Visit Lough Ouler

A wild lake, accessible only on foot!

Let’s face it: Lough Ouler is still a relatively unknown spot for tourists. But there’s a good chance it will become a much sought-after attraction in the years to come! So why not make the most of it now, and avoid the world!

Before you start, Lake Ouler lies at the foot of Tonelagee Mountain (Tóin le Gaoith). It is the 3rd highest mountain in the National Park, and the 33rd highest in Ireland.

The lake can be admired from the top of this mountain. But beware: there are no trails to guide you, and the mountain has a reputation for being particularly exposed to the wind. You’ll need stamina, a good level of hiking ability and the ability to handle steep slopes.

For a good walker, the round trip takes around 3 hours.

Where to start?

The hike can begin after parking in a special parking lot on the side of Glenmacnass waterfall. Free of charge, it is located on the R115 (the Old Military Road). Don’t worry: the parking lot is safe and provides a fairly straightforward start to the climb.

Before setting off, remember to bring hiking boots, a backpack with water, sandwiches (the perfect opportunity to try an Irish cheddar sandwich!), a windbreaker and a warm sweater.

All you have to do is progress at your own pace: cross the river, then follow the edge of the wood, and start climbing the mountain. Continue straight on, then take the extremely muddy path to the highest point. The lake should then be on your right.

The landscape is striking, contrasting heather, greenery and the deep waters of the lake. You’ll be overlooking the mountains of the National Park: a real feast for the eyes, giving you the impression of being alone in the world, in the middle of the wilderness. It’s the perfect way to reconnect with nature and admire this heart-shaped lake!
