A cavern deep in the woods, hewn out of the rock during the search for slate. A sloping pillar, rather like the Leaning Tower of Pisa, holds the roof of the cavern up. A pool of water that's cold as ice even on a warm summer's day, lies to one side. A window high on the side provides a little soft light, and gives a view down onto a largely historic industry. This is Cathedral Cavern.
The most dramatic way into the cavern is as the miners would have done, via a 100m (110 yards) long dark and damp tunnel. After the tunnel and a little scrambling over rock debris you find yourself in an open to the sky pit. Over to the right is the window into the main cavern. Scrambling down a short smooth rock step brings you to another much shorter tunnel which then takes you into the Cathedral itself.
Bring a torch, preferably a head-torch, you will not be able to walk through the tunnel without one.
On 3rd July Coniston MRT reported that:
There has been a large rockfall at Cathedral Quarry, and the National Trust has consequently closed the upper parts of the quarry and the tunnels until the area has been inspected. A boulder the size of a large car had collapsed. The bottom main chamber (the Cathedral) remains open at this time. Visitors and climbers need to be aware that access is restricted, and comply with posted signs on-site.
So at the moment you will not be able to do this walk exactly as described here but there is still access to Cathedral Cavern. Please rely on local signage.
This walk starts at the small parking area at Tilberthwaite just north of Coniston village.
The work we do on this web site, both researching and writing up walks, takes a lot of our time but doesn't make us a great deal of money. The main way we fund this work is by selling our walks as PDFs for printing. Please use the "Buy walk in Adobe/PDF format to print or for your phone or tablet" link on the walk page to do that.
If you have already purchased the walk then you if you are logged in you can find it in your rucksack (link top right on any page) in a format suitable for printing.
Thank you for your support

Continue along the road from the parking area towards High Tilberthwaite Farm. Go through the farmyard keeping right, ignore the track to the left which climbs steeply. Bear right to exit the yard through the gate onto a hard surfaced track. Follow this bridleway, generally NNE. Over to your right, across Pierce How Beck, the spoil heaps are from the Hodge Close quarries. Keep right, but remain on the obvious track.
Continue through the gate beside the aptly named Moss Rigg Wood. In front of the isolated cottage (Brooklands Cottage) the track swings right. In just 70m (77 yards) go through the gap stile in the wall to your left noting the small sign just the other side! Follow the rough eroded path ahead up into the trees, swinging left. In only 30m (33 yards) bear left off the remains of the path into a clearing. This is the top of a spoil heap and to your right is the long tunnel entrance. This is why you need a head torch.
Follow the way through the tunnel. A side-tunnel is gated so there is little to explore there. Reaching the daylight at the far end keep right and clamber over the rocks, keeping to the right. Reaching another level area with a central bowl, keeping children and dogs close by, bear right to go through the gap in the fence to view the cavern from the window. The drop in front of you is sheer!
Return to the bowl and descend to the right over rocks to the lower level. A rocky step is well marked by the passage of boots but can be a little slippery when wet. Go through the short section of tunnel into Cathedral Cavern. Beware the pool of water shelves gently, then drops considerably. So keep away from it.
The other side of the pillar is another short tunnel, the exit.
Back in the daylight, bear left down to the gate and stile, and onto the track. Bear left again. Slater Bridge can be seen over to your right. At Low Hall Garth Hut the track turns left and climbs steeply to High Hall Garth.
Continue on approximately 200m (220 yards) to a junction and signpost amongst open ground. Turn sharp left, signposted to Tilberthwaite 1mile. Climbing steadily, the track is initially severely washed out. Soon passing beside another area of old quarries and an area known as Knotts, named after the proliferation of small bumps, it drops back into High Tilberthwaite Farm yard at the 'left gate'.
Bear right, leaving the yard by the road and return to the parking area.
