Begin your adventure by leaving the train station and traveling approximately .4 mile to the Monmouth & Brecon Canal (NCN Route 49). The main road leaving the station can be a little busy, so show caution when crossing to reach the canal path entrance.
The entirity of the canal path is unpaved and varies in width from six feet to just a single-track, but it is very smooth. The main concern are the many small bridges you must pass under. In some cases you can cycle, but for many it is safer to get off your bike and walk. Regardless, it's always a friendly reminder to give a shout or ring your bell to alert anyone coming from the opposite direction.

You should note that you've entered the canal path just above Pontymoile Boat Basin. (This will be your same point of exit at the end of your ride.) But for now, you can sit back and just enjoy the scenery. You've got an easy, relaxing, and quite lovely 13 mile ride ahead of you to Govilon Wharf.
Six miles from Pontymoile Boat Basin is Gotre Wharf. It's a charming spot to stop and stretch your legs. There is a cafe serving teas & coffees, as well as hot lunches (and toilets). It is a historical location with old lime kilns to explore, as well as many quaint and interesting canal boats to admire.
As you can see in the photo above, the path does get narrow in places. However, for the most part it is wide enough to pass other cyclists and pedestrians with ease (shown below).
Six miles from Goytre Wharf, you'll pass through the charming boat landing at Llanfoist Wharf. It is well worth your time to stop and explore a bit.
This was an important junction for the coal industry for over a hundred years. There are several old relics of when coal was dropped down the mountain from Big Pit to be loaded onto barges. Plus, there's a cool and spooky tunnel that goes under the canal and adjoining guest house on the opposite side!
1.5 miles from Llanfoist Wharf, you'll cross a small foot bridge and begin cycling on the opposite side of the canal. The route becomes quite narrow, but exceptionally charming as you pass several homes perched along the banks of the canal.
At 12.9 miles you'll reach Govilon Wharf which sits on the opposite side of the canal. Here we'll be joining NCN Route 46 where we'll begin the climb upt to Clydach Gorge.
PART TWO

Clydach Gorge |
Distance: 6.2 miles
Elevation: +992 ft / -130 ft
Elevation: +992 ft / -130 ft
As you cycle past the boat docks at Govilon Wharf, you should notice a large bridge crossing the canal. As you approach the bridge, look for a small foot path to your left leading away from the canal and heading up to the bridge. This path is NCN Route 46.
You'll need to disembark your bikes and push them up the short hill to reach the cycle path. Once at the top, turn left to begin the next leg of your adventure where you'll climb nearly 1,000 feet in just over six miles up to — Clydach Gorge!

Note: If you continue along the canal a short distance (.1 mile to the next bridge) you'll reach the village of Govilon where you can find shops, cafes, and public toilets.

Shown below is the brige to look for at Govilon Wharf and NCN Route 46 passing over the canal. You can also see the footpath leading off to the left.
The photo below shows the view looking back down on the M&B Canal.
Once you are on NCN Route 46, you'll cycle approximately two miles up a continuous and steady grade. The path is smoothe, wide, and paved. It's a popular path so be prepared for dogs, walkers and other cyclists.
Note: If you turn right onto NCN Route 46, the cycle path leads back down the valley 1.3 miles to the village of Llanfoist (parallel to the canal path, but lower down the valley...) and from there it is less than .5 mile to the town of Abegavenny.
As the traffic-free section ends, you enter onto a very narrow, but exceptionally quiet lane. As the road veers to the left, the hillside becomes very steep. On your left, it just goes up and up, while on your right, it falls away to the valley far, far below.
This section is quite lovely and the views across the valley spectacular, but show caution as an occasional car may come along this very narrow lane.
After about a mile you will encounter the first very steep hill (+8% grade, see the center zig-zag in the map above). Don't beat yourself up for walking. It's actually good for your legs to change up a bit.
The climb is approximately .2 of a mile and once at the top you'll be amply rewarded. The road is fairly wide and smoothe and offers only a slight incline for the next couple of miles.
Take time to look around. There are elements of the railroad, mining, and the industrial past everywhere. You are about to enter Clydach Gorge.
Often there are groups of gorge walkers, mountain climbers, and folks just exploring this fascinating area. (That's the old Clydach train station in the photo below!)
As you enter the gorge, the pavement gives way to a grassy track which snakes along a steep ledge. You'll cross over viaducts and pass several disused tunnels. Go ahead, get off your bike and walk around. Explore some. By the way, this is a perfect place for your picnic.
Once you pass the two tunnels, the path becomes very narrow again. There is a sheer rock wall on your left which does pose the danger of falling rocks. Chances are you'll see loose rubble along the way.
Be sure to look over the edge of the bridge as you cross... you'll be surprised at your height!
Then go a short distance further and stop. Look through the trees and across the gorge to where you've been. It is quite a view.
The last part of this section is out of Clydach Gorge. It starts fairly easy, but after mild climb up a quiet lane, the route returns to traffic-free and now you have the second steep hill.
There's need to kill yourself here... walking is just fine (+6% grade, see the zig-zag on the left side of the map above). At the top you'll find spectacular views and the junction of NCN Route 492; Part Three of our adventure.
The large mountain in the center foregrond is the Blorenge (technically just a hill, but close enough). In the far distance is the legendary Skirrid.
Note: This climb after leaving Clydach Gorge is actually a temporary detour from the original route. The Heads of the Valleys road has been under construction for a couple of years and the main route has been closed. As they near the end of the road works, we shall see how this changes.
PART THREE

Afon Llwyd Valley |
Distance: 13 miles
Elevation: +437 ft / -1,369 ft
Elevation: +437 ft / -1,369 ft
As you begin the final part of your adventure, you can take pride in knowing that you've traveled nearly 20 miles and climbed almost 1,600 feet. The next 13 miles will fly past.
You've only a very small amount of easy climbing left and soon you'll reach the highest point of the ride above Garn Lakes Nature Reserve. From there, you'll be rewarded with a relaxing glide down through the wooded hillside of the Afon Llwyd Valley — all the way back to Pontypool.

At the top of the hill go through the gate and turn left. The routes are well marked and clear to understand. (Additionally, there is nothing else around but the views, the wind, and some lazy horses.) You are now on NCN Route 492.
Note: If you turn right at the gate, you can continue on NCN Route 46 to the town of Brynmawr. It is just over a mile away and there you can find cafes and toilets.
As you begin cycling again, the path starts with a gradual climb along a traffic-free path, but soon merges onto a narrow lane leading to the top of the ridge at the busy B4248.
Looking back down the valley you can see the three main mountains of the South Wales Valleys; the Sugarloaf (far left), the Skirrid (far right), and the Blorenge (near right).
Show caution as you cross the B4248, but once on the other side, the path changes from tarmac to packed gravel and the valley opens onto a wide plateau flanked by two high ridges.
This is the highest point of your journey. From here back to the Pontypool/New Inn Train Station is nearly all downhill (roughly 10 miles).
This is the highest point of your journey. From here back to the Pontypool/New Inn Train Station is nearly all downhill (roughly 10 miles).
It's important to understand that the weather can change suddenly up here. Firstly, it is generally windy and the clouds can blow in quickly. Secondly, you are completely exposed for the next two miles. The temperature can be 4 -5 degrees colder, as well.
As you approach Garn Lakes Nature Reserve, you will find yourself at the top of small rise overlooking the valley ahead. You will soon enter the Blaenavon World Heritage Site. In the foreground is Big Pit National Coal Museum while the town of Blaenavon itself, lies a little further ahead.
Once you pass the Whistle Inn Cafe, you enter Garn Lakes Nature Reserve. This area was once the site of a coal mining colliery and covered in spoil tips. Following an extensive land reclamation scheme, the site now provides lakes, grasslands, and breeding grounds for a diverse range of wildlife.
Leaving Garn Lakes you will next cross the road leading to Big Pit National Coal Museum. There is much to see along here; however, I highly suggest coming back when you've time to fully appreciate all the sites. See the sidebar below!
Sidebar of Note:
Visit Blaenavon
Located at the gateway to the South Wales Valleys, partly within the Brecon Beacons National Park; the Blaenavon Industrial Landscape is a testament to the human endeavour of miners and ironworkers of the past. Set in 33 square kilometres, the attractions, events, activities and landscape make a perfect destination for a day out. The main attractions such as Big Pit National Coal Museum, Blaenavon Ironworks, the World Heritage Centre and Blaenavon Heritage Railway are all just a few minutes’ drive or walk from each other. Indeed, there are so many brilliant attractions that you need to spend more than a day here to enjoy everything – so plan a weekend if you can!

From Blaenavon you will begin the long fast glide through the lush woods on western side of Afon Llwyd Valley. NCN Route 492 runs practically uninterupted for the next eight miles all the way to Pontypool... and all of it is downhill!
The route itself is a visual delight... just be sure to slow down! It is very easy to let it all race by, because it's all downhill from here. Also of note, there can be dog-walkers and families out for a stroll, show consideration and caution when passing.
Still waiting in Varteg... sculpture on an abandoned platform quietly remembers.
After passing though a narrow cutback, the route emerges from the woods and you will find yourself cycling along a ridge, passing over viaducts with views high across the valley.
You'll know when you're coming into Pontypool for the path changes rather dramatically yet again as the route comes along side the very busy A4043. The town has done an exceptional job of seperating the cycle path from the roads with railings, concrete dividers and numerous bridges - all circumnavigating the many roundabouts. It's rather inpressive.
After passing over several bridges and road crossings, the route re-enters the woods. Then approximately 1/2 mile further the Monmouthshire & Brecon Canal appears to your lower left. Just after you cross over the canal you will see two NCN Route signs. Turn right off NCN Route 492 and then immediately right again onto NCN Route 49 following the canal.
This last section of the route follows the canal back to Pontymoile Boat Basin. From there you can exit the path and return to the Pontypool/New Inn Train Station where you began your ride. Congratulations! You've done it.
Looking back at the assortment of bridges and underpasses where NCN Route 492 crosses over the Monmouthshire & Brecon Canal (NCN Route 49).
