Dinas Emrys (Welsh for 'Emrys's city') is a rocky and wooded hillock near Beddgelert in Gwynedd, north-west Wales. Rising some 76 m (250 ft) above the floor of the Glaslyn river valley, it overlooks the southern end of Llyn Dinas in Snowdonia. Little remains of the Iron Age hillfort or castle structures that once stood here, save its stone ramparts and the base of a keep [Grid reference SH 60669 49228]. Some believe the castle was erected by Llewelyn the Last to guard the road to the mountain pass of Snowdon.

Sygun Copper Mine is a Victorian copper mine which closed in 1903 but was renovated and reopened by the Amies family as a tourist attraction in 1986, focusing on audio-visual tours of the underground workings. Sygun Copper Mine was once a main supplier of minerals in Wales. It is located about one mile (1.6 km) outside of the village of Beddgelert in the Snowdonia National Park in North Wales.

The Summit railway station is the southern, upper terminus of the Snowdon Mountain Railway, located within yards of the summit of Snowdon. In 2009 a new station building was opened, which was named Hafod Eryri. The line starts in the valley bottom at Llanberis at an altitude of 353 ft (108 m). Summit station stands at 3,493 feet (1,065 m), 68 feet (21 metres) below the summit of the mountain, to which it is connected by a short stepped path.

The A498 is a 16-mile road between Pen-y-Gwryd and Porthmadog in North Wales. At Pen-y-Gwryd, the A4086 Llanberis Pass route bears off to the north. The A498 descends from a 277 m (909 ft.) summit at Pen-y-Gwryd and runs south west through the village of Beddgelert and the Aberglaslyn Pass, where it overlaps the A4085. The A498 then passes through Tremadog, overlapping the A487 for a short length before passing under the Cambrian Coast railway and terminating at Penamser on the A497 (52.9336°N 4.1543°W / 52.9336; -4.1543 (A498 road (southern end))), about a mile west of Porthmadog. At its northern end, the road forms a link via the A4086 with the A5 at Capel Curig, forming a useful holiday route to the Beddgelert/Porthmadog area. At the junctions, the A4086 to Llanberis is the minor road at Pen-y-Gwryd, while the A498 is the minor road at Beddgelert. At Pont Aberglaslyn, the A4085 is the minor road diverging to Penrhyndeudraeth and at Tremadog, the A498 is the major road. The junction west of Tremadog is a roundabout and at Penamser, the A498 is the minor road. There is a steep descent of Nantgwynant and some 1+3⁄4 miles of this is on a substandard, narrow twisting alignment, where larger vehicles have difficulty in passing. There are further substandard sections in the Aberglaslyn Pass and towards Tremadog and coaches have had difficulty passing in this section. The road passes through Beddgelert by way of a sharp right angled bend over a river bridge, not recommended for articulated vehicles. In the Aberglaslyn Pass the trackbed of the Welsh Highland Railway, now being reconstructed, can be seen on the opposite side of the Afon Glaslyn. At its west end, the route crosses the new A487 Porthmadog Bypass at a roundabout west of Tremadog.

Snowdon () or Yr Wyddfa (pronounced [ər ˈʊɨ̞̯ðva] (listen)) is the highest mountain in Wales, at an elevation of 1,085 metres (3,560 ft) above sea level, and the highest point in the British Isles outside the Scottish Highlands. It is located in Snowdonia National Park (Parc Cenedlaethol Eryri) in Gwynedd (historic county of Caernarfonshire). It is the busiest mountain in the United Kingdom and the third most visited attraction in Wales; in 2019 it was visited by 590,984 walkers, with an additional 140,000 people taking the train. It is designated as a national nature reserve for its rare flora and fauna. The rocks that form Snowdon were produced by volcanoes in the Ordovician period, and the massif has been extensively sculpted by glaciation, forming the pyramidal peak of Snowdon and the arêtes of Crib Goch and Y Lliwedd. The cliff faces on Snowdon, including Clogwyn Du'r Arddu, are significant for rock climbing, and the mountain was used by Edmund Hillary in training for the 1953 ascent of Mount Everest. The summit can be reached by a number of paths (there are six main paths) and by the Snowdon Mountain Railway, a rack railway opened in 1896 which carries passengers the 4+3⁄4 miles (7.6 kilometres) from Llanberis to the Summit station. The summit building, called Hafod Eryri, houses a cafe and is open only when the railway is operating; it opened in 2009 to replace one built in the 1930s. The railway generally operates from March to the end of October, with trains running to the summit station from May. The daily running schedule depends on weather and customer demand. Snowdon is one of three mountains climbed as part of the National Three Peaks Challenge.

Llyn Dinas is a lake near Beddgelert, Gwynedd in north Wales. It is formed by the River Glaslyn. Llyn Dinas lies on the valley floor a few miles north of Beddgelert at an altitude of about 55 metres above sea level. It has an area of 60 acres (240,000 m2) and is fairly shallow, with the maximum depth only 10 metres. The lake offers good fishing for salmon and trout. It takes its name from the nearby Dinas Emrys, a rocky and wooded hill just downstream of the lake where the remains of both medieval and older fortifications have been found. A rock near the lake named Carreg yr Eryr (The stone of the eagle) was said in a charter of 1198 to mark the spot where the boundaries of the three cantrefs of Aberconwy, Ardudwy and Arfon met. According to Giraldus Cambrensis an eagle used to perch on it once a week, anticipating battle between the men of the three cantrefs.

Y Lliwedd is a mountain, connected to Snowdon in the Snowdonia National Park, North Wales. Its summit lies 898 metres (2,946 ft) above sea level. The eastern flanks are steep cliffs rising above Glaslyn and Llyn Llydaw. Y Lliwedd is the most conspicuous of the peaks for those who approach Snowdon via the Miners' and Pyg tracks. Few that summit Snowdon continue over to Y Lliwedd as the challenge of Wales' highest peak is enough, leaving Y Lliwedd quiet and peaceful even when queues are forming at the summit of Snowdon. Hikers and mountaineers often pass over Y Lliwedd when walking the Snowdon Horseshoe. The noted British climber George Mallory undertook many of his early climbs here. It was also the site of considerable training activity for the 1953 British Everest Expedition. The north face of Y Lliwedd was explored in the late 19th century and in 1909 was the subject of the first British climbing guide, The Climbs on Lliwedd by J. M. A. Thomson and A. W. Andrews. Two subsidiary peaks of Y Lliwedd are listed as Nuttalls: Lliwedd Bach 818 metres (2,684 ft): SH628532 and Y Lliwedd East Peak 893 metres (2,930 ft): SH623532.

Beddgelert Fault First reported in a Memoir of the British Geological Survey activity ref. Ramsay 1881. It is a SW-NE trending volcanotectonic fault in North Wales that formed part of a graben system within the collapsed Snowdon caldera structure. It was a focus for later felsic intrusions and hydrothermal activity.

Glaslyn (Welsh: Blue lake) is a lake in the Snowdonia National Park in Gwynedd, north-west Wales.

Y Lliwedd East Peak is the twin top of Y Lliwedd in the Snowdonia National Park, North Wales. It is only 5 metres shorter than the main summit of Y Lliwedd. The summit marked by a small pile of stones, the views being similar to Y Lliwedd, except for Gallt y Wenallt being in view.

Garnedd Ugain, often referred to as "Crib-y-Ddysgl", is a pyramidal mountain in Wales that forms part of the Snowdon Massif. It is the second-highest peak in Wales, and lies just under one kilometre north of the summit of Snowdon itself. It is part of the Snowdon Horseshoe route, being linked to Crib Goch via the col at Bwlch Coch, and to Snowdon summit via the col at Bwlch Glas. It is also linked to Cwm Glas to the northeast via a steep arete called Clogwyn y Person, which joins the main Crib y Ddysgl ridge about 500 metres (1,600 feet) east of the summit.

Llechog is a top of Garnedd Ugain on the Snowdon massif in Wales. It is the top of a long crest of cliffs that start in Llanberis and finishes on Garnedd Ugain. The nearby Clogwyn Station is a stop of the Snowdon mountain railway. The summit is a rocky peak sitting out from cliffs which fall steeply down to the Nant Peris valley. The viewpoint is commanding, where the full prominence of Glyder Fawr, Y Garn, Elidir Fawr and Crib Goch can be admired.A second top of the same name can also be found about 1/2 mile to the south-west of Snowdon summit, overlooking Cwm Clogwyn.
