Île de Batz · Finistère

On the Île de Batz, a former dune turned since 1897 into an exotic oasis: more than 1,500 species, a palm grove, a cactus garden, an Oceanian garden, a new New Zealand garden and the Villa Nast, devoted to the story of Georges Delaselle.

1 hour to 1 hour 30, about 2 hours if you take your time in the Villa Nast and stop along the way
Type of place
Exotic botanical garden, museum and Jardin Remarquable

Exotic and contemplative, between subtropical plants, sand, dry stone walls and sea views
Getting there
1 Penn ar C’hléguer, in the east of the Île de Batz. From Roscoff, take the boat for a crossing of about 15 minutes; the boarding point may vary with the tides. From the island’s landing stage, allow about 15 to 20 minutes on foot, about 1.2 km, to the garden, near the chapel of Sainte-Anne. An island taxi service can also take you there.

About

At the south-eastern tip of the Île de Batz, the Georges Delaselle Garden and Museum is one of the most unusual exotic gardens in Brittany. It all began in 1897, when Georges Delaselle, a Paris insurer with a passion for botany, discovered the island. Won over by its particularly mild ocean climate, he bought several plots of heath and dunes at Penn ar C’hléguer and set about acclimatising plants from Africa, Asia, America and Oceania. The project meant completely transforming the land. Georges Delaselle had windbreaks built, terraces laid out and a vast hollow dug into the heart of the dune, up to nearly five metres deep. Sheltered from the sea spray, this hollow became a microclimate where palm trees and subtropical plants thrive. The work also uncovered a Bronze Age necropolis, still part of the garden trail. Suffering from tuberculosis, Georges Delaselle settled on the island for good in 1918 and devoted the following years to his garden. After nearly forty years of work, he sold it in 1937 to the industrialist Robert Nast. The garden was occupied and damaged during the Second World War; Georges Delaselle died in 1944. In 1957, the estate was bought by the works council of Nord-Aviation. An exceptional cold snap in January 1963 destroyed much of the collections, and the garden gradually fell into oblivion. Its revival began in 1987 thanks to a handful of volunteers. The paths were cleared, the walls rebuilt and the collections replanted. The first visitors returned in 1988, and the association Les Amis du Jardin Georges Delaselle was founded in 1989. In 1997, for the garden’s centenary, the Conservatoire du littoral became its owner. The restoration was rewarded in 2006 with the Jardin Remarquable label. Since 2019, the site has been run by Haut-Léon Communauté with the Conservatoire du littoral and the association. Today, about 2.5 hectares are open to visitors. The trail brings together more than 1,500 species and passes through very different settings: the Palm Grove, the Cactus Garden, the Oceanian Garden, the Flowering Heath, the Coastal Forest and the Calvary. Georges Delaselle’s grave, where his ashes were moved in 2008, lies near the Calvary. In spring 2026, a new area inspired by the New Zealand bush opened, with about 150 New Zealand species. The visit now has a real museum dimension. Fully restored, the Villa Nast was inaugurated in 2023. It houses the ticket office and shop, as well as an indoor trail on the life of Georges Delaselle, the history of the garden and plant acclimatisation. One room also hosts temporary art exhibitions. A few months after the Villa Nast opened, Storm Ciarán on 1 and 2 November 2023 badly hit the line of trees that sheltered the garden from the wind. A major restoration campaign followed, and in 2024 the site was chosen as the Finistère winner of the Mission Patrimoine heritage programme. The creation of the New Zealand Garden in 2026 marks a new stage in this rebuilding, while carrying on the acclimatisation dream Georges Delaselle imagined more than a century ago.

  • Check the boat times before you leave: the Roscoff to Île de Batz crossing takes about 15 minutes, and the boarding point may vary with the tide.
  • Add about 15 to 20 minutes’ walk each way between the landing stage and the garden.
  • Start with the Villa Nast: knowing Georges Delaselle’s story and how he created his microclimate makes the Palm Grove and the other areas much more interesting.
  • Do not miss the New Zealand Garden: opened in 2026, it brings together about 150 species in an area replanted after Storm Ciarán.
  • Look out for the big trees and the newly replanted areas: the garden still bears the marks of Storm Ciarán in 2023 and its rebuilding.
  • The Villa Nast regularly hosts temporary exhibitions: check the programme before your visit.
  • Comfortable shoes are recommended: part of the visit is on outdoor paths, with sand, slopes and natural ground.
  • The site welcomes people with reduced mobility, but the island access and some outdoor paths may need more planning. Contact the garden if mobility is very limited.
  • The wind and weather can be very different between Roscoff and the tip of the garden: bring a jacket even when it is sunny on the mainland.
