St. Martins sea caves from Saint John
Fundy coastal village, covered bridges, and tide-gated sea caves on a scenic drive from Port Saint John.
About St. Martins
St. Martins is a harbour village roughly 40 km east of Saint John — historic covered bridges, lobster shacks, and red sea cliffs mark the Fundy coast.
Tidal cave access
Sea caves and tidal falls are walkable at low tide only. Reputable scenic tours schedule stops against Fundy tide tables — independent visits without tidal research risk a wasted drive.
Fits a six-hour port call?
Often yes on a Bay of Fundy scenic tour — unlike Hopewell Rocks' longer drive. See tide timing guide.
Frequently asked questions
