Overview
Snowdon is blessed with some classic scrambles from the grade one razor ridge of Crib Goch through to the ever popular Clogwyn Y Parson Arete, but most of these routes take the northern approach, and can bear a frightening similarity to a motorway in the summer months.

This route takes a totally different approach, with a more gentle approach from the south using the Watkin Path. Like any Snowdon route the views are weather dependent, but when it's clear are unmatched in Wales.


Approach Park at Bethania (SH 628 507) and take the signposted and well marked Watkin Path. The path takes you up to Cwm Y Lan then follows Afon Cwm Lan to an unmissable collection of old quarry spoil dumps.

Where the Watkin Path turns right (north) head left into the start of Cwm Tregalan. Turn north again as you approach the head of the cwm to see the main cliff and, to its right, a more shattered rock buttress.

On the right hand side of the shattered buttress a narrow gully provides the starting point for the route.


Route The start of the gully is wet, dark and slimy so start off on grippy slabs to the right of the gully before traversing back left where the rock steepens ahead.

Now follow the gully up towards a blocked chimney. Ignore the water-worn route on the left as you approach the chimney and instead move right almost at the chimney base then take on the main buttress ahead.

The buttress gets narrower and initially starts to get easier, but where it suddenly steepens again you can make a descent diagonally down to the left to rejoin the route above the chimney's blocked cap.

Snowdon's atmospheric South Ridge - great views, er,
when you can see them....

Continue up the bed of the couloir for a further 50ft then move slightly left to avoid unstable ground by using a series of easy and grippy holds on the left wall.

After 25 ft you're above the unstable section and can once more rejoin the couloir to the right. A further 30 ft up the couloir a difficult step is again bypassed by a move onto the left wall before rejoining the bed of the couloir.

Time out at the top.

The next 100ft of scrambling follows the rock rib on the left then it's once again back into the couloir itself. The final section beyond the rib eases as you reach the head of the couloir and a shallow bowl.

From here carry on up to the left to meet the main South Ridge of Snowdon not far from the summit


Descent From Snowdon summit the easiest descent is to follow the popular Watkin Path, or alternatively take the South Ridge from Bwlch Main to Bwlch Cwm Llan. From here an abondoned tramway line leads down and left to Cwm Y Llan and the lower section of the Watkin Path.

Caution Scrambling is potentially dangerous and, particularly at the higher grades, requires technical skills and equipment to minimise the risk. We suggest that you take professional instruction or climb with an experienced partner.
