Once the domain of smugglers, Les Ecrehous is wild, windswept, and hauntingly beautiful. Home to Britain’s largest breeding population of bottlenose dolphins, Les Ecrehous Reef is Jersey’s best-kept secret and it should be on your bucket list! 

Taking a RIB trip to Les Ecrehous islands is the highlights of my visits to Jersey. Visiting this tiny archipelago of islets just off the Jersey coast (and very close to France) is a magical experience.

In this post, I’ll share how to get to Les Ecrehous, what to do and see when you are there, and tell the story of “The King of the Ecrehous”. You’ll also find hints and tips to make your trip even more enjoyable 🙂

A RIB Trip To Les Ecrehous Islands

Les Ecrehous Reef is a small paradise of golden sand, crystal clear water, and rock, where fish and birds live in peace with the rhythm of some of the biggest tides in the world, largely undisturbed by man.

Where is Les Ecrehous Reef?

Les Ecrehous is situated just six nautical miles off the northeast coast of Jersey (in the British Channel Islands) and less than 10 miles from France’s Normandy coast.  

In 2005 these islets became a RAMSAR site, protecting the habitat of bottlenose and common dolphins, Atlantic grey seals, and basking sharks.

The three largest islets are called Maîtr’Île (Master Island), La Marmotchiéthe and Lé Bliantch’Île (White Island). The first two have a few stone huts and houses used as weekend or holiday hideaways – the others are uninhabited.

Maître Ile

The biggest islet, with two habitable huts. Visit to see the ruined fisherman’s cottages, plus the foundations of a 13th Century priory, with a small menhir (an ancient standing stone) inside it.

La Marmotchiéthe

This is where most RIB trips land. The islet has a tiny cluster of huts around a tiny courtyard dating back to 1800.

How to Get to Les Ecrehous from Jersey

The Les Ecrehous reef is only accessible by boat. While you can charter a boat for the day (or longer), be aware that Jersey has an enormous tidal range. 

Twice daily, 40 feet of water gushes in and out again, covering and uncovering all but the three largest islets of the Les Ecrehous Reef. Over the years, hundreds have drowned at the mercy of the vicious rocks around Jersey, and there have been many shipwrecks!!

So, unless you’re a competent sailor, you’ll need a local skipper to navigate the treacherous tides, currents, and sandbanks!

On my most recent trip, I saw a French yacht left high and dry on the beach. The skipper had moored up at high tide, unaware that the sea would go out as far as it did!

Yact over on its side as the goes out at Les Ecrehous

The best way to visit Les Ecrehous is on a RIB trip, and there are several good operators.

RIB Trip

We picked the 3-hour Dolphin, Seal, and Reef Exploration RIB trip to Les Ecrehous from Jersey Seafaris. They have a fun, knowledgeable crew who respect the wildlife and the reef’s environment.


If you’re an experienced kayaker, you can paddle (weather permitting!) to Les Ecrehous in about 2 ½ hours with Jersey Kayak Adventures.

What to Expect on Your RIB Trip to Les Ecrehous

Kitted out for Dolphin, Seal and Reef Exploration RIB Trip to Les Ecrehous

Before boarding the RIB, trips begin with a safety briefing from the crew. You’ll also get kitted out with a warm, waterproof jacket and life jacket. Even on a hot day, it’s pretty chilly offshore!

Top Tip: Wear water shoes or sandals with a strap. Flip-flops are not fun on the slippery, pebbly beaches of Les Ecrehous!

Once the passengers have boarded, the skipper fires up the RIB’s engines and casts off from the slipway. After puttering past St Catherine’s breakwater, the power is cranked up to around 30knts (38mph), for an exhilarating 15-minute blast across the waves northeast to Les Ecrehous.

 If you want to take photographs on the RIB trip, forget your “best” camera! Use a GoPro waterproof camera, as it’s a very “bouncy” ride with a lot of sea spray.

You may see a pod of dolphins swimming and jumping from the sea alongside the RIB on the way. Shout out to the crew if you do, as the skipper will slow down to let you take photographs!

As the islands appear, you’ll approach the Les Ecrehous sandbank, which is only revealed twice a day, at low tide, for about 20 minutes. 

“We jumped off the RIB and walked along the sandbank, freshly revealed by the tide as we arrived. It was surreal to walk on the seabed, in the middle of the ocean! Minutes later, the sea reclaimed the sandbank, and it disappeared beneath the waves.”

Hour Dolphin, Seal and Reef Exploration RIB Trip to Les Ecrehous

Before stopping at the main island, the skipper will pilot the RIB around the reef, giving you fantastic photo opportunities. You’ll probably also see grey seals basking in the sun on the rocks. 

Drop-off points vary depending on the height of the tide – the sea goes out a long way, and the reef triples in size at low tide.

The skipper will tell you where and when to meet for your return trip; then, you can explore the island independently.

Things To Do On Les Ecrehous

While the largest islet (Maîtr’ Île) is only 300 metres long by 150 metres wide, there is plenty to see and do on short boat trips to Les Ecrehous! 

See Bottlenose Dolphins and Grey Seals

You may have been lucky and seen some dolphins and seals as you approach the Ecrehous, from the RIB; however, you’ll have more chances to see seals from the rocky shoreline.

On your RIB ride back to Jersey, you’ll have another chance to see more dolphins – they often swim alongside the RIBs!

Explore unique sand, land and sea habitats  

Les Ecrehous is the perfect place to take kids who love exploring nature! There are umpteen rockpools to investigate, oysters growing wild on the rocks, and plenty of different types of shells to examine.

Enjoy golden sandy beaches

What could be better than a whole beach to yourself? It’s often the case on boat trips to Les Ecrehous, as visitor numbers are very limited.

Swim or paddle in shallow, crystal-clear waters

On a hot summer’s day, there’s nothing better than a swim in the clean, clear waters of the Ecrehous. As a bonus, if you’re travelling with kids, the water is shallow for a long way!

Potter around the weather-beaten stone huts and houses

There’s something quite magical about climbing high up on the rocks to where the few Ecrehous houses are perched, and pottering around the tiny courtyard.

You can imagine what it’s like on bleak, wintry days – or think about the time when these islands were a den of smugglers!

Try out paddle boarding or kayaking

While you’ll need to pre-book any watersports activities, the shallow, calm waters of the Ecrehous are the perfect place to enjoy time on the water 🌊🤿🛶

Where To Eat and Drink in Les Ecrehous

There are no food outlets on Les Ecrehous, nor anywhere to refill a water bottle. Most visitors take a picnic to enjoy. No picnic? Before you go, you can buy tasty sandwiches, snacks and drinks from the little café at the trip departure point in St Catherine’s.

While you can use a BBQ on the islands, strict conditions exist. You MUST avoid areas where birds are nesting and ensure that any hot spots are doused with seawater when you leave.

Realistically, with a maximum of 2 hours ashore, you’ll barely have time on your RIB trip for a BBQ to get hot, cook your food, and cool down enough to carry back home!

Whatever you do, you must carry every scrap of rubbish away! 

Houses on Les Ecrehous

A Brief History of Les Ecrehous Jersey

In the 17th century, smugglers used the islands to smuggle lead and gunpowder to nearby St Malo in France. The customs house built to quash this activity is still standing today.

Today the islands form part of the Island of Jersey, but sovereignty was hotly disputed for centuries, so France took the United Kingdom to the International Court of Justice (ICJ) in 1950 to decide to which country the Ecrehous belonged. On 17 November 1953, the ICJ awarded the islands to Jersey.

The King of The Ecrehous

In 1961, Alphonse le Gastelois started a 14-year self-exile on the islet of La Marmotchiéthe after false accusations that he was guilty of the horrific child sex crimes of the “Beast of Jersey”. A decade later, in 1971, Edward Paisnel was imprisoned for the crimes; however, Le Gastelois remained on the islands, proclaiming himself “The King of The Ecrehous”.

This is my home now! Jersey crucified me.

There are no food outlets on the islands, and nowhere to refill a water bottle, so most visitors take a picnic to enjoy. No picnic? Buy refreshments at the little café at St Catherine’s before you go.

Need To Know Information


👀 There are toilets at St Catherine’s, but none on the boat or Les Ecrehous. Check out the Les Ecrehous code of conduct for what to do if nature calls. 


This trip isn’t suitable if you have accessibility needs, a back problem, or for expectant women. Here’s why:

  • There’s quite a step down to the RIB from the slipway at St Catherine’s. The crew will help you, but you’ll be stepping down onto the side of an inflatable boat!
  • Depending on the tide, you may need to jump into shallow water, climb up a short ladder, or step aboard from an uneven stone jetty (where there are no railings).
  • The islands are remote and beautiful, but there’s nowhere to sit (except on your own backside/picnic blanket), and there are no paths. You’ll be walking across shingle, sand and rocks.
  • The RIB trip is fast and exciting – it’s also very bouncy!
