The Bridia Valley is a beautiful and isolated area of Ireland. The valley is a cul-de-sac and the main attraction and reason for people visiting is the Kerry Way. Surprisingly, there is a great café called the Cooky Monster Café, which adjoins the Stepping Stone Guest House. Both are friendly, handy and well worth a visit.

One of the most incredible landscapes in all of Ireland. A series of lakes connected to each other, immersed in green mountains and fields of free-grazing sheep. Very easy trekking on a paved road, occasionally used by cars and horse-drawn carriages. In a couple of places you can reach the water of the lake and sit on the shore.

The journey through this gorge is a special adventure, where you will repeatedly pass by "lost places" - abandoned paths, mystical corners and old, overgrown fences that tell of times gone by. The silence here is overwhelming, only occasionally interrupted by the gentle rustling of the wind or the bleating of sheep. It is a place that makes you feel far away from the modern world - perfect for anyone who wants to experience nature in its wildest form.

This hike takes you through a breathtaking gorge, which opens into the vast, tranquil landscape of the lake through the "gate." The narrow path winds between steep rock faces, offering you repeatedly impressive views of the clear water and the surrounding hills. You can literally feel nature setting the pace here – the calm waves of the lake, the green vegetation stretching over the rocks, and the recurring feeling of vastness. The path is narrow and a bit challenging in places, but that only makes the hike all the more exciting. I particularly liked the small bridges that repeatedly cross the route – perfect for pausing to admire the scenery. Andy's tip is a good one: There are numerous photo spots along the route that you shouldn't miss. One tip: Even though the route is quite popular, you can usually find a quiet corner to take in the scenery. Early morning or late afternoon is the best time to fully enjoy the hike and escape the crowds. It's also worth exploring the route on foot or in one of the traditional horse-drawn carriages – this way you avoid the busy roads and experience the area more intensely. For me, the "Gate & Lake" route is a place of contrasts: from the narrow passage through the gate to the vast, tranquil lake landscape. It's a hike that's not only physically challenging but also offers repeated moments of peace and reflection. Perfect for connecting with the wild beauty of Ireland.

Here you should hike or (at best) take one of the horse-drawn carriages. With the car it's stupid for everyone.

The MacGillycuddy's Reeks are characterized by a glaciated landscape, featuring deep U-shaped valleys, corries (bowl-shaped hollows), and sharp ridges. You'll encounter stunning glens and gullies, including the dramatic Hag's Glen, and various lakes such as Lough Caillí and Lough Coomloughra. Many areas offer spectacular viewpoints and rivers like the Caragh River.

You can find more hiking options in the Hiking in the MacGillycuddy's Reeks guide.
The terrain varies from dirt roads and sheep pastures in areas like the Black Valley to steep, rocky gullies such as the Devil's Ladder. Some paths, like Through the hollow way, follow old routes that can be overgrown. Hikers should be prepared for rugged, wild landscapes, and waterproof shoes are often recommended, especially in secluded areas.
Key landmarks include the Gap of Dunloe, known for its photo opportunities, and the Black Lough and Stone Bridge, offering dream landscapes. The Olde Butter Road, passing through a natural hollow way, leads to a wide plateau with spectacular views towards Killarney National Park. The Eagle's Nest Corrie on Carrauntoohil's northeast face is also a significant geological landmark.
While many routes are intermediate to difficult, some areas offer more accessible experiences. The Gap of Dunloe can be explored by hiking or horse-drawn carriages, making it suitable for a wider range of visitors. The Black Valley offers quiet walks, though some parts may require waterproof footwear. Always check specific route details for suitability.

The best time to visit generally depends on your activity. For hiking and exploring the glens and gullies, late spring to early autumn (May to September) typically offers more stable weather conditions, longer daylight hours, and milder temperatures. However, weather in the mountains can change rapidly, so always be prepared for all conditions regardless of the season.
The Devil's Ladder is a well-known, steep, and rocky gully located in Hag's Glen. It serves as the most popular, albeit challenging, route to the summit of Carrauntoohil, Ireland's highest peak. While direct, it can be hazardous, especially when wet, as it transforms into a slippery waterfall. Its iconic status makes it a frequented path for mountaineers.
Yes, several glens and gullies provide access to Carrauntoohil. Hag's Glen is a primary access point, leading to routes like the Devil's Ladder and Brother O'Shea's Gully. These routes offer different levels of challenge for those aiming to reach Ireland's highest point.
The Coomloughra Horseshoe is a highly regarded 15-kilometer ridge walk that encompasses all three of Ireland's 1,000-meter peaks: Carrauntoohil, Beenkeragh, and Caher. This classic route, known for its sustained height and breathtaking views, passes through the U-shaped valley of Lough Coomloughra, showcasing the powerful glacial activity of the region.
