The Northern Carneddau is one of Britain's forgotten lands when it comes to hillwalking. The bleak landscape, much of it above 3000ft, often suffers from being the tired final leg of a Welsh 3000ers round, but if it were anywhere else in England or Wales this would be as popular as The Glyders or High Street.

Stunning views over the Menai Strait to Anglesey greet you at Bera Bach, while Garnedd Uchaf is the gateway to the much more popular Carnedd Llewellyn and southern Carneddau.


Section 1: Bont Newydd to Bera Mawr

Distance: 2.4 miles (3.9km)

Height Gain: 2179 ft (664m)

Average Time: 2 hours 40 mins


Starting from the Forestry Commission car park at Bont Newydd follow the wide track upstream alongside the Afon Rhaedr Fawr towards the famous, and very popular, Aber Falls.

Beyond the visitor centre at Nant Rhaedr the path climbs steadily through open moors to the base of the falls. A stile on the left leads up beneath scree slopes before reaching the edge of the plantation and a right turn to traverse the scree.

Now the path crosses a ravine before entering the upper Agon Goch valley and a steep haul up to the north ridge of Bera Mawr. Follow the North Ridge first on grass then boulders to near the summit of Bera Mawr, then scramble the final few feet to the top.

From here you can see across the Menai Straits to Anglesey, and on a good day the Mountains of Mourne in Northern Ireland are just visible on the horizon.


Section 2: Bera Mawr to Foel Fras

Distance: 3.6 miles (5.7km)

Height Gain: 1130 ft (344m)

Average Time: 2 hour 20 mins


From the summit descend through the rocks on the east side to a well trodden path that climbs to the summit of Yr Aryg.

A brief levelling is followed by the 150-metre haul up the flank of Garnedd Uchaf, crossing the 3000ft contour just before the summit. The path descends from the rocky ridge of Garnedd Uchaf to a small bwlch before rising steeply again to the next of the 300fters, Foel Grach. From here the southern views are dominated by Carnedd Llewellyn and Yr Elen off to the right.

From Foel Grach reverse the route back to the bwlch, but this time head North East at the junction. As you approach Foel Fras the ground becomes somewhat boggy and a wall appears directing you northwards to first the stone shelter then the OS trig point which marks the mountain's summit, another of the Welsh 3000ers.


Section 3: Foel Fras to Pont Newydd

Distance: 5.6 miles (9km)

Height Gain:156 ft (47m)

Average Time: 2 hour 20 mins


From Foel Fras the route lies predominantly downhill. The wall turns into a fence as you drop down from the summit to a bwlch, then a short and relatively gentle reascent to Drum.

Beyond the stone shelter the path drops again, heading north and following the fence on its left. Now descend to another bwlch and drop down to the left to join a large track built to service the Llyn Anafon reservoir.

Continue along this track to join another, equally broad and obvious, track heading left. This track continues downhill and eventually turns into a minor road that takes you back to Bont Newydd and the starting point.


Note: Average time ratings are calculated for a notional average walker and take height gain into account. You may be faster or slower than the notional average, but they provide a starting point.
