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.

This the deep narrow pass between Rhinog Fach and Rhinog Fawr. This photo shows where the path down from Rhinog Fawr meets the path that cuts through the pass, and also the steep path up Rhinog Fach. Also note how rough it is.

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.

Moel-y-Gest is a great little hill with super good views towards the Snowdonia range and down the length of the Llŷn Peninsula. It has a nice nice rocky top and a very imposing, well kept stone trig pointed summit.

The pass between the breathlessly rugged Rhinogs Fach and Fawr is notorious. Many who have explored this way have been taken aback by a rough hewn landscape of concealed boulders and heather that doesn't give up its secrets lightly. From the bwlch are superb views across to Lake Trawsfynydd and the Arenigs. Both Rhinog Fach and Rhinog Fawr can be ascended from here.

Foel Penolau is one of the rockiest peaks in Snowdonia and it requires some scrambling to get to the summit. When you arrive, though, expect fine views north towards the Snowdon massif, south to Rhinog Fawr, and the impressive Llyn Trawsfynydd reservoir to the northeast.

While the Roman Steps Walk is a captivating hike through the dramatic landscapes of the Rhinog Mountains, it is primarily known as a historic route rather than a natural monument itself. It traverses verdant valleys and rocky outcrops, offering panoramic views of Snowdonia National Park, and is a popular way to experience the rugged natural beauty of the area.
The best time to visit is generally during the spring (April-May) and autumn (September-October) months when the weather is often milder and the landscapes are vibrant with new growth or autumnal colours. Summer (June-August) is also popular, but can be busier. Winter offers a more rugged and solitary experience, though weather conditions can be more challenging.
