Discover the Majestic Trails of Eryri

Welcome to one of the most breathtaking outdoor playgrounds in the United Kingdom. Formally known as Eryri, Eryri National Park covers over 2,000 square kilometres of rugged peaks, deep valleys, and coastlines. Whether you are looking to conquer legendary summits or stroll through historic landscapes, this stunning region has something for every adventurer.

Before you pack your bags, it is worth noting that the National Park Authority maintains 1,497 miles of approved paths. These diverse trails provide the ultimate opportunity to fully immerse yourself in the unique Welsh wilderness. Beyond the gorgeous views, spending time walking here does wonders for your physical health and your mental well-being.

To keep you safe and happy on your journey, always research your chosen route thoroughly and check the local weather. Let's dive into the absolute best hikes this national park has to offer.

1. Snowdon via the Pyg Track (and Llanberis Descent)

While there is so much more to this park than its highest peak, you simply cannot ignore Yr Wyddfa (Snowdon). Standing tall at 1,085 meters, it is the crown jewel of North Wales. This classic circular route begins at Pen y Pass and ends with a gentle stroll back into Llanberis.

Parking at Pen y Pass can be incredibly difficult and expensive, so taking the local bus from Llanberis is highly recommended. The Pyg Track climbs steadily above shimmering lakes, wrapping around a spectacular mountain horseshoe. Once you reach the summit trig point and soak in the views, you can descend along the straightforward Llanberis Path which runs parallel to the mountain railway.

2. The Glyderau Circular Hike

If you love dramatic, rocky landscapes, the Glyderau range is your dream destination. The name itself translates from Welsh to mean "pile of rocks," which perfectly describes this rugged terrain. This particular loop avoids technical scrambling but still delivers incredibly dramatic scenery.

Starting from Gwern Gof Uchaf in the Ogwen Valley, you will ascend along the impressive Heather Terrace beneath Tryfan. As the trail levels out, you will find yourself on the summit of Glyder Fach. Here, you can gaze at the famous Castle of the Wind, a jagged crown of stone that looks like something out of a fantasy novel.

3. Carneddau Ridge Peak Bagging

For those who want to escape the crowds and bag multiple summits in a single day, the Carneddau range is unmatched. This long, high-altitude ridge walk runs from north to south. Because it is a linear journey, you will need to plan transportation at both ends before you start.

Starting near Rowen, you will follow an ancient Roman road up to the ridge. From there, you will stay high to cross peaks like Foel-fras, Carnedd Llywelyn, and Pen yr Ole Wen. It is a long, committing day out, so make sure to choose a window of clear weather to enjoy the sweeping vistas.

4. Cadair Idris via the Minffordd Path

Located in the southern part of the park, Cadair Idris is a mountain steeped in local folklore. Legend says that a giant named Idris lived here, and that spending a night on the summit will leave you either mad or a poet. The lake nestled in its center, Llyn Cau, is also rumored to be completely bottomless.

Climbing via the Minffordd Path is widely considered the finest way to experience this mountain. The trail starts with a steep climb up steps through the woods beside the Nant Cadair river. It then opens up to a stunning horseshoe ridge, offering panoramic views that stretch all the way to the sea.

5. The Nantlle Ridge

The Nantlle Ridge is famous for its distinctive, wedge-shaped silhouette that snakes toward the coast. While the traditional route features a Grade 1 scramble, hikers can easily bypass the technical sections by staying on the path to the left of the crest. This allows you to enjoy a thrilling ridge walk with minimal stress.

Starting from the Rhyd Ddu car park, you will head west over grassy slopes to the summit of Y Garn. The undulating ridge line then guides you past a historic slate obelisk at Mynydd Tal-y-mignedd. Your descent path will eventually lead you down past the peaceful waters of the Llyn Cwm Dulyn reservoir.

6. The Snowdonia Slate Trail

If you want to experience the rich cultural heritage of North Wales, this trail is a must-visit. The slate landscapes of this region have been officially designated as a UNESCO World Heritage site. Rather than climbing steep peaks, this circular route focuses on history, local culture, and valley scenery.

Starting and finishing in the city of Bangor, the trail takes you past historic quarries, ruined buildings, and old mining works. It is the perfect option for those who want to explore the quieter, lesser-known corners of the national park at a relaxed pace.
