October 3, 2025, Rhaeadr Ddu (Black Falls) Waterfalls

A set of double falls, upper and lower. Both are quite tricky to photograph, the upper falls being the more precarious as you have to look over an edge to see the full drop. The lower falls are easier as you can get a low Point of View and hence get the flow of the water past you. These falls are only a few hundred yards up a well marked and obvious path, large car park on the main road at the bottom of the roadway.

September 27, 2025, Rhinog Fach Summit

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.

First, a somewhat adventurous ride on the single track to the parking lot, which costs £5. The easy loop around the lake is very beautiful and relaxing – the sheep roam freely, but they keep their distance. Dogs must be on a leash, of course, but that's not a problem. Enjoy it – and if you're up for more, go for a longer loop. There are a few tables and benches above the parking lot for your picnic. You won't find any litter baskets, so you'll have to take them with you – which is perfectly fine, as it's a nature reserve. Highly recommended.

I started the opposite way of the route, going to the summit of Y Garn the shortest way. It was better. Starting the long way around is too tidings even going down. Be prepared to get lost without Komoot and the path they show (it’s like a compass) because the paths are hardly visible in places. There is an old gold mine worth passing by. The views from Y Garn are well worth all the sweat.

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)
