The site's seaside views make it a venue often favoured by photographers.

Observing the intertidal zone

The site offers a good viewpoint to observe the changes in the shoreline and harbour by the ebb and flow of the Bay of Fundy's tides which, at this location, rise and fall an average of 7.24 m (24 feet) twice every day. This dramatically changes what you can see of the coastal environment.

St. Andrews Blockhouse is adjacent to Passamaquoddy Bay, which flows into the Bay of Fundy. Visitors who venture away from shore should be watchful of the tide, as it is possible to become stranded by the rising tide.
