What Exactly Is a Limestone Pavement?

A limestone pavement is one of the strangest landscapes you can walk across in Britain: a bare, water-scoured expanse of grey rock split into flat blocks (clints) separated by deep, narrow fissures (grykes). The blocks were shaped by glacial ice scraping the surface, and the grykes were widened over thousands of years by rainwater dissolving the limestone along its natural joints.

England's finest examples sit inside the Yorkshire Dales National Park, with particularly good stretches around Malham, Ingleborough and the flanks of Kingsdale and Chapel-le-Dale. Walking on pavement feels unlike anything else — part pavement, part maze, with a curious hollow ring underfoot where the rock is thin. It also demands care, because what looks like indestructible stone is a habitat that takes centuries to repair.

Classic Routes Where You'll Meet It

You do not need to go looking for a geological site; pavement turns up on many of the Dales' best-loved walks. A few reliable options:

• Malham circuit — about 8 miles from Malham village, taking in Janet's Foss, Gordale Scar, Malham Tarn and the top of Malham Cove. The clint-and-gryke surface above the cove and beside the tarn is superb, and the return down the steps gives you the classic view of the amphitheatre.
• Twistleton Scar from Ingleton — a steady 5-mile there-and-back past Fell Lane, with wide pavement slabs, big skies and Ingleborough filling the horizon. Easy to extend over to White Scars if the weather is kind.
• Clapham to Gaping Gill and Ingleborough — a longer day of 9 to 11 miles via Trow Gill, the vast pothole of Gaping Gill and the plateau above. The ground here is a patchwork of pavement, shaken limestone and thin turf.
• Scales Moor above Chapel-le-Dale — arguably the largest continuous area of pavement in the country, reached from Ribblehead or Chapel-le-Dale. Bring a compass; the grykes make the ground confusing in mist.
• Winskill Stones near Settle — a short, rewarding wander above Langcliffe with excellent pavement flora and a grand view down Ribblesdale.

The Hidden Garden in the Grykes

Grykes are miniature sanctuaries. They stay cool and damp, they shelter plants from wind and from grazing sheep, and their deep shade suits species that once grew across a much more wooded Britain. Peer into one and you may find hart's-tongue fern, its strap-like fronds hanging vertically, along with rigid buckler-fern, wall rue and maidenhair spleenwort.

Flowering plants are just as special: lily-of-the-valley, wood anemone, angular Solomon's-seal, dark-red helleborine and, in the best sites, rarities such as hoary rock-rose and spring sandwort. The clint tops carry their own community of mosses, lichens and blue moor-grass. Scar Close, near Ingleborough, is fenced against grazing and shows what this habitat looks like when nothing nibbles it — the difference is startling.

Walking Well: Protecting a Fragile Habitat

Limestone pavement is listed as a priority habitat, and a bootprint on a mossy clint can last decades. Small habits make a real difference:

• Stay on the path across open pavement, and walk on bare, solid clints rather than the vegetated edges where the flora lives.
• Never step into a gryke or lever at loose rock — gryke walls are the growing medium, and collapsed stone smothers plants.
• Keep dogs on a short lead from March to July. Ground-nesting birds such as curlew, lapwing and skylark use the surrounding limestone grassland, and ewes with lambs are everywhere.
• Take nothing. Removing rock, plants or fossils damages the site and is illegal on protected land.
• Use gates, not walls. Drystone walls here are both livestock fencing and wildlife corridors, and climbing them loosens stones.
• Park considerately in villages such as Malham, Clapham and Austwick, and pay where there is a charge — car parks fund the paths that keep feet off the pavement.

Weather, Kit and Timing

Pavement is beautiful in sunshine and treacherous in rain. Wet limestone is greasy, so grippy boots with a stiff sole are far better than soft trainers. Add a paper map and compass: the relevant 1:25,000 Explorer sheets cover the area well, but GPS batteries fade and the gryke field can swallow your sense of direction in twenty yards of mist. Pack waterproofs whatever the forecast, plus water — the plateau has almost no reliable streams, as the rain vanishes straight down the swallow holes.

Late spring and early summer give you the wildflowers and long daylight; autumn brings golden light and quieter paths; winter can be stunning but the pavement often hides under snow, so kick steps with care and turn back if the cloud drops. Early starts beat the crowds at Malham Cove and Gordale in particular.

Walk slowly. The pleasure of the Dales' limestone is in the detail at your feet — a fern in a crack, a lime-loving orchid, the clink of boots on rock — and in leaving it exactly as you found it for the next pair of boots along.
