Wales and Ireland: Essential Day-Hikes

Regional overview

This region combines maritime mountains, high moorland, corrie lakes, rocky ridges and Atlantic-facing summits. Eryri/Snowdonia provides the most alpine-feeling Welsh walking, centred on Yr Wyddfa/Snowdon and its ridges. The Cambrian Mountains are quieter, broader and more remote, with Pumlumon forming a high, boggy watershed. In Ireland, Wicklow offers accessible upland walking close to Dublin, Kerry has the highest mountains on the island, and Connemara combines quartzite hills, bog, coast and lake views.

The normal hillwalking season is late spring to autumn, but these routes remain weather-sensitive. Mist, strong wind, wet rock, boggy ground and short daylight can make otherwise non-technical walks serious.

Access varies sharply. Yr Wyddfa has a dedicated Sherpa’r Wyddfa bus network to Pen y Pass; Glendalough has bus access from Dublin and Wicklow; Pumlumon, Carrauntoohil and some Connemara trailheads remain more car-dependent or require careful public-transport planning.

Selection rationale

The five hikes were selected to give one representative essential route from each named area: an iconic national summit in Eryri, the high watershed of the Cambrian Mountains, Wicklow’s classic lake-and-cliff circuit, Ireland’s highest mountain in Kerry, and Connemara’s best-known national-park summit loop.

Summary table

1. Yr Wyddfa/Snowdon via Pyg Track and Miners’ Track

Itinerary

The route starts at Pen y Pass and climbs the Pyg Track towards Bwlch y Moch, with views towards Llyn Llydaw, Crib Goch and the upper cwms of Yr Wyddfa. The path traverses above the lakes before joining the upper mountain path towards the summit ridge. The descent commonly follows the Miners’ Track, passing Glaslyn and Llyn Llydaw before returning to Pen y Pass.

Why it is essential

Yr Wyddfa is the highest mountain in Wales, and the Pyg/Miners combination is one of the most recognised non-technical summit days in Eryri. It combines a major national summit, glacial lakes, views into the Snowdon Horseshoe and a practical return to the same trailhead.

Equipment

• Sturdy boots
• Waterproof and windproof layers
• Warm layer
• Food and water
• Map/GPS
• Navigation backup
• Hat and gloves outside warm settled weather
• Headtorch for late finishes
• Microspikes or winter equipment may be needed when snow or ice is present

Hazards and notes

• Pen y Pass parking is limited and should be planned in advance.
• Sherpa’r Wyddfa bus is the preferred access option in busy periods.
• The upper mountain is exposed to rapid weather changes, low cloud and high wind.
• This route does not include Crib Goch, which is a separate exposed scramble.

2. Pumlumon Fawr from Eisteddfa Gurig

Itinerary

The walk begins near Eisteddfa Gurig and climbs open Cambrian ground towards Pumlumon Fach and Pumlumon Fawr. The route reaches the broad summit area of Pumlumon Fawr, the highest point in the Cambrian Mountains, before returning by the same general approach or by a short loop variant.

Why it is essential

Pumlumon is the defining summit of the Cambrian Mountains and a major watershed. It represents the quieter, broader and more remote character of the Cambrian uplands.

Equipment

• Sturdy boots
• Waterproof and windproof layers
• Warm layer
• Map/GPS
• Compass
• Food and water
• Navigation backup
• Trekking poles recommended on wet or boggy ground

Hazards and notes

• This is a less engineered and more remote upland walk than the other routes in this catalogue entry.
• Mist, boggy ground and poor path definition can complicate navigation.
• Weather can change quickly; walkers should be prepared to turn back.

3. Glendalough Spinc and Glenealo Valley

Itinerary

The signed White Route climbs from the Glendalough valley past Poulanass Waterfall, then ascends a long stepped and boardwalked section to the Spinc viewpoint above the Upper Lake. The route follows the clifftop boardwalk before descending through blanket bog and heath into the Glenealo Valley, returning by rough track towards the lake and visitor area.

Why it is essential

This is the classic Wicklow day circuit. It combines Glendalough’s monastic valley, waterfall, lake views, cliff-edge boardwalk and open upland terrain in a single signed route.

Equipment

• Hiking boots
• Waterproof layer
• Warm layer
• Food and water
• Map/GPS
• Sun protection
• Full mountain navigation equipment in poor weather

Hazards and notes

• The route includes cliffs, steep ground, many steps and boardwalk sections that may be slippery when wet.
• Avoid cliff edges, crags and waterfalls.
• Check weather and daylight before starting.
• Dogs should be kept under control.
• Large groups and organised events may need to contact the park in advance.

4. Carrauntoohil via Devil’s Ladder and Zig Zags

Itinerary

The route leaves the Cronin’s Yard / Hag’s Glen area and follows the valley approach towards the foot of the Devil’s Ladder. The climb up the Devil’s Ladder is steep and loose, gaining the col below Carrauntoohil before the final summit slope. Many current descriptions recommend descending by the Zig Zags rather than returning down the Devil’s Ladder, reducing rockfall risk and erosion pressure.

Why it is essential

Carrauntoohil is Ireland’s highest mountain and the central summit of the MacGillycuddy’s Reeks. The Hag’s Glen, Devil’s Ladder and Zig Zags combination is the most recognised non-technical day route to the summit, though it remains a serious mountain day rather than a casual walk.

Equipment

• Sturdy boots
• Waterproof and windproof layers
• Warm layer
• Map/GPS
• Compass
• Food and water
• Emergency layer
• Headtorch
• Helmet may be considered for groups using the Devil’s Ladder because of loose rock and rockfall risk

Hazards and notes

• The Devil’s Ladder is steep, loose and eroded.
• Loose stones and rockfall are possible.
• River crossings can become problematic during or after rain.
• Poor visibility near the summit can make route-finding difficult.
• The route requires mountain experience and should not be navigated solely from a phone trace.

5. Diamond Hill Loop

Itinerary

The route starts beside the Connemara National Park Visitor Centre at Letterfrack and follows the waymarked Lower Diamond Trail before continuing onto the Upper Diamond Trail. The walk forms a figure-of-eight loop, climbing through open national-park terrain to the summit area of Diamond Hill before descending to rejoin the lower loop and return to the visitor centre.

Why it is essential

Diamond Hill is one of Connemara National Park’s signature walks. It gives a compact but varied hill circuit with panoramic views towards Tully Mountain, Kylemore Abbey and the Twelve Bens.

Equipment

• Hiking boots or grippy hiking shoes
• Waterproof layer
• Warm layer
• Water
• Navigation backup
• Standard hiking equipment in good weather
• Mountain hiking equipment in wind, rain or poor visibility

Hazards and notes

• The path is waymarked, but the upper section is exposed to Atlantic weather.
• Check the weather before starting.
• Dogs are welcome but must stay on the lead.
• Marked trails should be followed to protect habitats.
