Gwydir Forest Park

Gwydir Forest Park lies in the heart of the Snowdonia National Park.

Since Victorian times, generations of visitors have walked the woodland paths and fished the clear waters of the rivers here.

Today, waymarked walking trails allow visitors to explore this landscape of lakes, forests and mountains and to learn about its mining history.

There is also a mountain bike trail (which is graded red as it is only suitable for proficient riders), a forest garden and a waymarked walk to the famous Swallow Falls.

History of Gwydir Forest

Between 1850 and 1919, lead and zinc mining dominated the area. The legacy of old engine-houses, waste tips and reservoirs are characteristic features of the forest landscape today.

Nearly all of the lakes in the forest were created to serve the mines.

Several of the most important mines have been partially restored and made safe for visitors.

Nowadays, as you explore the extensive, rolling upland of wooded knolls, lakes and pastures, you will find it difficult to imagine that this was once a derelict industrial landscape.

Visiting Gwydir Forest Park

Gwydir Forest Park covers an area of over 72 square kilometres (28 square miles) and it encircles the village of Betws-y-Coed.

Waymarked walks start from the following parts of Gwydir Forest Park:


Sawbench is the starting point for the Gwydir Mawr Trail, a red graded mountain bike trail which means it is only suitable for proficient riders with good off-roading skills.

For walkers, there is a short walk with great viewpoints overlooking the market town of Llanwrst.

Lady Mary’s Walk

1¼ miles, 2.1 kilometres

This short walking trail is named after Lady Mary from the Wynne family who established the Gwydir estate – the summer house and chapel are nearby. There are benches along the route to enjoy the views over Llanwrst and the Conwy Valley towards the sea.  

Mountain biking trails

The 24.8 km Gwydir Mawr Trail is a long established mountain bike trail and, for those who want a shorter ride, the Gwydir Bach Trail follows 9.1 km of the main trail.

The mountain biking trails are waymarked and start from Sawbench car park.

See our mountain biking page for a list of all our mountain bike trails and information about grading to make sure you pick a trail that is right for you.

Please also read the relevant onsite information before setting off on your ride. 

Gwydir Mawr Trail

24.8 kilometres, grade red (difficult)

Gwydir Mawr has big climbs, big descents and brilliant singletrack. Most of the climbs are on forest roads and tracks giving time to take in the mountain views. The descents are on singletrack which varies from very tight, technical and rocky to open and flowing.

Gwydir Bach Trail

9.1 kilometres, grade red (difficult)

Gwydir Bach is the little sister to Gwydir Mawr but its two big climbs lead to the best descents of the whole trail. The singletrack varies from very traditional tight, technical and rocky to open and flowing, with a few modern features thrown in.
