Best trails in Wicklow Mountains National Park

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.

One of the most beautiful trials of rrh Wicklow mountains

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.
