Although The Glen in Sligo looks like something whipped up in Photoshop, it’s very real and it’s intensely beautiful.
The Glen is a result of a natural phenomenon that took thousands of years ago, but more on that in a moment.
In the guide below, you’ll discover how to find the entrance to The Glen (this can be tricky) to what to expect when you arrive.
Some quick need-to-knows before visiting The Glen in Sligo
A visit to The Glen isn’t as straightforward as a visit to some of the more popular places to visit in Strandhill, as its entry point is almost hidden. Here are some quick need-to-knows.
You’ll find the Glen hidden away from view on the side of the majestic Knocknarea, a huge, flat-topped rock formation. Situated in County Sligo, the mountain is on the Coolera Peninsula, around 7 km south-west of Sligo Town, and just south of Strandhill.
2. A natural phenomenon
No one knows for sure how the Glen was created. Theories range from supernatural forces creating a haven for the fey, to the formation being the result of an earthquake. One of the more popular theories is that it was formed by a glacier during the last ice age. While the walls of the Glen look man-made, they’ve been hewn from the rock naturally, creating something far more spectacular than man might dream up!
3. Like something from Lord of the Rings
Stepping into the Glen transports you out of the modern world, into a peaceful, green and natural land that feels a million miles away. Tall walls of mossy rock trickling with water surround you, while an array of trees, shrubs, and ferns creep up from the ground. The sounds from the world outside are silenced, leaving you alone in this fairy tale wonderland.
Finding the entrance to The Glen at Knocknarea
Finding the entrance to The Glen in Sligo can be a bit of a challenge. There are no sign posts or markers, but if you know what to look out for, you’ll find it eventually.
If you’re driving you need to aim for the area shown above (here it is on Google Maps). You’ll know you’ve reached it when you see the white well (yellow arrow above).
The entrance point is now near impossible to see, as the hedge and trees next to it are so overgrown. However, you’ll find it if you rummage around where the red arrow is pointing.
What to expect from a visit to The Glen
There are several reasons why an early-morning visit to The Glen is one of our favourite things to do in Sligo (the picture above should give you a good idea why, though!).
Nature lovers will adore The Glen and the fascinating plant life it’s home to. You’ll find a veritable smorgasbord of trees, shrubs, ferns, and moss to revel in, such as oak, pine, hazel, holly, beech, and plenty of ivy. One of the most impressive things is the height the ferns and nettles reach within the Glen — it’s almost like magic! Besides plants, there are plenty of intriguing critters that call the Glen home, such as lizards, beetles, butterflies, and rabbits.
A magical place
Whatever caused this cleft in the mountainside to appear, it certainly feels magical! Running just under a mile into the side of Knocknarea, The Glen is around 40 ft wide throughout much of its length, with natural stone walls reaching heights of around 60 ft. The result is a chasm that cuts out the sound of the modern world, replacing it with soothing trickling water, bird song, and the wind breathing through the trees.
A hidden gem
The Glen truly is a hidden gem, well off the beaten track. Since it isn’t signed at all, very few visitors to Sligo know about it. Finding it is difficult, but when you do, you’ll be glad you did. It’s supremely peaceful, and offers solitude and a break from our busy modern world.
The Glen walk
While there’s no official, marked trail, The Glen is a superb place for a gentle walk, and you can walk from the start to the end of The Glen in around 20 minutes (so allow at least 40 for the full walk).
Once you’ve found the gate that marks the entrance to The Glen, follow the path along for a short distance, until you find yourself surrounded by sheer rocky walls.
Once you’re in the chasm, you can follow it for around 3 quarters of a mile. If you’re a little claustrophobic you may find it slightly oppressive, but on the whole there’s plenty of space and light.
Indeed, the chasm reaches widths of up to 70 ft in some areas, and it feels amazingly tranquil. A good pair of waterproof boots are recommended, especially after rain.
All the water from the mountain trickles down into The Glen, and even on a sunny day you can hear the rocky walls weeping. There are few walks in Sligo that can go toe-to-toe with this one.
