There are diversions signposted on site for these trails:


  • Skyline
  • Blade
  • White’s Level

Blade Trail – due to harvesting operations the trail sections ‘L1’ and ‘Twister’ are closed with diversions in place until the work is completed.


The optional ‘Tyn-y-pan’ section of White’s Level mountain bike trail has been re-graded as Black (severe).


Afan Forest Park was created in the 1970s and has grown into one of Britain’s iconic mountain bike destinations.

Situated in a former coal mining valley a few miles from the M4, the forest park offers mountain bike trails for beginners to expert riders.

Three of our red-graded mountain bike trails start from the car park at Glyncorrwg Mountain Bike Centre.

You can also join the green-graded Rheilffordd Low Level Cycleway from the car park here.

Most of our mountain bike trails start from Afan Forest Park Visitor Centre.

Mountain bike trails

All our mountain bike trails are waymarked from start to finish and have been graded for difficulty.

At the start of the trail there is an information panel – please read this before setting off.

Rheilffordd Low Level Cycleway

This gentle trail follows the wide, flat route of an old railway track that once carried passengers and coal the length of the valley.

Over 14 miles of disused railway and forest road link the communities of Pontrhydyfen with Blaengwynfi and Glyncorrwg and it’s a great way to explore the Afan Valley.

White’s Level Trail

  • Grade: Red (difficult)
  • Distance: 15.4 kilometres (with optional additional 2.3 kilometre black-graded loop)
  • Climb: 405 metres
  • Time: 1½-3 hours

This is the most technical of all the trails in Afan Forest Park and is 90% purpose-built singletrack.

A 6 kilometre sheep-track climb gives fantastic views of the Afan Valley.

Extreme exposure on tight singletrack means ultimate thrills and long, demanding descents with rocky steps to negotiate, all leading to one outrageous trail.

There is an optional additional 2.3 kilometre black-graded loop.

For a longer ride, combine with Y Wal Trail via one of the W2 links.

Blade Trail

  • Grade: Red (difficult)
  • Distance: 23.6 kilometres
  • Climb: 570 metres
  • Time: 2½-3½ hours

The Blade Trail has lots of singletrack, offering a great trail for more experienced riders.

This trail takes you to higher and more remote sections of the forest with amazing views over the Brecon Beacons National Park.

It twists and winds through the distant forest with some tough technical climbs and descents before dropping back to Glyncorrwg.

You can also add-in a loop of the Skyline trail but make sure you are properly equipped as this extra loop takes you to a very remote area with changeable weather conditions.

The 'Ghost Train' section of this trail is permanently closed, awaiting removal. For health and safety reasons, please do not ride this section.

Skyline Trail

  • Grade: Red (difficult)
  • Distance: 46.5 kilometres
  • Climb: 995 metres
  • Time: 4-7 hours

After being closed for several years due to the development of a nearby wind farm, the Skyline Trail has been redesigned and it reopened in October 2021.

The trail shares the same sheep-track ascent as White’s Level, and continues on long, forest road climbs with sweet, flowing technical singletrack descents.

You will be treated to stunning, skyline views of the Brecon Beacons, the Preselis, the Black Mountains and the South Wales coast.

This route will test your stamina and your nerve, with technical singletrack such as sections ‘On The Edge’ and ‘Excalibur’.

There are also 2 short-cut loops built into the trail.
