On the way up, this is the point at which the gradient increases. Careful of the larger stones and loose gravel.

Super cruisy fire road climb to the top of the trails. On the way up you can check out all the trail options jumping off to the sides.

A more picturesque route than heading straight up or down the main fire road to Glyncorwg, and an easier pedal upwards too...the gravel is (mostly) super smooth From North to South (downwards) - Follow the signed "Skyline Trail" (on left, off main fire road) down the double track, and where Skyline turns off into "Grand Canyon" stay on the double track, views into the Valley below are excellent. There are a couple of poorly repaired sections, where larger gravel has been used, so take care when descending at speed. When coming from the South to North (upwards) - Turn off right on the main fire road climb and stay on the double track fire road all the way up. The surface is super smooth and makes for an easier climb than the main gravel fire road up out of Glyncorwg to eventually make the Rhigos mountain road.

The Blackmill Path is a fantastic section of National Cycle Route 4 that runs alongside Ogwr Fach, linking Blackmill to the west to Hendreforgan and Tonyrefail. It also features on the Celtic Trail, a long distance cycleway from Fishguard to Chepstow. The relatively new, smooth tarmac path cuts through glorious countryside and is a much-needed alternative to the busy main road on the other side of the river.
