Alma Harbour sits at the mouth of the Upper Salmon River where it empties into Salisbury Bay, in the small fishing village of Alma, Albert County, New Brunswick.

The harbour serves as the working base for the local lobster and scallop fishing fleet, and its operations are tightly governed by the extreme tidal range of the Bay of Fundy — vessels can only launch and return during a narrow high-tide window, missing which means waiting hours out in the bay.

The harbour is also a gateway for recreational water access, with the surrounding area offering ocean kayaking tours on the Bay of Fundy and river kayaking on the Upper Salmon River.

Fundy National Park's headquarters lies just across the river, making Alma Harbour a natural starting point for visitors exploring the region's tidal environment.
