A few weekends ago, I found myself craving an adventure—a proper escape from the usual routine. That’s when a friend mentioned Lough Ouler, a heart-shaped lake tucked away in the Wicklow Mountains. I’d seen photos on Instagram, but they didn’t prepare me for what was ahead.
The trail starts quietly, weaving through rugged hills and heather-covered paths. With every step, the noise of everyday life fades, replaced by the sound of nature—birds, the crunch of your boots, and the distant rustle of the wind.
And then, just when you think the climb couldn’t offer anything more, the view of Lough Ouler opens up. It’s peaceful, untouched, and a reminder of why places like this are worth the effort.
Quick need-to-know tips for Lough Ouler
Location
Lough Ouler is located in the heart of the Wicklow Mountains, just a short drive from Dublin, making it an ideal day trip for anyone looking to explore Ireland’s natural beauty.
I’ve included the Google Maps location below for easy navigation.
How to reach Lough Ouler?
The best way to reach Lough Ouler is by car. You can drive up here or even rent a car from Europe Car or Budget Car.
I have already mentioned the location on Goggle Map above. There’s also parking options. The road is so scenic, but please make sure that you drive safely as the road is narrow, allowing for two cars to pass at a time. Don’t speed up and be cautious as cars are coming up from the other side.
Parking at Lough Ouler
Depending on the hiking route you choose, there are two parking options at Lough Ouler. The spaces are relatively big, so you won’t have to worry about parking.
However, during the peak summer season when you expect more people to explore, it may fill up quickly. But in that case, you can go up to the next parking as the only difference is that you end up picking the longer loop.
- Wicklow Gap Car Park: This is the most popular parking spot for those hiking to Lough Ouler via Tonelagee. It offers a large, free parking area, with easy access to the trailhead.
- Glenmacnass Waterfall Car Park: If you’re taking the more challenging circular route from Glenmacnass, you can park at this car park, which is close to the waterfall and the starting point for the hike.
