Crossing the moorland from Rhigos towards Aberdare is a network of gravel forest roads.

Great in the sun, but not so good with the wind in your face, it's an ideal way to cover round fast and stay off the tarmac.

At the far point of the Skyline trail is a viewpoint where you can look out into the Brecon Beacons, and hopefully (on a clear day) catch a glimpse of the National Park's highest peak – Pen y Fan.

Tucked away in a dreamy, isolated location in the upper Swansea Valley, Craig-y-nos Country Park is a gorgouous 40-acre park that was once owned by Adelina Patti. Now it is a Victorian garden set in woodlands, surrounded by meadows and ponds, dissected by the River Tawe. It is in a gorgeous location, and there is a great cafe there to boot.
