Other walks in the area
Snowdon from Llanberis
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.
Moel Eilio & Moel Cynghorion from Llanberis
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.
A Glyderau trio: Glyder Fach, Glyder Fawr and Tryfan
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.
A circuit of Llyn Idwal from Ogwen Cottage
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.
Snowdon via the South Ridge and Rhyd-ddu Path
This ascent of Snowdon is realatively quiet yet allows the walker to appreciate the grandeur of the highest mountain in Wales. The outward route uses Snowdon's south ridge with the return route following the Rhyd-Ddu path.
Rhyd-Ddu & Llyn y Gader

Pretty walk across the South-West slopes of Snowdon, then a riverside section and finally woodland and a lake
Snowdon and Y Lliwedd from Pen-y-pass
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.
