Gavrinis is a small island in the Gulf of Morbihan in Brittany, France, famous for its Neolithic passage grave containing richly carved stone slabs. The monument’s carved megalithic art is among the best-preserved examples from northwest Europe and dates to the late 4th or early 3rd millennium BCE.

The main attraction is the inner burial chamber with large stone slabs covered in abstract and symbolic engravings. Visits focus on a short guided entry into the covered passage and chamber to view the carved surfaces.

Built during the Neolithic by local megalithic communities, the tomb has been known to antiquarians and archaeologists since the 19th century and has been the subject of study for its art and construction techniques.

Gavrinis sits in the Gulf of Morbihan off the coast of Morbihan department in Brittany and is reached by a short boat crossing from nearby ports such as Larmor-Baden. The island and tomb are compact, and most visitors arrive by timed boat services.

  • Access and boat services: Landing and visitor boat services to the island run from ports such as Larmor-Baden and are seasonal, so check local timetables before planning a visit.

What to See #

  • Passage grave chamber: The passage grave chamber contains a decorated inner chamber made of closely fitted slabs; visitors view carved slabs with concentric motifs and stylised figures.

How to Get to Gavrinis #

Gavrinis is a small island in the Gulf of Morbihan, Brittany. From the regional centre of Vannes drive south to the coastal ports at Larmor‑Baden or Le Bono (around a 20-30 minute drive from Vannes) and park at the visitor landing; a short passenger boat transfer (typically about 5-10 minutes) connects the mainland landing to the island. On arrival the Neolithic cairn is a short walk from the island landing point.

Tips for Visiting Gavrinis #

  • Gavrinis is only accessible by boat from nearby mainland departure points (for example Larmor-Baden), so book crossings and the timed interior visit well in advance during summer when visitor numbers and boat services are limited.
  • Timed interior visits to the passage grave are strictly controlled - reserve the limited guided slots as they sell out quickly in high season rather than relying on walk-up availability.
  • Allow time before or after your island visit to see other Gulf of Morbihan megalithic sites or the visitor centre on the mainland, as many visitors rush the cairn itself and miss the explanatory displays that illuminate the carved slabs.
