Nice ascent from Crosskeys, but watch out for very overgrown pathways on the Machen side. Great views from the top!

Hengoed Viaduct is an old railway viaduct that’s now a walkway and extension of NCN Route 47. It offers a nice view over the valley. The "Wheel o Drams" sculpture (locally known as "The Stargate") by Andy Hazell, is formed from a circle of coalmining dram trucks.

What are the views like from Mynydd Machen?

The summit of Mynydd Machen offers some of the most rewarding panoramic views in the region. On a clear day, you can see across the Severn Estuary towards England, as well as sweeping vistas over Newport and Cardiff. The climb is challenging but the expansive scenery from the top makes it a worthwhile objective for experienced hikers.

Are there any long-distance hiking options starting from Maesycwmmer?

Yes, the area is a great starting point for more challenging, long-distance hikes. For a full day of hiking that takes in some of the region's best features, the Hengoed Viaduct loop from Hengoed is an excellent choice. This difficult 11.7-mile (18.8 km) route involves significant elevation gain and rewards you with varied terrain and impressive views.

What kind of terrain should I expect on the trails?

The terrain around Maesycwmmer is quite varied. You'll find gentle, flat paths along the Rhymney River and across the Hengoed Viaduct, which are suitable for most fitness levels. Many routes also venture into woodlands with well-defined but sometimes muddy tracks. For more of a challenge, the trails leading up to hills like Mynydd Machen involve steeper, more rugged ascents on uneven ground.

Are there any walks that feature the area's industrial heritage?

Absolutely. The landscape is rich with industrial history, and many trails incorporate these features. The Hengoed Viaduct, a former railway bridge, is a centerpiece of many walks.

Another option is Craig Yr Hesg Nature Reserve, which provides a more rugged experience with paths winding through a former quarry site.

Where can I find good viewpoints without a strenuous climb?

Many of the shorter circular routes that include the viaduct provide these scenic rewards with minimal effort.
