The Island
One island. One causeway.
Île de tidal sits 900 m off the Brittany coast, reached by a causeway the sea covers twice a day.
The causeway
Walkable for a few hours around low tide, underwater the rest. Every crossing is staff-led — no “quick nip back” at half-tide.

Life on the island
Lodging
Bunk rooms of four in the old lifeboat station — warm, dry, well above the tide.
Meals
Three a day from the island kitchen. Dietary needs handled.
The lab
Desks for twelve, solid power, and a link for git pushes.
Supervision
1:4 staff ratio, on the island through every high tide. First-aid trained.
Safety
Crossings only in posted windows. Stranded hours are planned, not emergencies.
Getting there
Meet at the Saint-Broladre slipway at the low-tide window. Nearest station: Dol-de-Bretagne.
