Mar 2025 - Ascent from Llyn Ogwen. Fabulous walk/climb. Milder than expected due to the absence of any wind whatsoever. Met a guy, Paul, from Stoke and walked the majority of the way with him. Crampons need for the last 150m up to the summit. Superb views and the sun came out in the afternoon. Descended via the Heather Terrace, a great but slow route.
