Twyn Crugyrafan [Graig Fawr]

Looming over the Afan Valley, this Marilyn is less a jagged peak and more a hard-working piece of South Wales moorland. It offers a bracing mix of Bronze Age history and modern renewable energy, served with a side of potentially spirit-crushing bog.

• •The summit is crowned by an ancient Bronze Age burial mound, suggesting that even 4,000 years ago, people were willing to endure a steep climb for a decent burial plot.
• •As the highest point in Neath Port Talbot, it holds 'County Top' status, a title it defends with stoic, rain-soaked dignity against its lower neighbors.
• •The landscape is a patchwork of industrial history, with nearby coal seams having once fueled the world while the summit remained a quiet observer of the Rhondda valley's transformation.
• •Modernity has arrived in the form of towering wind turbines; standing beneath them, the rhythmic 'whoosh' provides a hypnotic, if slightly unsettling, soundtrack to your lunch break.
• •Attempting to locate the true summit among the various hummocks and ruins is a game of 'Guess the Pile of Rocks,' usually won by the sheep who are much better at navigating this terrain than you are.
