The siren call of Île de Batz, one of the most enchanting Breton islands, is a powerful one—beckoning travelers in search of a Brittany island escape where life slows to the rhythm of the tides. Just a swift, fifteen-minute ferry ride from the historic port of Roscoff, this hidden gem of Brittany feels at once easily within reach and profoundly ‘elsewhere.’
Modest and low-lying—its name ‘Batz’ drawn from the Breton word for ‘low’—the island is a world apart from the bustle of the mainland. A verdant tapestry blessed by the Gulf Stream, it is a floating garden where palm trees sway above fields of the famed pomme de terre primeur (early potato), and coastal paths unfold with panoramic drama across land and sea.
For the discerning traveler in search of an authentic, tranquil, and richly rewarding French island holiday, Île de Batz is the ultimate discovery among the islands near Roscoff. It is less a destination to conquer than one to savor—step by slow step, breath by deep, sea-salted breath.

A Microclimate Miracle: The Island’s Exotic Heart
The true, unique selling proposition of Île de Batz is its astonishing flora, a botanical miracle sustained by a mild, oceanic microclimate. The island’s greatest treasure, and a mandatory first stop for any visitor, is the Georges Delaselle Garden.
Established in 1897 by the Parisian insurance broker Georges Delaselle, this 2.5-hectare garden is an oasis of global botany. Delaselle, captivated by the island’s unique conditions, amassed around 1,700 exotic and rare plant species from the world’s temperate zones.
Strolling through its winding paths is a journey from the Mediterranean scrubland to the cacti of the Americas, then onto the vibrant palms and towering bamboos of Asia. You’ll find yourself questioning if you’ve truly left Finistère, as aloes bloom alongside agapanthus, all thriving thanks to the maritime influence and the Gulf Stream’s warm embrace.
The garden is not merely an attraction; it is a testament to the island’s fertility and a dramatic counterpoint to the wilder coastal moorland. It offers a peaceful, structured beauty that balances the rugged, untamed allure of the island’s periphery.
The Grand Tour: Walking the Coastal Path
At just 3.5 km (2.2 mi) long and 1.5 km (0.9 mi) wide, Île de Batz is perfectly sized for exploration on foot or by bicycle. The 12 km (7.5 mi) circumnavigation—a ‘grand tour’ that takes approximately three hours at a relaxed pace—is the island’s essential pilgrimage.
This coastal path, part of the legendary GR34, offers an ever-changing spectacle of white-sand coves, dramatic granite rock formations, and views across the Morlaix Bay. Start your journey at the main village, Pors Kernoc, near the landing stage.
The village itself is a charming cluster of stone houses with blue shutters, a tiny church, and what is, reputedly, the smallest town hall in France. From here, you can choose your direction, but the path to the west offers some of the most emblematic sights.
The Île de Batz Lighthouse
Dominating the western horizon, this 44-meter (144-foot) tall granite sentinel is a landmark not to be missed. A climb up the 198 steps is an effort richly rewarded by a stunning 360° panorama.
From the summit, the patchwork fields of the island stretch out below, flanked by the deep blue of the English Channel and the scattered islets of Morlaix Bay. The former lighthouse keeper’s quarters now house a small museum detailing the maritime history of the island.
Pointe du Serpent
Heading north, the landscape transforms into a more rugged, ancient environment. This is the fabled ‘Serpent’s Hole,’ where legend says Saint Pol Aurélien, the Welsh monk who founded the island’s first monastery in the 6th century, cast the dragon that terrorized the inhabitants. The colossal granite boulders here speak to the island’s geological age and provide a spectacular photo opportunity.
Ruins of St Anne’s Chapel
On the eastern side, you will find the humble, weathered ruins of the 16th century chapel, built on the site of St Pol’s original monastery. These relics, often partially swallowed by the dunes and sand, are a beautiful symbol of the island’s long and turbulent history, surviving waves of Viking and English pillaging.
Where Land Meets Sea: The Island’s Daily Bread
Île de Batz maintains a powerful sense of community, with its roughly 500 inhabitants sustained by three main pillars: fishing, tourism, and above all, market gardening. As you walk the island, you will notice high stone walls surrounding the fields—a traditional defense against the salt-laden wind. Inside these enclosures, the famous early potatoes, carrots, cauliflower, and onions flourish, fertilized by goémon (seaweed) collected from the shore.
This agricultural identity is key to the island’s charm. It is a genuine, working community, not just a tourist stage set. This authenticity extends to the coastline, where you can find nearly 20 beaches and coves. Grève Blanche offers wild, dune-backed expanses perfect for contemplation, while Porz Reter seduces with its clear waters and idyllic setting. The mild climate makes swimming and water sports a pleasant possibility from late spring onwards.
Planning Your Island Getaway: Logistics and Living
When to Visit

Accommodation and Dining
While the island is small, it offers a range of options for those wishing to spend the night:
Hotels and Gîtes: Choose from places like the Jardin Colonial – Rêves De Mer or private gîtes (holiday homes), many of which highlight the island’s botanical charm or coastal views.
Youth Hostel: The Ostal Île de Batz provides a more budget-friendly stay, complete with an on-site restaurant.
Camping: Small campsites and cabin rentals let visitors immerse themselves fully in the island’s natural calm.
Dining on Île de Batz is a celebration of fresh, local produce. In the village, you’ll find crêperies, bars, and restaurants serving seafood freshly caught by island fishermen, complemented by the island’s renowned vegetables. Traditional Breton galettes (savory buckwheat pancakes), abundant seafood platters, and a glass of crisp local cider make the perfect accompaniment to the sea views.
A Retreat for the Soul
Île de Batz offers more than just sightseeing; it offers a profound sense of peace. There are no cars (other than a few service vehicles), the only sounds are the cry of the gulls and the gentle sigh of the waves. It is a place to digital detox, to reconnect with the simple joys of nature, and to appreciate the resilience of an authentic island culture.
Whether you are scaling the lighthouse for the view, wandering through a tropical garden in the middle of Brittany, or simply digging your toes into the soft white sand of a hidden cove, Île de Batz promises an unforgettable escape.
Pack your walking shoes, your curiosity, and prepare to be charmed by the untamed beauty and warm heart of this Breton gem. This is not just a vacation; it is a vital reminder of the extraordinary worlds that exist just a short boat ride away.
