Glendalough hike is the most popular route in Wicklow Mountains leading above the glacial valley, which is home to two stunning lakes, historic monastic ruins and a network of trails that wind through enchanting woodlands and rugged peaks.

Over the last few years I hiked most of the trails in Wicklow Mountains National Park. Glendalough is a fantastic starting point for a number of walking routes in the valley at all levels of difficulty.

How long is the Glendalough hike?

First of all there are two loops: 

  • Glendalough Upper Loop
  • Lower Lake Loop is a convenient walk for everyone, it takes about 1.15h and it’s only 4.5km.

Glendalogh Lake is a very popular tourist destination, don’t be surprised with crowds (especially on weekends). Bring rainproof clothes, as Wicklow weather can change rapidly (just like in whole Ireland). 

How hard is the Upper Glendalough hike?

One of the most popular hikes is Glenealo Valley Loop, which typically takes around 4-5 hours to complete. This moderate hike treats hikers to panoramic views of the Upper Lake and the surrounding mountains, making it a must-do for those seeking a rewarding adventure without an all-day commitment. 

The Spinc Ridge is a more demanding hike but it’s my favouurite view of the shimmering lakes. This is a perfect route for adventurous hikers looking for a more strenuous  experience and challenging route. Be prepared for a rocky terrain on the way to the waterfalls. 

Glendalough hike starting point.

Drive to Glendalough Visitor Car park or Glendalough Upper Lake Car Park. There are plenty of spaces to leave your car (day fee is something like 4 Euro).

One of the most spectacular trails is a loop around Glendalough Upper lake through Miners Village. Hiking up is rewarded by stunning views of the Glenealo Valley. I highly recommend hiking the full loop which is around 10 km (takes about  4 hours) depending on a weather coditions and your fitness level. The weather can be very ungreateful in the valley, it is often rainy with a limited visibility. 

DOGS: This walk is suitable for dogs (mine always loved it!) but many trails in Wicklow Mountains do not allow dogs – so pay attention to signs ‘No dogs allowed’. 

How to spend a day in Glendalough.

Glendalough hike is one option but guided Glendalough walks are extremely popular in the area. Day tours will take you on an enjoyable trip across ireland rolling countryside, Wicklow Mountains and medieval monastery of Glendalough.

If you are planning to explore Dublin, you might want to use Go City All Inclusive Pass with + 40 Attractions, you save up to 50% on major attractions including: Guinness Storehouse, us tour, Museums and more.

There is no entry fee to Wicklow Mountains National Park. You will find some coffe and snack stalls at the entrance.

From the Glendalough Upper Lake Car Park there are number of marked trails, which start from half an hour walks up to the 12 km full loop. Remember that weather conditions may be slightly different (or even very different) from the starting point. I experienced heavy rain and wind while doing Gledalough hike. Always carry warm clothes, rain & windproof coat and good hiking shoes. It can get really windy in the area.

If you are considering hiking Lugnaquilla the highest peak in Wicklow Mountains, here is some good advice (I’ve done it in tough winter conditions and mild spring temperatures).

Wicklow Way Hike.

For those seeking a longer and more challenging hike – the Wicklow Way offers a multi-day trek through the mountains, including sections that pass through Glendalough.

This long-distance trail spans approximately 129 kilometers and can take around 5 to 7 days to complete in its entirety. However, you can choose to explore specific segments of the Wicklow Way that pass through Glendalough.
