The current anticyclone or ridge of high pressure over the Uk, is going nowhere for the next few days, so if i was in the area thinking of a walk, i would attempt Glyder Fawr via the Gribyn Ridge.
Even though it;s early Autumn, the temperature today outside Porthmadog was 18C, and the Snowdon summit cafe looked simply majestic from the Cobb.
If your stuck for a walk tomorrow, how about tackling Glyder Fawr via the Gribyn Ridge above Llyn Blochwydd.
It's a very easy scramble onto the main Glyder plateau, and one can easily descend by the same route.
One should grasp every opportunity when very high pressure is smack bang over the country, and the Glyders in sunny weather, are amongst the best mountains ( apart from the Carneddau) in Snowdonia.
