BOAT-COMPARATOR Guide

Houat and Hoedic by boat: the wild islands of the Mor Braz

White-sand beaches, the Grande Île anchorages, a Natura 2000 reserve: the guide to reaching Houat and Hoedic by boat from Quiberon or La Trinité-sur-Mer.

Off the Quiberon peninsula, two small Breton islands keep an end-of-the-world feel: Houat and Hoedic, the islands of the Mor Braz, the “great sea” that opens south of the Gulf of Morbihan. Car-free, with white-sand beaches worthy of the tropics, they are best discovered from the water — even though no rental base sits on them: you come from the nearby mainland.

Where to start

These islands have no rental fleet: you reach them from the neighbouring bases. Quiberon (Port Haliguen) is the most direct starting point, just a few miles out; La Trinité-sur-Mer, a sailing mecca, offers a wider fleet of sailboats. From either, you reach Houat in about an hour in workable seas. The same outing naturally extends a visit to Belle-Île, its big neighbour, or the Gulf of Morbihan.

Houat, the Treac’h er Goured beach

On Houat, the great beach of Treac’h er Goured, on the island’s east side, forms a vast crescent of sheltered white sand, one of the bay’s finest anchorages in a westerly wind. The small harbour of Saint-Gildas, on the north coast, welcomes visitors near the village. You anchor on sand, clear of the marked zones, and go ashore by dinghy to walk the coastal paths of this five-kilometre island.

Hoedic, smaller and more secret

Two miles further south, Hoedic is smaller still, lower, more confidential. Its tiny harbour of Argol and its dune-backed beaches make it a wonderfully gentle stop, less busy than Houat in high summer. Both islands offer few services: bring water and provisions from the mainland, as our what to pack guide reminds you.

Tides, currents and caution

The Mor Braz is Atlantic water: the tidal range is large and currents are noticeable in the passages between the islands and the mainland. Check the tide tables and time your crossing for a workable weather window, as our Atlantic tides guide explains. In a strong westerly or south-westerly, the crossing can quickly turn uncomfortable: these islands are earned in fair weather.

A protected natural heritage

Houat and Hoedic lie at the heart of a marine Natura 2000 site that protects remarkable habitats: maerl beds, eelgrass meadows, rocky bottoms with fixed fauna. Maerl, the calcareous alga that forms loose beds sheltering rich biodiversity, is especially sensitive to dredging and anchoring. A study by Grall and Hall-Spencer documented the threats facing Brittany’s maerl beds and the urgency of their conservation (see the study on Google Scholar) — one more reason to anchor on clear sand and never on these pale, gravelly beds that take centuries to rebuild.
