First, a somewhat adventurous ride on the single track to the parking lot, which costs £5. The easy loop around the lake is very beautiful and relaxing – the sheep roam freely, but they keep their distance. Dogs must be on a leash, of course, but that's not a problem. Enjoy it – and if you're up for more, go for a longer loop. There are a few tables and benches above the parking lot for your picnic. You won't find any litter baskets, so you'll have to take them with you – which is perfectly fine, as it's a nature reserve. Highly recommended.

Cadair Idris, on the southern edge of Eryri (Snowdonia), is a majestic mountain and a grand adventure for runners. Standing at 2,930 feet (893 m), it's a challenging ascent, but the paths are good and the views - if you're lucky enough to visit on a clear day - are spectacular. Most people will use the Pony Path from the north or the Minffordd Path from the south, both of which offer an engaging way to climb or descend the mountain. The two llyns (one on each side of the mountain) can be added into a run to create a figure of eight from either side, with amazing scenery and lots of ascent and descent. Underfoot, the trails are well-maintained but the summit is quite rocky. There's a roomy stone shelter near the summit, handy for taking a break out of the wind before tackling the descent.

A beautiful spot for a wild swim on the way up Cadair Idris. The rocks underfoot can be quite sharp and it gets VERY deep - the lake itself is something like 50m deep!

The Cadair Idris is certainly not the highest mountain in Wales. Still, it was definitely worth climbing this mountain. Mountains in Wales have an ancient look to them in my opinion. The weather can be very unpredictable and changeable, which means something adventurous and mysterious. This walk is started via the pony path, between trees along a lovely stream. It opens out onto a mountainside of grass and heather while also overlooking rugged slopes. It is rocky at the top of the mountain. Also the first descent via the Fox path. You descend between mountain lakes and see the sea in the distance. Then you come to a beautiful moorland where a stream meanders through and runs between grazing sheep. You end up in a fresh green area. Tip: A good GPS is recommended. When the fog sets in, you as a tourist really do not succeed in orienting yourself on your location. And the weather can be fierce.

These twin lakes are particularly beautiful and lie just north of Cadair Idris. Both are owned by the National Trust and are free to visit. With mountains rising around them and views down to Barmouth and its estuary, don't leave your camera at home, because this is a fantastically photogenic spot.
