Cnicht Summit

Highlight • Natural Monument

Nicknamed the Welsh Matterhorn, albeit 12,431 feet (3,789 m) lower than its Swiss counterpart, what Cnicht lacks in height it makes up in shapely attractiveness. It is a fantastically pointy, fin-like peak with an irresistible allure. Rising proudly above the hamlet of Croesor, it is the best of the Moelwynion range by far.

Bwlch Glas Pass

Highlight • Natural Monument

The finger stone at Bwlch Glas marks the point at which the Pyg and Miners' Tracks reach the summit ridge and join the Crib Goch, Ranger and Llanberis Paths. Particularly helpful in poor visibility.

Llanberis Pass – Pen-y-Pass Climb

Highlight (Segment) • Climb

Awesome mountain road from Nant Peris in the west to the top of Pen-y-pass in the east. It's a long climb up from Nant Peris or an exciting descent in the other direction. The A4086 follows the Llanberis Pass with historically important rock climbing and bouldering on both sides. Snowdon is to the south and the Glyders to the north.
Café and shop at the car park at the top along with the YHA Pen-y-pass. There is a nice pub in Nant Peris and cafes and shops in Llanberis a bit further down the road,

Bwlch Tryfan (Tryfan Pass)

Highlight • Trail

Bwlch Tryfan is the pass between two of Wales' finest mountains: Tryfan and Glyder Fach. A number of trails meet here and the adventures it gives access to are wonderful.

The South Ridge scramble to Tryfan's airy summit begins here which, as an easy grade one scramble, is the easiest way up the mountain. Head south for Bristly Ridge, a much trickier grade one scramble that leads straight up to Glyder Fach's moonscape summit.

Bwlch Eryl Farchog

Highlight (Segment) • Climb

This is one a the quietest parts of the Carneddau range. For me, it has the most stunning views. If you’re lucky you might get to see the wild ponies.

Excellent connecting ridge between Carnedd Llewellyn and Pen yr Helgi Du. FIne climbing and scrambling routes on the northern side, such as in the Amphitheatre.

The high pass between Tryfan and Glyder Fach is also a crossroads for a number of paths - down to the Ogwen valley, but also up to Tryfan and to Glyder Fach via the Bristly Ridge or the bypass route.

Rainbows on mountains tend to be a mixed blessing as they are a pretty sure sign that you are about to get wet! However from the photographers point of view they can also signal some great light, with sun mixed in with dark moody clouds. This was the view from near the summit of Cnicht - otherwise sometimes called the Welsh Matterhorn due to its pointy appearance from the village of Croesor. To the right of the picture is Moel Hebog which rises steeply above the pictuesque village of Beddgelert.

A fine rocky and in places narrow ridge, and you will often have it all to yourself!

Beautiful hike, too bad it was cloudy at the top. 12.3 km isn't the actual distance you'll be hiking: it's definitely 10 km more because you can't walk a straight line on this path. It's very busy on this trail; there's a queue to reach the top.

Magnificent and dizzying view! However, prefer to go around in the opposite direction to that indicated. The steep slope is very narrow and steep. Easier to go up than to go down.
