and a cairn. The panorama includes the Nebo TV mast. The summit is also one of the few places from which the three castles of Criccieth, Harlech and Caernarfon can be seen.

Moel yr Ogof is a summit in Snowdonia. It is a subsidiary summit of Moel Hebog and a sister peak to the lower Moel Lefn. There is an asbestos trial mine located on the summit. A small seam of white asbestos was discovered however insufficient amounts to commercially mine.

St Cynhaearn's Church is a redundant church standing in an isolated position on Ynyscynhaearna, a former island in Llyn (Lake) Ystumllyn, 900 metres (980 yd) south of the village of Pentrefelin, near Criccieth in Gwynedd, Wales.

Ystumllyn is a Grade II* listed house in Criccieth, Wales. Founded in the late-16th-century, and significantly expanded in the early-18th-century, it is remarkable as an "important example" of the vernacular architecture of both periods.

Mynydd Graig Goch (Welsh, 'mountain of the red rock') is the western end peak of the Nantlle Ridge, and is a subsidiary summit of Craig Cwm Silyn. It is also the most westerly 2000 ft peak in Wales. For many years it was excluded from lists of the Welsh 2000 ft mountains due to a spot height of 609 metres (1998') on OS maps. However, this changed in 2008; after years of speculation a group of hillwalkers carried out a precise GPS survey of the peak, measuring the absolute height as 609.75 metres (2000 ft 6 in).

Moel Lefn is a summit in Snowdonia. It is a subsidiary peak of Moel Hebog and a sister peak of Moel yr Ogof. Its summit marks the end of the Hebog ridge. The North Eastern flank of Moel Lefn shows a good example of Columnar jointing within the rhyolite unit that comprises the majority of the mountain. The Beddgelert Forest lies directly to the east, while Cwm Pennant lies to the west. Good views of the Nantlle ridge are observed. There are two tall upright stone cairns on the eastern side of the mountain.

Moel Hebog (Welsh for Bare Hill of the Hawk) is a mountain in Snowdonia, north Wales which dominates the view west from the village of Beddgelert. It gives name to a whole range of peaks in the north-western corner of Snowdonia, which include the Nantlle Ridge and Mynydd Mawr. From that side, Moel Hebog has a rocky face with a distinctive pointed summit, although from other sides, it appears more rounded. The exposed rock means that it is often visited by students of geology. Much of the mountain consists of welded, fiamme rich rhyolitic tuff. It is often climbed from Beddgelert and it can be combined with the nearby mountains of Moel yr Ogof and Moel Lefn for a longer walk. This route, however, does involve some easy scrambling. On Moel yr Ogof can be found Owain Glyndŵr's Cave. The view of Moel Hebog and Llyn Gwynant from the north near Snowdon is one of the most photographed in Snowdonia. A late Bronze Age shield was found in a bog near Moel Hebog in 1784. It is now in the British Museum's collection.
