Llyn y Fan Fawr is a go to blues buster, soul filler and general brilliant walk all year. But in winter if you pick a day when the valleys are full of mist, the water glows, when the peaks above are crusty with icing sugar, it packs an extra special punch.
Highlights: Great views to Corn Du & Pen y Fan. Quieter than Llyn y Fan Fach.
Time:You can walk straight up in about 45 minutes, but there are also lots of loop options to Fan Brycheiniog and also right on round for a all dayish yomp including llyn y Fan Fach.
