The nature trail
Grimshaw and Lafortune cut about 4.8 km of paths. The main loop takes 30 to 60 minutes depending on your pace and stops. It is rocky and uphill in places, so wear proper shoes.

The granite island Brendon Grimshaw bought in 1962 and replanted by hand, now a national park you can walk round in an hour.
Moyenne Island is a small granite island in the Ste Anne Marine National Park, about 4.5 to 5 km off the northeast coast of Mahé in the Seychelles. Brendon Grimshaw, a Yorkshire newspaperman, bought it in 1962 and spent decades replanting it. It became a national park in 2009, and you can visit on a day boat trip from Mahé.

Moyenne is often called the world’s smallest national park, a description used by BBC Travel among others. It is a media label rather than an official ranking.
In 1962, on the last day of a holiday in the Seychelles, Brendon Grimshaw bought Moyenne for a reported £8,000. He was a newspaperman from Dewsbury in Yorkshire who edited papers in East Africa. The island had been largely abandoned since 1915, and when he arrived rats were almost the only wildlife.
He moved there in 1973. With René Antoine Lafortune, a fisherman’s son who was 19 when they started, he cleared scrub, cut paths and planted about 16,000 trees by hand. He brought in Aldabra giant tortoises and bred them. Birds came back too: about 2,000 live on the island now.
Grimshaw turned down a reported $50 million for Moyenne because he wanted it to be a national park for everyone. That happened in 2009. He died in 2012, aged 87, and is buried on the island beside his father. The foundation he set up runs it today.

One loop trail, 30 to 60 minutes on foot, passes beaches, lookouts and the graves, with tortoises wandering across it.

Grimshaw and Lafortune cut about 4.8 km of paths. The main loop takes 30 to 60 minutes depending on your pace and stops. It is rocky and uphill in places, so wear proper shoes.

Dozens of Aldabra giant tortoises roam free. BBC Travel counted nearly 50 in 2022, and hatchlings are raised in two nurseries.

The island’s only restaurant. Some tours, including the Creole Travel Services catamaran day, serve a barbecue lunch here. Others eat on Cerf Island instead.
Grimshaw is buried beside his father, Raymond. Nearby are two older graves marked “Unhappily Unknown”, found while clearing paths. Grimshaw believed pirates lay in them. Nobody knows who does.
Local lore says pirates buried treasure on Moyenne and that two men were killed so their spirits would guard it. Grimshaw and Lafortune never found any.
A small thatched chapel stands in the forest along the trail, and a small museum tells the story of Grimshaw and the island.
White sand and granite boulders, with a beach called Pirate’s Cove. Hawksbill turtles nest here, and the 2009 count of endemic palms included 13 coco de mer.
There is no public ferry, no hotel and no jetty. Most people come on an organised boat trip from Victoria or Eden Island Marina on Mahé, usually with snorkelling and lunch thrown in. A private charter is the alternative.

Moyenne is one of six islands in the park, which was declared in 1973 as the first marine protected area in the Seychelles. Its reefs and seagrass beds draw green turtles, and most boat trips stop to snorkel between the islands.

The island’s story, its tortoises and legends, and the practical side of a visit.

Olivier Levasseur, known as La Buse, was a French pirate hanged on Réunion in 1730.

Where to stay on Mahé, which tour to book and what to sort out before the boat.

For a Moyenne or marine park day, stay on Eden Island: Eden Bleu Hotel is a short walk from the boats.

Stay on Mahé if it's your first trip, your stay is short, or you want the Ste Anne Marine Park: the airport and the boats are there.

Eden Island is a man-made residential and marina island joined to Mahé by a bridge, between Victoria and the airport.

Mahé's marine park side is the north-east coast.

Seychelles can be expensive, but day-to-day fees are modest.
Mahé, Victoria and the wider islands, for the days you are not on Moyenne.

The best things to do in Mahé split between the water and the hills.

Most things to do in Seychelles sit on three islands.

The best time to visit Seychelles is April to May or October to November.

The best Seychelles snorkeling is inside the marine parks.

Seychelles island hopping runs on the Cat Cocos ferry: 1 hour 15 minutes from Mahé to Praslin, then 15 minutes on to La Digue.

Victoria is the capital of Seychelles and small enough to see on foot in half a day.

Beau Vallon is Mahé's busiest beach: almost 2 km of sand on the north-west coast, about 5 km by road from Victoria.

Anse Major is a small beach on Mahé's north-west coast with no road.

Morne Seychellois National Park covers 3,045 ha of Mahé's mountains, more than a fifth of the island, with over 15 km of trails.

Choose the Seychelles for variety: granite islands with mountains up to 905 m, rainforest hikes, giant tortoises and ferries between islands.
The Moyenne Island Foundation. Brendon Grimshaw set it up and left the island to it when he died in 2012. Under a 2013 agreement the foundation runs the island and the national parks authority gives technical support. The sea around it is part of the government-run Ste Anne Marine National Park.
Yes. Most visitors come on a day boat trip from Mahé that combines snorkelling and lunch with time ashore for the trail and the tortoises. There is no hotel and no jetty, so you wade ashore from a small boat. You pay the marine park fee and a separate landing fee, and many tours include both.
In the Seychelles. It is one of six islands in the Ste Anne Marine National Park, about 4.5 to 5 km off the northeast coast of Mahé and roughly 10 to 15 minutes by boat from Victoria. Its neighbours are Ste Anne, Round Island and Long Island.
Yes. Grimshaw signed an agreement with the government in 2008, and Moyenne was formally declared a national park in 2009. The Moyenne Island Foundation manages it, and it sits inside the protected Ste Anne Marine National Park.
About 9.9 hectares (0.099 square kilometres, or about 24 acres), roughly 400 m long and 300 m wide. Some sources give a smaller figure of about 9 hectares. A loop walk around the island takes 30 to 60 minutes.
Only staff. A warden lives on the island, in a house behind the restaurant, but there is no village and no hotel, so visitors come for the day. Brendon Grimshaw made Moyenne his home from 1973, and his father Raymond spent his last years there. Both are buried on the island.
Aldabra giant tortoises are the best known: dozens roam free (BBC Travel counted nearly 50 in 2022) and hatchlings are raised in two nurseries. About 2,000 birds live there, on an island that had almost none when Grimshaw arrived. Hawksbill turtles nest on the beaches, and snorkel stops in the marine park around it turn up parrotfish and angelfish.
By boat from Mahé. Organised day trips leave from Victoria, at Marine Charter and the Inter-Island Quay, and from Eden Island Marina, often with hotel pickup. A private boat charter is the other option. There is no public ferry.
