Gwydir Reservoir Safety Work - increased traffic on Forest Roads

 

The above project will be using a route through this area of the forest to take material to site. Due to this, there will be an increased volume of lorries using some of the road network.

Welcome

Llyn Sarnau means “lake of the old tracks” in Welsh and it is a lovely place for a picnic at one of the tables around the car park.

The lake is fairly shallow and so it often dries out in summer.

Even though it may not be much to look at during warmer months, it's a valuable home for wetland loving wildlife.

The Forest Lakes Walk goes to two other lakes, which are hidden from view from the car park.

Walking trail

The walking trail is waymarked and starts from the car park.

Forest Lakes Walk

Distance: 2¾ miles/4.3 kilometres

Grade: Moderate

Highlights: Discover beautiful mountain and valley views, scenic lakes and old disused lead mines. Head out from the car park and take your time to appreciate the view from the benches. Reach a path that goes around then down the middle of a small lake. Meander through the old High Hafna mine, once a hive of industry, then continue along an undulating path through the woods, taking in a viewpoint on top of a cliff edge.

Trail description: Most of this trail is on forest roads connected by rough narrow paths less than 50cm wide in some places, on unmade and uneven surfaces, where you can expect mud, rocks and tree roots. There are three benches on the trail, and a wheelchair accessible picnic table in the car park.

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.

Exploring 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:

The Gwydir Mawr Trail, a red graded mountain bike trail with big climbs and singletrack only descents, starts from Sawbench.
