Tarn Hows Walk — Tom Gill Waterfalls Circular

Q: How long is the Tarn Hows walk?

It depends which version you do. Our full circular from Glen Mary , climbing past the Tom Gill waterfalls, is 6.35 km (3.94 miles) with 181 m of ascent and takes around 2–2½ hours — the GPX is free to download on this page. If you just want the flat loop around the tarn from the main car park, that's roughly 1.9 miles and takes most people 45 minutes to an hour .

Q: Is the Tarn Hows walk suitable for pushchairs and wheelchairs?

The path around the tarn itself is flat, firm and wide , and is one of the most accessible walks in the Lakes — the National Trust even offers all-terrain Tramper scooters from the main car park. Our route is different: the climb up through the Tom Gill ravine has rocky, uneven steps and is not suitable for pushchairs or wheelchairs.

Q: How high are the Tom Gill waterfalls?

The main fall drops around 10 metres (about 30 feet) through a narrow, wooded ravine, with a smaller cascade lower down. They're modest by Lakeland standards but atmospheric — and much fuller after rain.

Q: How was Tarn Hows formed?

Tarn Hows looks entirely natural but is largely man-made . In the 1860s the landowner James Garth Marshall dammed the outflow beck to merge smaller natural tarns into the single sheet of water seen today, and the surrounding woodland was planted. It later formed part of the Monk Coniston estate that Beatrix Potter helped pass to the National Trust.

Q: Are dogs allowed at Tarn Hows?

Yes, dogs are welcome, but must be kept on a lead — the area is grazed by Belted Galloway cattle and Herdwick sheep, and the tarn shoreline is a sensitive wildlife habitat.

Walk Description

The Tarn Hows walk is one of the Lake District's true crowd-pleasers — but there's more than one way to do it, and the version most people never find is the best. From the car park at Glen Mary you climb a shaded, mossy ravine alongside Tom Gill, the little beck that drains Tarn Hows down towards Coniston, passing not one but two waterfalls on the way up. The first is a modest cascade, easy to walk straight past; but as the trees close in and the gorge deepens, the main fall appears — a slender white ribbon of around ten metres dropping over dark, wet rock. It's no Aira Force, but tucked into its narrow cleft of woodland it has a quiet drama all of its own, and it's at its most atmospheric after rain or, as our photos show, under a hard winter frost.

Then comes the moment the whole walk is built around: you step out of the trees and Tarn Hows opens up in front of you — a broad, island-dotted sheet of water ringed by pines with the Coniston fells rising behind. It's one of the most photographed views in Cumbria, and for good reason. Our route makes a partial circuit of the tarn before slipping away from the crowds onto an old byway and dropping back down a quiet valley path past little Yew Tree Tarn to the start. If you'd rather skip the climb, you can drive to the main Tarn Hows car park and simply walk the flat, wide, buggy- and wheelchair-friendly loop around the water instead — we explain both options below, so you can pick the one that suits your day. Download the GPX, check the forecast, and give yourself time to linger by the tarn.

Starting Point National Trust Tom Gill (Glen Mary) car park, A593 north of Coniston (grid ref SD 321 999)

Key Landmarks Tom Gill waterfalls, Glen Mary, Tarn Hows, the Coniston fells, Yew Tree Tarn

01

Into Glen Mary

Leave the far end of the Glen Mary car park and follow the path up into the woods with Tom Gill tumbling along on your right. The climbing starts almost at once, but it's gentle and shaded, on a mix of made path and tree-root steps beneath oak and birch. This lower stretch is the prettiest part of the woodland — take it slowly and listen for the beck getting louder as the valley narrows ahead.

02

The Tom Gill Waterfalls

The first waterfall arrives as a broad little cascade sliding over bare rock — a pleasant enough sight, but only a warm-up. Keep climbing as the gorge tightens and darkens around you and the second, taller fall reveals itself: a clean white plume of roughly ten metres dropping through a slot in the crags. There are a couple of natural viewing spots here; the rock and the steps beside them stay greasy long after rain, so watch your footing and keep dogs and children close.

03

Out onto Tarn Hows

Above the falls the path eases and the trees suddenly fall away, and there it is — Tarn Hows spread out ahead, its wooded islands and reed-fringed bays backed by the Coniston fells. It's a proper "wow" moment after the enclosed climb, and a good place to pause before you join the busy shore path. Turn along the tarn to begin the circuit.

04

Around the Tarn

Follow the broad, well-made path that runs around the water. This is the stretch you'll share with families and day-trippers, and the benches dotted along it are perfectly placed for the views across to Wetherlam and the higher Coniston tops. Take your time reading the water — still mornings give the mirror reflections the tarn is famous for. Our route doesn't go all the way round; watch for where it peels off up to the left.

05

The Old Byway

Leaving the shore, a gate lets you onto an old byway that climbs gently away from the tarn and, almost immediately, away from the crowds. The character changes completely — bracken, scattered thorn trees and open views one minute, cool conifer plantation the next. It's an easy, quiet stretch of walking, and a good chance to feel like you've got the fellside to yourself again.

06

Yew Tree Tarn and Back

The byway brings you down to a quieter valley path that leads back towards the A593. On the way you pass Yew Tree Tarn, a small, dark, dam-made pool that's easy to miss and well worth the look — another mirror on a calm day. A final short stretch of path returns you through the trees to the Glen Mary car park where you started.

Route Essentials

Two ways to walk it: Our route is the fuller 3.94-mile circular from Glen Mary, climbing past the Tom Gill waterfalls before reaching the tarn — more rewarding, but with a rocky, uneven ascent that isn't suitable for pushchairs or wheelchairs. If you just want the famous view with the least effort, drive instead to the main Tarn Hows car park and walk the flat, wide, roughly 1.9-mile loop around the water, which is buggy- and wheelchair-friendly. Same tarn, very different walk.
Parking: The Glen Mary car park sits right on the A593 (grid ref SD 321 999) — sat-nav postcodes for this stretch don't land you exactly at the entrance, so head for this Google Maps pin instead. It's pay-and-display, and the National Trust car parks in this area typically take payment by card or the JustPark app rather than cash — National Trust members park free by scanning their membership card or checking in on the app. Check current tariffs on the National Trust website before you go — prices change and we don't want to quote you the wrong figure.
Terrain and accessibility: The path around Tarn Hows itself is flat, firm and wide — genuinely one of the most accessible walks in the Lakes, and the National Trust offers all-terrain Tramper mobility scooters to use around the tarn from the main car park (donations welcome). Our route is different: the climb up through the Tom Gill ravine is on uneven, rocky, sometimes slippery steps and is not suitable for pushchairs, wheelchairs or Trampers. A baby carrier beats a buggy if you're set on the waterfall climb.
Toilets and refreshments: There are toilets at the main Tarn Hows car park; there is no café at the tarn itself, though a refreshment van often parks up there in season. Coniston, a couple of miles away, has a wide choice of pubs and cafés for afterwards.
Dogs: Welcome, but keep them on a lead — Tarn Hows is grazed by Belted Galloway cattle and Herdwick sheep, and the shoreline is ecologically sensitive.
Swimming: Tarn Hows is not a swimming spot — the water and shoreline are protected for their sensitive plant and wildlife habitats, and swimming is discouraged. Enjoy the reflections from the bank instead.
Best in frost or after rain: The Tom Gill waterfalls are slight in a dry spell but come alive after wet weather — and, as our winter photo shows, look their most magical under a hard frost. Tarn Hows itself is at its best on a still morning for the reflections, or in autumn when the surrounding trees turn.

Best Time to Visit

The Tom Gill waterfalls need water to impress, so this walk is best after a spell of rain — or, for something special, under a hard winter frost, when the falls rime up with ice. Tarn Hows itself is loveliest on a still, clear morning, when the pines and fells mirror perfectly in the water, and again in autumn as the surrounding trees colour up. As one of the most visited spots in the Lake District, the tarn gets genuinely busy on summer weekends and in school holidays — arrive early or come midweek for quieter paths and an easier time parking.
