This walk takes in the three key summits in the Glyders - Glyder Fach, Glyder Fawr and Tryfan. It also includes the Y Gribin ridge with its excellent opportunuties for scrambling. Do choose a fine day as the views are spectacular throughout.
Calculated time is computed with the distance, the height difference, and an average speed of 2.2 mph. For an intermediate walker, this time includes small breaks.
(D/A)The walk starts at Idwal Cottage (grid ref. SH649603) where there is a youth hostel at the head of Llyn Ogwen. A well-constructed footpath leads in less than a mile to the mountain lake of Llyn Idwal, a favourite spot for rock climbers because of the Idwal Slabs at the end of the lake. This route branches off left (grid ref. SH646596) before you get to the Idwal Slabs, about half way along the path to the left of the lake, and follows up a steep, pathless stretch of mountainside to reach the crest of the ridge called Y Gribyn where a clearer path can be found. Tryfan now appears as the backdrop to the view to the west on the other side of the ridge with another wildly situated mountain lake, Llyn Bochlwyd, below, also on your left.
(1)Now follow the upwards ridge ahead, which becomes steeper and rockier in places as height is gained. When the top of the ridge is reached (grid ref. SH650582), the going becomes easier. Glyder Fawr is the first summit to be reached on this walk and is now less than a kilometre to the south west, the top being noticeable for its weird spiky rock formations. If visibility allows, Glyder Fach will be seen along the ridge in the distance along with the Snowdon horseshoe to the south west and the Carneddau to the north east.
(2)After reaching Glyder Fawr you need to retrace your steps along the main ridge path towards Glyder Fach passing the point where you exited from the Gribin ridge. An interesting digression shortly before Glyder Fach is the spiky rock formation known as Castell y Gwynt or Castle of the Winds, off the path to the left. Its scrambling opportunities are an optional extra to the main route.
(3)Glyder Fach is one of the few mountains where the use of both hands and feet is required to reach the very top, the highest of the pile of rocks and boulders being a horizontal rock rather like a miniature bridge. It is also advisable to use hands as well as feet on the way up to the top as this makes it easier to move across the gaps between boulders while minimising the risk of an unpleasant loss of footing. The Cantilever Stone is nearby and is a popular photo stop. The towering, rocky hulk of Tryfan dominates the view to the left (slightly east of north). From here, it appears to some to be insurmountable; but there is a clear enough path to the top which comes later in the walk.
(4)The most direct approach to Tryfan from here, Bristly Ridge, is more easily done in ascent than descent and therefore this route takes the easier option of following the main ridge path down to meet up with the Miners' Track which then leads bears left (grid ref. SH667582), down and up again to Bwlch Tryfan (grid ref. SH661588).
(5)From Bwlch Tryfan, the ascent of Tryfan starts in earnest. There is one point near the summit where there is a "bad step" but many walkers do not even notice it. From the top you can look down on Llyn Ogwen and across to the Carneddau as well as back across to the Glyders and Y Garn.
(6)For the descent route, the easiest way is to reverse the route back down to Bwlch Tryfan where a clear path leads down past Llyn Bochlwyd (sometimes known as Lake Australia because of its shape) and back down to the start point of the walk.

In my estimation, the weird and wonderful rock formations of Glyder Fach, Glyder Fawr and Tryfan, along with their altitude, make them rank among la creme de la creme of the Welsh mountains. This walk route includes all three, each of them having the Welsh equivalent of Munro status, that is, they top three thousand feet. For those who like scrambling, there are a number of opportunities during the walk.

Llyn Idwal lies in a spectacular location under the Glyder Mountains in Snowdonia. This walk provides a mountain experience without too much effort walking through a rocky amphitheatre in the mountains.
This challenging route to the summit of Tryfan is one the great walks and scrambles of Snowdonia. Starting from the Ogwen Valley, much of the ascent up Tryfan's north ridge involves the use of hands. In winter this route takes on a different character when ice and snow are present and should only be attempted by those experienced in winter mountaineering.
This Snowdonia walk starts from Pen-y-Pass and uses the Pyg Track towards the summit of Snowdon. The route then crosses Y Lliwedd to pick up the Miner's Track for the return to the start. Good navigational skills are essential when leaving Snowdon and because of this, the walk is recommended for experienced walkers only.
The Carneddau in Snowdonia provide for some tough walking and this route is no exception. Good navigational and map reading skills are required in the early stages of the route.
Snowdon, the highest mountain in Wales, is the objective of this walk. This route is the easiest way to Snowdon's summit. Starting in Llanberis, it must be remembered this walk is a serious mountain expedition so you should go fully prepared.
A Snowdonia walk that explores two less frequented summits from Llanberis. The walk offers grandstand views over many of the high peaks of Snowdonia and is more challenging than first impressions might suggest.
The minor Snowdonia summit of Crimpiau provides an excellent walk from Capel Curig. The route crosses quite mountainous terrain and the view down Llyn Crafnant is one of the great panoramas in the area. Do make sure you are suitably equipped for this walk.
This walk on the eastern side of the Carneddau mountains in Snowdonia offers a sense of solitude and excellent mountain scenery. The route is generally easy to follow although careful navigation is needed on the section from Dulyn Reservoir back to the start.
