Best trails in Wicklow Mountains National Park
The Wicklow Mountains National Park encompasses approximately 23,000 hectares of Wicklow Upland, characterised by blanket bogs, rugged mountain peaks, and enchanting valleys. The park offers wonderful routes whether you’re looking for a leisurely walk or a more challenging trek. Glendalough Valley is one of the most popular destinations in Wicklow Mountains National Park, with many activities to be enjoyed in the area. The mountains south of this valley are excellent ways to extend the hike, with great routes leading up the Spink, Mullacor, and Lugduff SE Top, all offering spectacular panoramic views of the surrounding Wicklow Mountains landscape. Another iconic peak in the park is Scarr Mountain, situated on the eastern rim of the Wicklow Mountains, about five kilometres north of the more well-known and renowned Glendalough Valley. Several tranquil lakes are interspersed throughout the Wicklow Mountains, including Lough Ouler, a beautiful heart-shaped lake on the northeastern side of Tonelagee, formed by glacial erosion, or Lough Tay, which is also sometimes referred to as Guinness Lake due to its shape resembling a pint. The Wicklow Mountains are traversed by the Wicklow Way, which extends over 130km (80 miles), linking Marley Park in Dublin to the village of Clonegal, and winds its way through dense woodlands, across heather-clad moors, and along tranquil lakes. Other iconic trails include Saint Kevin’s Way, a pilgrim path marked by yellow waymarkers that follows the 6th-century Saint Kevin’s walk from Hollywood to Glendalough Valley, where he founded the monastic settlement. The Wicklow Mountains National Park weaves together Ireland’s cultural heritage and natural beauty, offering wonderful adventures amidst unique, untamed wilderness with expansive vistas.
The Wicklow Mountains are located just south of Dublin and are easily accessed from the city. Many places in the Wicklow Mountains are only accessible by road however (car or bicycle), and these roads are shared with cyclists, so take care as you make your way along the winding roads.
Please keep in mind that dogs must be kept on leads to protect wildlife.

Trail reviews for Wicklow Mountains National Park
Nice trail if you want something a little longer and not hugely strenuous. I followed the route exactly and my total elevation was 475m and took just 2 hours (fast pace). It’s mostly a wide stony path through coillte forest but nice stretch along the Wicklow way and nearer to ravens rock and Prince William’s seat is more boggy and rocky. Few trees to navigate around but very manageable. Really nice views pretty much all of the way of Dublin and all of the Wicklow mountains and hills.
Spinc and Glenealo Valley Trail – Wicklow Mountains Location: Glendalough, County Wicklow Trailhead: Glendalough Upper Lake Car Park Distance: ~9.5 km loop Time: 3–4 hours depending on pace and stops Difficulty: Moderate (steep sections, boardwalks, and rocky paths) Highlights: Breathtaking lake views, boardwalks along the cliffs, deer sightings, and a dramatic glacial valley --- Parking Pro Tip The trail starts from the Glendalough Upper Lake Car Park. This car park officially opens at 8:00 AM, and has two types of gates: A traditional metal rod gate, And an electronic paid gate with a lift barrier. If you arrive before 8:00 AM, the physical metal gate may look locked, but it usually isn’t. Just gently pull it aside to its resting position (don’t force it!), then walk up to the electronic paid gate and give it a gentle pat—the system should activate and let you through. This is super handy for early hikers trying to beat the crowds or catch the sunrise. Note: You’ll still need to pay for parking at the machine or app, even if you arrive early. --- Trail Experience Starting off, you’ll pass through a wooded area before climbing up steep wooden steps (this is where the heart rate kicks in!). Once you reach the boardwalk at the top of the cliffs, the view over Glendalough’s Upper Lake is absolutely stunning—a perfect photo stop. The trail continues along the boardwalk with incredible views and then drops into the Glenealo Valley, where you might spot wild deer grazing in the open. From there, the trail loops back down alongside the Glenealo River, with waterfalls and serene scenery as you descend into the valley. --- Tips Wear sturdy hiking boots—some rocky sections and wet boardwalks can be slippery. Bring layers—weather can change fast in the Wicklow Mountains. Start early—not just for parking, but to avoid busier midday crowds. Respect the wildlife—the deer are lovely to see, but keep your distance. --- Final Thoughts The Spinc and Glenealo Valley Trail is one of the best day hikes in Ireland—diverse, scenic, and full of peaceful nature. Whether you’re an experienced hiker or just love a good outdoor adventure, this loop is well worth the effort.

The trail is amazing, and promises some great views of the Wicklow mountains - which we unfortunately didn’t get to see because of the weather - foggy, cloudy, rainy. However, it’s a moderate challenging hike and good water proof shoes are an absolute must. It was quite boggy as well. I’d happily go back to this trail in better weather.
