Afan Forest Park - Glyncorrwg Mountain Bike Centre, near Port Talbot
Starting point for three of our red-graded mountain...
The Raven mountain bike trail is closed due to safety reasons.
Situated a couple of miles from the village of Brechfa, the Byrgwm car park is the starting point for mountain bike trails through Brechfa Forest.
Inexperienced off-road cyclists can get an introduction to mountain biking on the Derwen Trail which flows through the oak woodland.
The black-graded Raven Trail was designed by two well-known mountain bikers and it will test the skills of experienced riders.
The walking trail passes a derelict smallholding, one of several ruins throughout Brechfa Forest.
The woodland boasts some huge Douglas Fir trees and plant enthusiasts should look out for hard fern, broad buckler fern and bilberry.
There are portaloos in the car park.
The walking trail is waymarked from start to finish.
Look out for the information panel at the start of the trail.

This walk takes in views of the Cothi Valley, airy woodlands with huge Douglas fir trees, darker moss strewn Norway spruce areas, and a derelict smallholding.
Don’t be put off by the forest road ahead – soon views of the Cothi valley open up to your right with its landscape of farms and woodlands.
After just under a mile you will turn left leaving the road to go along attractive woodland paths.
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.
Typically, green trails are all on forest roads or canal towpaths – but not in Brechfa Forest! We aimed to create a trail that engages the rider and heightens your senses giving a true taste of off-road riding.
Named after the oak woodland it effortlessly flows through, the Derwen trail gives the inexperienced off-road rider a unique introduction to the world of mountain biking.
Clinging low to the valley sides, the trail eases you in with steady climbs and fun descents. Weaving through the forest you will encounter some lovely scenery and flowing terrain.
One ride will have you hooked and, perhaps, thinking of trying out the blue-graded extension.
This extension to the green-graded route climbs a steeper bank before taking in a longer, faster descent that will have you pumping and whooping all the way to the valley bottom.
This route is also a stepping-stone to the steeper and more technical red-graded Gorlech Trail from our car park at Abergorlech.
Suitable only for proficient bikers, the trail effortlessly mixes up the more traditional narrow woodland singletracks with Brechfa’s signature brash descents: fast, undulating trail that sweeps between trees and flows sinuously into berms and over jumps.
This trail takes you out into the more interesting corners of the forest and creates a ride that involves the forest’s unique environment, from spooky mossy overhangs to the magnificent Douglas fir Northshore Bridge.
Designed by Rowan Sorrell and Brian Rumble, this trail will test your full artillery of trail skills.
Brechfa Forest is the modern name for part of the ancient Glyn Cothi Forest.
Glyn Cothi Forest was managed for centuries by local people in order to provide building materials, products and grazing.
In 1283, following the final defeat of Wales by Edward I, Glyn Cothi became a Royal Forest administered under Forest Law for several centuries.
Since those days a very different forest has developed. In the 1900s Brechfa Forest was replanted with conifers by the Forestry Commission to boost Britain’s timber reserve after the heavy use of timber in the First World War.
Today Brechfa Forest covers some 6500 hectares and is looked after by Natural Resources Wales for the benefit of people, wildlife and timber production.
Horse riders are welcome on forest roads.
Brechfa Forest forms part of the National Forest for Wales.
The National Forest will:
In time it will form a connected ecological network running throughout Wales, bringing social, economic and environmental benefits.
