Hiking
Embark on an easy 3.5-mile (5.7 km) loop that takes about 1 hour and 31 minutes, with a gentle elevation gain of 223 feet (68 metres). This hike offers diverse scenery as you pass through deciduous woodland, conifer plantations, and meadows. Enjoy panoramic views down to the Mawddach Estuary and out to the sea, reaching as far as Barmouth, and admire the serene Llyn Cynwch. You will also see sweeping vistas of Snowdonia's principal mountain ranges, including Yr Wyddfa (Snowdon).
Plan your visit to this popular loop near the historic market town of Dolgellau. The trail is on private land belonging to the Nannau Estate, which grants public access, but be aware the route is typically closed one day a year, often on February 1st. While generally easy, the path can be narrow, rocky, and uneven in places, so wear appropriate footwear like boots. Some sections traverse a narrow ridge with steep drops, which might be a concern if you have a fear of heights, but it is suitable for most fit walkers and families with children aged eight and above.
This route, known as the Precipice Walk, has a rich history, originally created in the 19th century by Henry Robertson, a wealthy industrialist. He designed it to showcase the area's beauty to his guests. It is known as a “contour walk” because the path largely follows the 800-foot contour line, meaning there is not excessive climbing or descending throughout most of the route. The trail also offers a tour of the historic Nannau Estate, which dates back to the twelfth century.

To round off our holiday in Wales, we took this walk that is very well known in this region, the Precipice walk. It is a walk through the historic Nannau estate and along the banks of Llyn Cynwch. The walk is very varied. From habitats such as woodlands and meadows to fascinating views of Snowdonia's mountain ranges. The path takes you through part of the Nannau estate, which dates back to the 12th century and is steeped in fascinating Welsh history. The route ends on the banks of Llyn Cynwch, a working reservoir that supplies water to nearby Dolgellau.
Gorgeous walk where you get all the views without having to go too far uphill. The lakes and hills, with a few little rocky bits, keep it exciting.
Forgot to record the start of the walk ... but excellent views over the valley and River Mawddach estuary towards Barmouth.
