There's a path on the map but in reality it's not there, or at least so unused it's invisible. This is an infuriating bog/marsh of deep furrows, large boulders and waist high grass. It is very challenging and stretches for miles in all directions.

Tough climb up from Llyn Cwm Bychan. it plateaus near the top but is very boggy and the path is almost non existent and clearly not used much. Coming down the east side is essentially a scramble over terraces of rock formations and then slogging it through thick bog and high grass in between, with no path at all. It's a very tough walk.

Steady, rocky climb through a majestic valley. A lot of the path follows the stream so can be wet and boggy. This is fairly challenging and better for more experienced walkers.

If you are walking from the west, this will be a blessed relief as the paths become clearer for a while.

A wild and beautiful place, high between Rhinog Fach and Y Llethr

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.

Llyn Hywel is a wild and beautiful place cradled high between Rhinog fach and Y Llethr. It is famous for the huge slab that dives straight into the water on it's eastern side.

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.

Yes, there are over 200 marked hiking routes in the Llanfair area. They range from easy coastal walks to difficult mountain treks in the Rhinogydd range, offering plenty of options for all skill levels.
The trails are highly rated by the komoot community. Hikers often praise the stunning coastal views, the wild and remote feeling of the mountains, and the mix of historical sites like Harlech Castle with natural landscapes.
Absolutely. A great option is the Harlech Castle – Harlech Beach loop from Llanfair. It's a relatively short walk that combines beautiful beach scenery with impressive views of the historic castle, making it engaging for all ages.
Many trails in the area are suitable for dogs, especially the coastal paths and beach walks. However, when hiking in the Rhinogydd mountains or near farmland, it's crucial to keep your dog on a lead, as this is a sensitive environment with livestock and ground-nesting birds.
Yes, for a rewarding hike that includes a waterfall, consider The Roman Steps – Pistyll Gwyn Waterfall loop from Harlech. This moderate route follows an ancient path through the rugged landscape to the beautiful Pistyll Gwyn Waterfall.
For experienced hikers seeking a challenge, the Rhinog Fach to Y Lethr route is an excellent choice. This is a long and difficult trek through the heart of the Rhinogydd mountains in Eryri National Park, known for its rough terrain and significant elevation gain.
Yes, the Wales Coast Path runs right through this area. You can easily join a section of it for a fantastic coastal hike. A popular choice is the Harlech Beach – Harlech Castle loop from Harlech, which incorporates parts of the coastline and offers wonderful sea views.
Sturdy hiking boots with good grip and ankle support are essential. The terrain can be very mixed, from sandy paths along the coast to uneven, rocky, and often boggy ground in the Rhinogydd mountains. Waterproof boots are highly recommended year-round.
These hikes are in the southern part of Eryri National Park (Snowdonia). They explore the Rhinogydd, a range of mountains known for being wild, rugged, and less crowded than the northern peaks. The area lies between the coast around Harlech and the A470 road.
Yes, many of the best routes are circular. For a challenging loop in the mountains, the Rhinog Fawr Summit Cairn – Llyn Du loop is a fantastic option that takes you to a summit and a mountain lake before returning to your starting point.
For a mountain hike here, you should be well-prepared. In addition to sturdy boots, pack waterproof outerwear, extra layers of clothing, a map and compass (or a fully charged phone with offline maps), plenty of water, and high-energy snacks. The weather can change very quickly in the mountains.
