It is a steep climb to get here from either the north or south, but easier than Rhinog Fawr from the west. Great views, and the cliffs of the west side side are a playground for rockclimbers.

The Rhinogs are rightly recognised as being the roughest hills in Wales, so any ascent should bear that in mind. The easiest and clearest route is from the East, starting from the small car park at the end of the lane off the A470. This route is easy to follow and relatively easy to walk. The routes from the west include very difficult walking and few paths.

A circular walk through the historical Nannau estate and along the shore of Llyn Cynwch The Precipice has a fantastic array of qualities. From habitats such as woodlands and meadows to captivating views of Snowdonia’s mountain ranges. The path will take 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 shores of Llyn Cynwch—a working reservoir that provides nearby Dolgellau with water.

Llyn Cynwch acts as both a 'prequel' and 'sequel' to the Precipice Walk, one of the most famous and popular walks in the area with breathtaking views. You'll get a glimpse of the lake if you take the route counterclockwise and you'll see it in all its glory if you finish the walk with a nice, steady stroll along the banks. Together with the Precipice Walk it is part of the historic Nannau estate and is a working water basin that has supplied drinking water for Dolgellau since 1968. Because it is a water basin, swimming is not allowed. (DOLGELLAU.uk)

Cadair Idris, on the southern edge of Eryri (Snowdonia), is a majestic mountain and a grand adventure for runners. Standing at 2,930 feet (893 m), it's a challenging ascent, but the paths are good and the views - if you're lucky enough to visit on a clear day - are spectacular. Most people will use the Pony Path from the north or the Minffordd Path from the south, both of which offer an engaging way to climb or descend the mountain. The two llyns (one on each side of the mountain) can be added into a run to create a figure of eight from either side, with amazing scenery and lots of ascent and descent. Underfoot, the trails are well-maintained but the summit is quite rocky. There's a roomy stone shelter near the summit, handy for taking a break out of the wind before tackling the descent.

A working reservoir that provides water for nearby Dolgellau. Local legend has it that fairies live here so keep an eye out!

A beautiful spot for a wild swim on the way up Cadair Idris. The rocks underfoot can be quite sharp and it gets VERY deep - the lake itself is something like 50m deep!
