Walking up Cwm Tryfan valley is lovely, in short a boulder field with streams and beautiful natural flora everywhere.

The mid afternoon light on the mountain summit can be spectacular on the right day from the bottom of Bristly Ridge.

Tryfan South Face Trail Route 3D Map



1. Parking alongside Llyn Ogwen, this trail route starts by skirting around the North Face of Tryfan, heading for the popular climbing location Tryfan Fach.


2. The path continues straight up Cwm Tryfan valley, essentially a big boulder field with streams and lots of heather. It’s a lovely wander and a gentler way to ascend than other routes up Tryfan.


3. On reaching Bwlch Tryfan, there’s a dry stone wall that links Bristly Ridge and Tryfan. We follow a short section of the wall to the right and then begin scrambling over the boulders to the top. The final plateau before the summit has incredible drops and views.


4. From the summit we usually take the quick (but steep) West Face Descent, although the Llyn Bochlwyd route is great in hot weather for a relax by the lake.
