La Coupée Sark: the complete guide to the iconic isthmus walkway

What is La Coupée?

La Coupée is the narrow concrete isthmus that connects Big Sark — the main body of the island — to Little Sark in the south. It is the most recognisable feature of Sark, one of the British Channel Islands (Crown Dependencies in the English Channel, not to be confused with the Channel Islands National Park in California), and one of the most dramatic short walks in the British Isles.

The walkway measures approximately 90 metres long and less than two metres wide at its narrowest point. On both sides, the cliff drops almost 100 metres to the sea below. Iron railings run the full length on each side, installed after the Second World War. The surface is concrete, generally in good condition, and perfectly safe to cross. But the combined effect of the narrow width, the sheer drops, and the vertiginous view straight down to the sea is something no amount of description fully prepares you for.

La Coupée is not just a view. It is a passage — a physical crossing between two distinct parts of an already extraordinary island — and it gives access to the quieter southern half of Sark that many day-trippers never reach.

The history of La Coupée

The ridgeline connecting Big Sark to Little Sark has been used as a crossing for centuries. Before the present concrete walkway existed, the passage was a narrow dirt path along the same ridge, without railings, and dangerous in strong winds. Historical accounts describe local children being tied to ropes to prevent them from being blown off the edge on their way to the school on Big Sark.

The concrete causeway was constructed in 1945, at the end of the Second World War occupation of the British Channel Islands. German forces had occupied Sark — as they had occupied all the Channel Islands — from 1940 to 1945. The construction of the current La Coupée walkway was carried out by German prisoners of war under the supervision of the Red Cross in the months following liberation, using forced labour to install the concrete surface and the protective railings.

This history adds a particular layer to the La Coupée crossing. The structure beneath your feet was built by men who had until very recently occupied the island. The railings that prevent you from falling were installed by the same workforce. It is one of the most tangible WWII heritage sites in the British Channel Islands — the more striking because it is not a museum or a monument but a piece of functional infrastructure still used daily.

Getting to La Coupée

La Coupée is located at the southern end of Big Sark, approximately 2 kilometres south of the village. There is one approach route.

Sark itself is reached by passenger ferry from St Peter Port, Guernsey. For full details on getting to Sark — including ferry schedules and what to do on arrival — see the Sark day trip from Guernsey guide.

From the harbour: take the tractor-trailer to the top of the harbour hill, then ride or walk south through the village and continue on the main road south. The road descends gently for the final kilometre before reaching the top of La Coupée. The full journey from the harbour to La Coupée takes approximately 45 minutes on foot or 20 minutes by bicycle.

From the village: straight south on the main lane. This is the same route as from the harbour, shorter. Allow 25-30 minutes on foot, 10-15 minutes by bicycle.

There is no other approach to La Coupée. The cliffs around the southern connection between Big Sark and Little Sark are sheer and inaccessible from sea level without a kayak. La Coupée is the only land crossing.

Bicycles: many visitors ride to La Coupée on hired bicycles from the harbour or village, park the bicycle at the top, and cross on foot. This is the recommended approach — the crossing is too narrow for comfortable cycling (though some cyclists do cross slowly), and the path into Little Sark on the far side involves some sections where the bicycle would need to be walked.

The crossing itself

The approach from Big Sark gives a view along the length of La Coupée before you step onto it. The ridgeline extends southward, with the drop visible on both sides and Little Sark visible as a green plateau on the other side. Most first-time visitors pause here before committing to the crossing.

The walkway is approximately 90 metres long. The iron railings are solid and are at a comfortable height for most adults. The concrete surface is flat and gives good grip in all conditions.

In calm weather: the crossing is straightforward and takes 4 to 5 minutes at a normal walking pace. You stop in the middle to look down on both sides. The drop on the western side goes directly to the sea; the eastern drop goes to a small valley that is also effectively inaccessible from below.

In wind: La Coupée becomes more challenging. The island is exposed to prevailing Atlantic weather, and wind can be strong even on days when the rest of the island seems mild. In strong wind (gusts over 30 mph), the experience is significantly more physical — you hold the railings, the crossing takes longer, and the vertigo is intensified. This is not dangerous if the railings are used, but it is not comfortable for everyone.

With children: children should be supervised and should hold the rail throughout the crossing. Younger children may wish to hold an adult’s hand. The crossing is completely safe with normal precautions.

With a fear of heights: La Coupée is genuinely vertiginous. If you have acrophobia, the crossing is difficult even though the railings are secure. Many people with moderate height anxiety manage it by focusing on the surface underfoot rather than the drop. If you have severe acrophobia, be honest with yourself before attempting it.

Little Sark: what is on the other side

Little Sark is the southern section of the island, separated from Big Sark by La Coupée and with its own character. It is less visited, quieter, and more remote-feeling despite being accessible from the main island.

The southern plateau: immediately beyond La Coupée, a lane continues south across a flat agricultural area. Small farms, stone walls, and a handful of buildings. The silence is notably deeper than on Big Sark.

The old silver mine: about 500 metres south of La Coupée, the remains of a nineteenth-century silver mine are visible on the western cliff edge. The mine operated briefly in the 1830s-1840s before the silver deposits proved insufficient for profitable extraction. The machinery is long gone but the excavations and some structural ruins remain, in a spectacular cliff-edge position.

La Grande Grève beach: the most compelling destination in Little Sark — a wide, south-facing sandy beach accessible by a steep descent from the southern plateau. The path down is clearly marked but involves a sustained descent of about 20-25 minutes and a similar ascent returning. This beach is tidal: it is only accessible at low tide. At high tide, the sea covers most of the beach and the lower section of the path.

For a day trip, visiting La Grande Grève adds approximately 1.5 hours to the La Coupée visit. This is possible if you arrive early on the morning ferry and move efficiently. Use the tide times tool to check Sark tidal conditions before making the descent.

La Coupée photography

La Coupée is one of the most photographed locations in the British Channel Islands. Some guidance for getting the best result:

The classic shot: stand on the Big Sark approach, slightly elevated above the start of the walkway, and shoot along the length of La Coupée with Little Sark visible at the far end. A wide-angle lens (16-24mm on full frame) captures the full width of the drop on both sides simultaneously. This is most effective with a person on La Coupée to provide scale.

The head-on shot from Little Sark: cross La Coupée and walk 50-100 metres into Little Sark, then turn and shoot back. From this angle, La Coupée appears as a narrow concrete bridge hanging between the cliffs. The sea on the western side and the valley on the eastern side frame the image symmetrically.

Light: La Coupée runs roughly north-south. East light (morning) illuminates the western face; west light (afternoon) illuminates the eastern face. Cloudy light is often most photogenic for the vertiginous drop shots, as it avoids harsh shadows that obscure detail.

Timing relative to ferry arrivals: day-trip ferries from Guernsey arrive around 09:50-10:30. Most day-trippers reach La Coupée by mid-morning, and the path becomes busy until the afternoon. If photography without crowds is a priority, arrive either very early (before 10:00 on a bicycle from the harbour) or after 16:00 when many day-trippers have returned to the ferry.

Safety

La Coupée has an excellent safety record — the iron railings have prevented any recorded fall since installation. Normal caution applies:

• Do not climb the railings for a better view or a better photograph.
• Keep children within arm’s reach.
• In strong wind, hold the railing.
• The concrete surface can be slippery in wet conditions — wear footwear with grip.
• Do not attempt to descend from the sides of La Coupée. The cliffs are unstable in places and the drops are fatal.

In exceptional weather: La Coupée is very occasionally closed or strongly discouraged in severe gale conditions. Local residents and accommodation owners will advise on current conditions.

Combining La Coupée with other Sark walks

La Coupée is most naturally combined with other walks on the southern section of Sark rather than visited as an isolated out-and-back trip.

The southern circuit (half-day from the village): Village → south road → La Coupée → Little Sark → La Grande Grève (tidal, check times) → return via La Coupée. Approximately 4-5 hours including the beach descent.

The western cliff extension: After La Coupée, return north and take the western coastal path back towards the harbour rather than the main road. This extends the walk by 1-2 hours but provides the most dramatic cliff scenery on the island. Allow a full day for this circuit.

Combined with kayaking: A morning kayak tour of the sea caves departs from the harbour. The approach to La Coupée from the sea level — looking up at the ridge from below, from a kayak — gives a perspective completely different from the land crossing. Some visitors combine the kayak tour (morning) with the La Coupée walk (afternoon) as a full-day Sark experience.

La Coupée in the Channel Islands context

La Coupée has no direct equivalent anywhere in the British Channel Islands. The other islands — Jersey, Guernsey, Herm, and Alderney — all have cliff paths and coastal scenery, but none has a single landmark that combines history, physical drama, and visual impact in the same concentrated form. For a comparison of the walking across the Channel Islands, see our best Channel Island for hiking guide.

It is the single most-cited reason for visiting Sark among visitors who describe the island to others. It appears in almost every article, guide, and travel piece ever written about the British Channel Islands. And it genuinely delivers — the experience of standing on that narrow concrete ridge above the sea, looking along the edge of the drop, is something that photographs suggest but cannot replicate.

Practical information

• Access: always open, no ticket required, no booking needed.
• Getting there: 2km south of the village by bicycle or foot. No other route.
• Bicycles: can be hired at the harbour or village for approximately £12-£15 per day.
• Time needed: allow a minimum of 30 minutes for La Coupée itself. Allow 1.5-2 hours to include a walk into Little Sark. Allow 3-4 hours for the full Little Sark circuit with La Grande Grève descent.
• Seasonality: La Coupée is accessible year-round, weather permitting. Access to the beach at La Grande Grève depends on the tide.

Frequently asked questions — La Coupée Sark

Is La Coupée safe for children?

Yes, with normal supervision. The railings are solid and the path is concrete. Younger children should hold an adult’s hand throughout the crossing. The crossing is not appropriate for children who are very frightened of heights.

Can you cycle across La Coupée?

Technically yes — the walkway is wide enough for a bicycle — but it is slow and awkward in practice. Most cyclists park their bicycle at the Big Sark end and cross on foot. The lane on the Little Sark side can also be cycled once you are across.

How long is La Coupée?

Approximately 90 metres — the length of a short street. The crossing takes 4-5 minutes at a normal walking pace.

Who built La Coupée?

The current concrete walkway was constructed in 1945 by German prisoners of war after the liberation of the Channel Islands, under Red Cross supervision. Prior to 1945, the crossing existed as an unprotected dirt path.

Is there anything to do on Little Sark?

La Grande Grève beach (tidal — check times), the ruins of the nineteenth-century silver mine, and some excellent cliff paths along the southern and eastern coasts. Little Sark is quieter and more isolated than Big Sark. It rewards a slow exploration rather than a rapid transit.
