Lyn yr Oerfel

High up in the Snowdonian hills, Lyn yr Oerfel sits cold and grey under most Welsh skies - which is rather fitting given its name translates to 'Lake of the Cold Wind'. Getting there demands a proper walk from Blaenau Ffestiniog, and it's not the sort of stroll you manage in trainers. The lake itself is stark alpine stuff, surrounded by barren moorland that feels genuinely remote even though civilisation isn't far below.

Walkers will get the most from this one. It's the sort of place you visit as part of a bigger Snowdonia circuit rather than a standalone trip, and the journey matters more than the destination. The water reflects whatever light breaks through the clouds, which can range from brilliant silver to moody gunmetal. On a clear day - rare enough up here - the views back towards Blaenau Ffestiniog and the surrounding peaks are genuinely excellent.

Allow a good three to four hours for the round trip depending on fitness and how much poking about you do. There's no café, no facilities, nothing really - bring what you need. It's free to visit, naturally, since it's open hill country.

If you're based at Llechwedd Glamping at Plas Weunydd nearby, this makes a worthwhile afternoon or morning excursion, particularly if you're after something less travelled than the main Snowdonia honeypots. Fair warning though - the walk is exposed and weather changes fast. Not brilliant for small children or the reluctant.
