Peering over Thirlmere Reservoir and the Lake District’s Northern Fells, Thirlmere Infinity Pool has become a big hit on social media, making it one of the more famous Lake District walks. The natural infinity pool, formed by cascading waters from the gushing waterfall above, lets you enjoy stunning views as you soak in its refreshing waters.

Although the route is relatively short and easy, the walk up to the waterfall can be a little tricky in parts, with some rocky ground and a short but steep climb to the top. However, anyone with a reasonable level of fitness and the right walking gear, shouldn’t find it too much of a struggle. I would advise visiting on a dry day as the rocks can be quite slippery following heavy rainfall.

Thirlmere Infinity Pool Walking Route

  1. Park at Legburthwaite, just off the A591, which is operated by United Utilities and provides amenities such as toilets and picnic areas.

5. Pass through the gate and follow the path diagonally up and to the right. This section of the trail follows a gradual ascent and steers you through several gates. Make sure you stop to take in the fabulous views of the Northern Fells that begin to open up as you climb higher.

6. You soon reach a set of smaller waterfalls. Turn right here and you’ll see a wooden sign saying Public Footpath.

7. Continue right at the sign and follow the drystone wall. This section starts to get a little rockier so watch your footing. As you ascend, you’ll see several fells to your right, including High Tove, Armboth Fell, and Low Saddle.

8. Pass through another gate and along the narrow footpath and soon Thirlmere Reservoir will come into sight.

9. After approximately 700 metres, you will reach a small wooden bridge. From here, you can catch your first glimpse of the waterfall that creates the Thirlmere Infinity Pool. This is a great spot to pause and listen to the sound of rushing water and take photos of the Lake District landscape. There’s also a great view of Raven Crag looming above the reservoir.

10. Cross over the bridge and head up the bank with the waterfall on your left. This is the steepest part of the Thirlmere Infinity Pool walk and while it requires careful navigation, it’s manageable with caution and provides an exciting challenge. Take your time and ensure you have a firm footing as you ascend.

11. Once you’ve climbed the steep section, you’ll arrive at the Thirlmere Infinity Pool. The pool is situated above the first series of waterfalls and another waterfall feeds into it, creating one of nature’s most beautiful wild swimming spots. I say wild swimming, but it’s more of a plunge pool with an incredible view.

You can access the pool from either side of the waterfall, but you do have to be cautious clambering down the rocks as there are some steep drops.

If you want to get some impressive photos, continue above the waterfall to capture the infinity pool overlooking Thirlmere Reservoir.

Tips for Visiting

Timing Your Visit

The best times to visit Thirlmere Infinity Pool are early morning or late afternoon. During these times, you’ll likely encounter fewer visitors, allowing you to enjoy the serenity of the pool in peace. Also, the lighting during these hours enhances the beauty of the landscape, making for a picturesque experience.

Safety First

Safety is paramount when visiting the infinity pool, especially given its location above the waterfall. Avoid visiting after heavy rainfall, as the increased water flow can make the area more hazardous. Always be mindful of the slippery rocks and ensure you have a firm grip when navigating the area.

Leave No Trace

Preserving the natural beauty of Thirlmere Infinity Pool is essential. Take any rubbish with you and leave no trace of your visit. This practice ensures that future visitors can enjoy the pristine surroundings just as you did. Respect the environment and contribute to the conservation of this stunning spot.
