Tucked away on the eastern coast of County Wicklow, the Glen Beach Cliff Walk offers one of the most breathtaking yet lesser-known hikes on Ireland’s East coast. Starting just a short stroll from the charming town of Wicklow, this coastal trail blends dramatic sea views, rugged cliffs, peaceful countryside paths and even a chance to spot wild seals. With no crowds.
The walk begins at Glen Beach, just south of Wicklow Harbour. From the car park, a narrow, well-worn path climbs gently along the cliff edge. As you gain elevation, the views open up across the Irish Sea, with sheer drops to the crashing waves below. It’s a walk that feels wild and invigorating, yet manageable for most walkers.
Not far along the trail, a detour leads down to Lime Kiln Bay, a peaceful cove often visited by a small colony of grey seals. Between August and April, this bay becomes a nursery for seal pups, which are sometimes seen lying quietly on the beach. These pups are often left alone while their mothers are out at sea hunting for fish, and although it may be tempting to get closer, it’s vital to maintain a minimum distance of at least 100 metres.
Approaching a seal pup can cause stress or alarm, and human presence may discourage the mother from returning, leaving the pup vulnerable to starvation. Observing from a distance helps protect the pups and ensures the seal colony remains undisturbed. Dogs must be kept on a lead at all times.
From there, the main trail continues south toward Wicklow Head, where a series of scenic cliffs leads to the old and new lighthouses. The route toward the 18th-century octagonal tower is slightly more rugged but well worth the effort for the panoramic views.
Trail Details:
Distance: 4–5 km for the loop, with an optional 2–3 km extension to the lighthouse.
Time: 1.5–2 hours including the lighthouse.
Difficulty: Moderate – mostly easy paths with a few uneven sections.
Getting There:
Wicklow Town is about 40 minutes south of Dublin by car, train, or bus. From the town center, head to South Quay and follow the road signs to Glen Beach, where you’ll find a small parking area with picnic tables. The trailhead starts at the end of the car park.
If you have time after your walk, don’t miss a visit to Wicklow Gaol, one of Ireland’s most atmospheric historic prisons. Located in the heart of Wicklow Town, this 18th-century jail tells the story of Ireland’s troubled past through immersive exhibits and guided tours. You’ll learn about political prisoners, famine-era hardships, and even alleged hauntings
